Abstract:

Carbon capture and sequestration contains a group of technologies keeping thedifferentiation of CO2 from large industrial and energy related sources, transport toa storage location and long-term isolation from the atmosphere. Previous studiesof CO2 adsorption on low-cost iron metal oxide surfaces strongly encourage thepossible use of metal oxide as sorbents, but the tendency of magnetite particles toagglomerate causes a lowering of CO2 sorption capacity. This work investigates theadsorption behavior of CO2 on composite materials prepared coating a low-costcarbonized rice husk (cRH), commercial carbon black (CB) with magnetite fineparticles. The CO2 capture capacity of composites and based on rice husk materialswas evaluated the basis of the breakthrough times measured at atmosphericpressure and room temperature in a lab-scale fixed bed micro-reactor. To thisaim the reactor has been firstly operated for CO2 adsorption data with obtainedsamples.

Abstract:

This paper studies carbon capture and storage based on carbon emission. There are three main technical routes for CO2 emission reduction: pre-combustion capture, oxygen-rich combustion, and post-combustion capture; CO2 separation technology mainly includes: chemical absorption method, solid adsorption method, membrane separation method. CO2 capture needs to be transported to a special place for storage, which can be generally divided into geological storage, marine storage and chemical storage. Future carbon capture research will focus on cost savings and energy savings.

Abstract:

AbstractChanges are needed to improve the efficiency and lower the CO2 emissions of traditional coal-fired power generation, which is the main source of global CO2 emissions. The integrated gasification fuel cell (IGFC) process, which combines coal gasification and high-temperature fuel cells, was proposed in 2017 to improve the efficiency of coal-based power generation and reduce CO2 emissions. Supported by the National Key R&D Program of China, the IGFC for near-zero CO2 emissions program was enacted with the goal of achieving near-zero CO2 emissions based on (1) catalytic combustion of the flue gas from solid oxide fuel cell (SOFC) stacks and (2) CO2 conversion using solid oxide electrolysis cells (SOECs). In this work, we investigated a kW-level catalytic combustion burner and SOEC stack, evaluated the electrochemical performance of the SOEC stack in H2O electrolysis and H2O/CO2 co-electrolysis, and established a multi-scale and multi-physical coupling simulation model of SOFCs and SOECs. The process developed in this work paves the way for the demonstration and deployment of IGFC technology in the future.

Full text

Abstract:

Direct air capture (DAC) is an emerging negative CO2 emission technology that aims to introduce a feasible method for CO2 capture from the atmosphere. Unlike carbon capture from point sources, which deals with flue gas at high CO2 concentrations, carbon capture directly from the atmosphere has proved difficult due to the low CO2 concentration in ambient air. Current DAC technologies mainly consider sorbent-based systems; however, membrane technology can be considered a promising DAC approach since it provides several advantages, e.g., lower energy and operational costs, less environmental footprint, and more potential for small-scale ubiquitous installations. Several recent advancements in validating the feasibility of highly permeable gas separation membrane fabrication and system design show that membrane-based direct air capture (m-DAC) could be a complementary approach to sorbent-based DAC, e.g., as part of a hybrid system design that incorporates other DAC technologies (e.g., solvent or sorbent-based DAC). In this article, the ongoing research and DAC application attempts via membrane separation have been reviewed. The reported membrane materials that could potentially be used for m-DAC are summarized. In addition, the future direction of m-DAC development is discussed, which could provide perspective and encourage new researchers’ further work in the field of m-DAC.

Abstract:

The traditional detection method of CO2 concentration in seed respiration has defects such as low detection accuracy, low detection efficiency, and inability to monitor in real time. In order to solve these problems, we report a seed respiration CO2 detection system based on wavelength modulation spectroscopy (WMS) techniques in tunable diode laser absorption spectroscopy (TDLAS). This system uses a 2004 nm distributed feedback (DFB) laser as the light source, and a double-layer seed respiration device (about 1.5 L) is designed based on Herriott cell with an effective optical path of about 21 meters. Then, the second harmonic (2f) signal is extracted by the wavelength modulation method for CO2 concentration inversion. When the ambient temperature and pressure changes greatly, the corrected 2f signal is used for CO2 concentration inversion to improve the accuracy. A series of verification and comparison experiments have proved that the seed respiration CO2 detection system has the advantages of strong stability, high sampling frequency, and high detection accuracy. Finally, we used the developed system to measure the respiration intensity and respiration rate of 1 g corn seeds. The respiration intensity curves and respiration rate change details show that the seed respiration CO2 detection system is more suitable for a small amount of seeds than nondispersive infrared (NDIR) CO2 sensor and gas chromatography in real-time monitoring of the breathing process.

Abstract:

The technical and economic challenges are enormous in developing gas wells with a high CO2 content (> 50 mol %), such as the East Natuna gas field, which has 71 mol % (86 mass %). Carbon capture technology in gas wells with high CO2 content is studied to find a more economical one. In this study, the technology for capturing high concentrations of CO2 is varied from gas wells, Controlled Freeze Zone (CFZ), and cryogenic distillation which will be analyzed based on cost. Variations in the CO2 content of gas wells are 75 %, 80 %, 85 %, 90 %, and 95 % in mass fraction simulated using Aspen Plus V.11.0. Based on this research, CFZ technology and cryogenic distillation can obtain purity up to 99 % and recovery above 78 %. However, the total annual cost (annual capital and operating costs) of CFZ technology is lower than cryogenic distillation technology, so CFZ technology is suitable for capturing CO2 in gas wells with high CO2 content.

Abstract:

The urgent need for emission reduction due to climate change has spurred the development of carbon capture and storage (CCS) technologies, with carbon dioxide (CO2) hydrates emerging as a promising option due to their high storage capacity and cost-effectiveness. This paper provides an overview of the characteristics and formation mechanisms of CO2 hydrates, along with an exploration of mechanical and chemical methods to enhance CO2 hydrate formation. Thermodynamic additives are beneficial for reducing the formation pressure of CO2 hydrate, while mechanical methods and kinetic promoters play a positive role in improving kinetic parameters, especially when both are combined. To investigate the effectiveness of kinetic and thermodynamic promoters, this study explores the impact of various promoters on induction time, formation rate, phase equilibrium, and gas consumption. Additionally, the existing challenges of CO2 hydrate are discussed, and the future research directions are proposed. Based on this study, the hydrate method of CO2 capture technology is expected to assume a crucial role in marine carbon capture technology.

Abstract:

In this paper, an experimental investigation was conducted using Vehicle Emission Testing System to study on-road gaseous emissions (CO, THC, NOX, CO2) characteristics based on diesel oxidation catalyst (DOC) and catalyzed diesel particulate filter (CDPF) technology. The results show that after the implementation of DOC + CDPF device, CO, THC emissions are significantly reduced, while the NOX, CO2 emissions remain almost the same. Under steady conditions, the reduction percentages of CO, THC, NOX, CO2 emission factors are 56.0%, 66.0%, 18.3%, 17.5%, respectively. Under transient operation conditions, the reduction percentages of CO, THC, NOX, CO2 emission factors are found to be 43.2%, 65.9%, 13.7%, 10.9%, respectively. Addition to the THC emission factor, the emission factors of CO, NOX and CO2 in transient operation conditions are higher than steady conditions.

Abstract:

This paper presents research on CO2 capture by lime-based looping cycles. This is a new and promising technology that may help in mitigation of global warming and climate change caused primarily by the use of fossil fuels. The intensity of the anticipated changes urgently requires solutions such as the developing technologies for CO2 capture, especially those based on CaO looping cycles. This technology is at the pilot plant demonstration stage and there are still significant challenges that require solutions. The technology is based on a dual fluidized bed reactor which contains a carbonator - a unit for CO2 capture, and a calciner - a unit for CaO regeneration. The major technology components are well known from other technologies and easily applicable. However, even though CaO is a very good candidate as a solid CO2 carrier, its performance in a practical system still has significant limitations. Thus, research on CaO performance is critical and this paper discusses some of the more important problems and potential solutions that are being examined at CETC-O.

Abstract:

For achieving CO2 thermal reduction, a technology combining solid carbon activation and high-temperature CO2 reduction was proposed, named as activated-reduction technology. In this study, this technology is realized by using a circulating fluidized bed and downdraft reactor. Reduced agent parameters (O2/C and CO2 concentration) greatly affect the reduction effect of CO2. In addition, the effect of the activation process on different carbon-based materials can help to broaden the range of carbon-based materials used for CO2 reduction, which is also an important issue. The following three points have been studied through experiments: (1) the influence of the characteristics of the reduced agent (CO2 concentration and O2/C) on CO2 reduction; (2) the performance of different chars in CO2 reduction; and (3) the activation effect of solid carbon. The activation process can develop the pore structure of coal gasification char and transform it into activated char with higher reactivity. The CO concentration in the tail gas is a crucial factor limiting the effectiveness of CO2 reduction, with an experimentally determined upper limit of around 55% at 1200 °C. If CO concentration is far from the upper limit, temperature becomes the significant influencing factor. When the reduced agent O2/C is 0.18, the highest net CO2 reduction of 0.021 Nm3/kg is achieved at 60% CO2 concentration. When the reduced agent CO2 concentration is 50%, the highest net CO2 reduction of 0.065 Nm3/kg is achieved at 0.22 O2/C. Compared with CPGC, YHGC has higher reactivity and is more suitable for CO2 reduction. The activation process helps to reduce the differences between raw materials.

Abstract:

Capture and conversion of CO2 into value-added chemicals and fuels is one of the most sought-after hot points at the scientific frontier. Driven by renewable energy derived electricity, the heterogeneous electrocatalyic CO2 reduction has attracted intensive interests because of the easy manipulation and high-energy-density fuels supply. Metals with general abundance and robust ability for activating CO2 have been adopted as the core-atom for developing advanced CO2 reduction electrocatalysts. As the dramatic development of nano-technology, the nanostructured metal-based materials become promising candidates for various catalytic systems. In this Review article, a general introduction and principles applied in CO2 electroreduction are summarized and discussed. Then the proposed reaction pathways of the CO2 reduction were classified and elaborated depending on the products. The state of the art advances related to the nanostructured metallic electrocatalysts are addressed as well. At last, the remaining challenges and further prospects for the construction of new nanostructured electrocatalysts for CO2 reduction and improvement of existing ones have been presented.

Abstract:

At present, the energy consumption and carbon emissions of maritime transportation have raised concerns about environmental issues. A potential way to reduce carbon emissions from vessels is the use of chemical-based carbon capture and storage (CCS) technology. However, this technology faces challenges such as high energy consumption, large space occupation, and high processing costs. Therefore, the development of a technology with low energy consumption and compact CO2 storage is crucial to promote the advancement of CCS technology. This paper introduces a magnesium CO2 battery system that converts CO2 into new energy, in the form of hydrogen, while storing CO2. By preparing highly efficient catalytic electrodes and testing the electrolyte and CO2 flow rate on the battery performance, the optimal process parameters were determined to be Pd/CeO2-oct for the electrodes, a 0.5 mol/L NaOH solution for the electrolyte, and a CO2 flow rate of 1 L/h. The battery system demonstrated high cycling stability and conversion efficiency at a current density of 8 mA·cm−2, with a stable cycling time of 600 min (20 cycles), a cathode hydrogen production of 10.135 mL, and a Faraday efficiency of 97.03%.

Abstract:

This research examines the elaborate association between FI, CO2 emissions, and the moderating role of technological innovation across 83 countries. The study, which includes the years 2003 to 2022, uses data from the WDI to investigate the dynamics and consequences of these interrelated factors. The major goal is to determine the influence of FI on CO2 emissions, taking into consideration the moderating role of technical progress. Through principal component analysis, the study seeks to understand the underlying mechanisms driving these associations by employing various statistical approaches such as correlation analysis and Driscoll-Kraay standard errors. Initial data show a significant link between FI and CO2 emissions, but the degree of the association varies by nation. Furthermore, technological innovation has been shown to have a significant moderating effect, increasing the effect of FI on CO2 emissions. Based on these findings, the research suggests policies that make use of the associations between FI and technological innovation in order to promote sustainable development. Overall, this study advances our consideration of the complex relationship between FI, CO2 emissions, and technological innovation, providing significant insights for policymakers and stakeholders working for environmental sustainability and economic inclusiveness.

Abstract:

This year’s primary selections for the Drilling and Completion Fluids Technology Focus reflect now-well-established industrywide emphases on machine learning (ML), automation, and the achievement of successful drilling of CO2 storage wells. Enhanced methods of modeling and monitoring allow time and cost savings while surpassing safety goals and furthering efforts to optimize CO2 storage. Paper OTC 35433 discusses a study centered on accurate gel-strength estimation. The authors leverage ML techniques, particularly the use of artificial neural networks, to develop predictive models for forecasting the gel strength of synthetic oil-based mud systems at both 10-second and 10-minute intervals, surpassing the precision and speed of techniques based on traditional rotational viscometers. In a similar vein, paper SPE 216322 seeks to bypass traditional manual methods of monitoring drilling fluids, its authors describing a novel online system that measures 10 key parameters continuously. They write that the system has been field-trialed across 200 wells with results that highlight the system’s reliability, with continuous operation for over 125 days. Finally, paper SPE 217711 involves evaluating the effects of an influx of CO2 into drilling fluids, a key task in the drilling of CO2 storage wells. Concentrating on oil-based drilling fluid, the presented study describes the development and integration of models for properties of drilling-fluid/CO2 mixtures into an existing software suite. Recommended-reading papers include an investigation of the use of microwave power in recovering oil from contaminated drill cuttings, reduction of the carbon footprint of drilling fluids, and sedimentation behavior of particles in fibrous sweep fluids. As always, the long-sighted ambition of such research, and the skill applied in its pursuit, reflects the commitment to excellence embodied by the authors of technical papers presented at SPE conferences.

Abstract:

In recent years, CO2 flooding has become an important technical measure for oil and gas field enterprises to further improve oil and gas recovery and achieve the goal of “dual carbon”. It is also one of the concrete application forms of CCUS. Numerical simulation based on CO2-EOR plays an indispensable role in the study of the mechanism of CO2 flooding and buried percolation, allowing for technical indicators to be selected and EOR/EGR prediction to be improved for reservoir engineers. This paper discusses the numerical simulation techniques related to CO2 flooding and storage, including mathematical models and solving algorithms. A multiphase and multicomponent mathematical model is developed to describe the flow mechanism of hydrocarbon components–CO2–water underground and to simulate the phase diagram of the components. The two-phase P-T flash calculation with SSI (+DEM) and the Newton method is adopted to obtain the gas–liquid phase equilibrium parameters. The extreme value judgment of the TPD function is used to form the phase stability test and miscibility identification model. A tailor-made multistage preconditioner is built to solve the linear equation of the strong-coupled, multiphase, multicomponent reservoir simulation, which includes the variables of pressure, saturation, and composition. The multistage preconditioner improves the computational efficiency significantly. A numerical simulation of CO2 injection in a carbonate reservoir in the Middle East shows that it is effective for researching the recovery factor and storage quantity of CO2 flooding based on the above numerical simulation techniques.

Abstract:

Global warming and environmental pollution from greenhouse gas emissions are hitting an all-time high consistently year after year. In 2022, energy-related emissions accounted for 87% of the overall global emissions. The fossil fuel-based conventional power systems also need timely upgrades to improve their cycle efficiency and reduce their impact on the environment. Supercritical CO2 systems and cycles are gaining attention because of their higher efficiencies and their compatibility with varied energy sources. The present work is a detailed overview of the recent developments in supercritical CO2-based power generation technologies. The supercritical CO2-based Brayton and Rankine power cycles and their improvisations in industrial applications are also discussed in detail. The advances in heat exchanger technology for supercritical CO2 systems are another focus of the study. The energy, exergy, and economical (3E) analysis is carried out on various supercritical CO2 power cycles reported in the literature and the data are concisely and intuitively presented. The review concludes by listing the identified directions for future technology development and areas of immediate research interest. A roadmap is proposed for easing the commercialization of supercritical CO2 technologies to immediately address the growing challenges and concerns arising from energy-related emissions.

Abstract:

This paper aims at reducing greenhouse gas emissions, which contributes to carbon neutrality, and, at the same time, preventing mine heat disasters and extracting highly mineralized (HM) mine water, so as to realize the synergy between CO2 storage (CS) and geothermal extraction and utilization (GEU) in a high temperature (HT) goaf. With this purpose, an innovative CS-GEU technology for HT and HM water in deep mine is proposed, based on the mechanism of water-rock-CO2 effect (WRCE) and the principle of GEU in the mine. This technology uses GEU to offset the costs of CO2 storage and refrigeration in HT mine. A general scheme for a synergistic system of CS and GEU in the goaf is designed. The feasibility of CS-GEU technology in the deep goaf is demonstrated from the views of CS and GEU in the goaf and the principles of a synergistic system. It is clarified that the CO2 migration-storage evolution and the multi-field coupling principle in the goaf are the key scientific issues in realizing the synergic operation of CS and GEU. It proposes the key techniques involved in this process: CO2 capture and CO2 transportation, layout and support of drill holes and high-pressure (HP) pipelines, and HP sealing in the goaf. The research results provide new ideas for CS and GEU of HT and HM mine water in deep mine.

Abstract:

The utilization of natural gas as a primary feedstock in ammonia production has resulted in significant carbon dioxide (CO2) emissions, raising environmental concerns. Consequently, several technologies have been developed to capture and remove carbon dioxide. In this study, a comparison was conducted between two CO2 removal technologies (Amine and Benfield) in an Ammonia production plant. The evaluation was performed using rate-based modelling techniques in Aspen Plus software. A base case simulation was built and validated using figures obtained from various literature studies. Optimization and sensitivity analyses were conducted to determine optimal operating conditions. The optimized parameters were used to perform an economic analysis of both technologies based on the energy consumption, solvent regeneration efficiency, and CO2 removal efficiency. The results obtained from the comparison showed that the amine technology was more economical than the Benfield technology in terms of cost and plant efficiency. The economic analysis revealed that the amine technology had a lower Net Present value, and a shorter payback period compared to the Benfield technology. Overall, this study provides insight into the economic and operational considerations of CO2 removal technologies in ammonia production plants and recommends the use of amine technology as the preferred technology for CO2 removal in ammonia production plants.

Abstract:

Carbon Capture Utilization and Storage technologies are essential mitigation options to reach net-zero CO2 emissions. However, this challenge requires the development of sustainable and economic separation technologies. This work presents a novel CO2 capture technology strategy based on non-dispersive CO2 absorption and membrane vacuum regeneration (MVR) technology, and employs two imidazolium ionic liquids (ILs), [emim][Ac] and [emim][MS], with different behavior to absorb CO2. Continuous absorption–desorption experiments were carried out using polypropylene hollow fiber membrane contactors. The results show the highest desorption behavior in the case of [emim][Ac], with a MVR performance efficiency of 92% at 313 K and vacuum pressure of 0.04 bar. On the other hand, the IL [emim][MS] reached an efficiency of 83% under the same conditions. The MVR technology could increase the overall CO2 capture performance by up to 61% for [emim][Ac] and 21% for [emim][MS], which represents an increase of 26% and 9%, respectively. Moreover, adding 30%vol. demonstrates that the process was only favorable by using the physical IL. The results presented here indicate the interest in membrane vacuum regeneration technology based on chemical ILs, but further techno-economic evaluation is needed to ensure the competitiveness of this novel CO2 desorption approach for large-scale application.

Abstract:

Carboxylation reactions using carbon dioxide (CO2) as a reactant to produce new C-C bonds represent one of the most promising routes in carbon capture and utilization practices, which yield higher-atom and energy-efficient products. Kolbe–Schmitt-type reactions represent the carboxylation of aromatic compounds to their carboxylic acid derivatives. This study was the first and only to systematically investigate, thoroughly explain preparation procedures, and minutely describe the analytical methods of Kolbe–Schmitt and Marasse carboxylation of phenol. Most importantly, this study provides guidelines for the utilization of state-of-the-art technology in this century-old yet not sufficiently described reaction system. Kolbe–Schmitt carboxylation of phenol was found to be possible using sodium hydroxide (NaOH), potassium hydroxide (KOH), and sodium carbonate (Na2CO3), while the Marasse method was active only with potassium carbonate (K2CO3) as a reactant. The formation of metal phenoxide is the rate-determining step, which, however, could be more efficiently prepared under reflux. A new, simple, and repeatable HPLC method was described to identify and quantify all possible products of mono- and dicarboxylated phenols. It was found that all procedures result in the highest selectivity for salicylic acid (SA), followed by minor amounts of 4-hydroxybenzoic acid (4HBA) and 4-hydroxyisophthalic acid (4HiPh).

Mixed ionic-electronic conducting ceramic membrane-based oxygen separation technology attracts great attention as a promising alternative for oxygen production. The oxygen-transport membranes should not only exhibit a high oxygen flux but also show good stability under CO2-containing atmospheres. Therefore, designing and optimization, as well as practical application of membrane materials with good CO2 stability is a challenge. In this work, apart from discussion of literature data, authors’ own results are provided, which are focused on materia - related issues, including development of electrode materials exhibiting high ionic and electronic conductivities.

The aim of the research, presented in the paper, is to show and to assess the porosity structure in accordance to the dimensions of carbon dioxide particle. The characteristic surface morphology of the sample and the visualisation of the coal porous structure have been obtained using the atomic force microscope (AFM). The presented study of the coal microstructure is a part of the concepts of the project which aim is to develop the guidelines for design of the innovative technology of shale gas recovery with the use of liquid CO2. The technology will be based on Military University of Technology invention which considers gaseous hydrocarbons recovery from at least two levels of lateral wellbores with the use of supercritical CO2, what will result with wellbore productivity increase, because CO2 will cause desorption of CH4 from the porous structure of shale rock and the thermodynamic transformation of CO2 in the reservoir will help the rock fracturing. The heat energy added for the fracturing process will be taken from the surrounding rock mass.

Membrane reactors technology represents a promising tool for the CO2 capture and reuse by conversion to valuable products. After a preliminary presentation of the fundamentals of this technology, a critical overview of the last achievements and new perspectives in the CO2 conversion by membrane reactors is given, highlighting the still existing limitations for large scale applications. Among the low temperature (≤100 °C) membrane reactor for CO2 conversion, electrochemical membrane reactors and photocatalytic reactors, represent the two mainly pursued systems and they were discussed starting from selected case studies. Dry reforming of methane and CO2 hydrogenation to methanol were selected as interesting examples of high temperature (>100 °C) membrane based conversion of CO2 to energy bearing products.
