Resumo:

Multiple captures of small mammals (finding >1 animal in a single trap) are often used to infer pair-bonding activity in arvicoline and cricetine rodents. We analyzed data from a 2-year trapping study to determine whether fulvous harvest mice ( Reithrodontomys fulvescens J.A. Allen, 1894) and (or) northern pygmy mice (Baiomys taylori (Thomas, 1887)) travel in mixed-sex mated pairs. A significant majority of multiple capture events (MCEs) in R. fulvescens were mixed-sex, whereas sex composition of pairs in B. taylori did not differ from random. Multiple capture probability was significantly positively related to abundance and unrelated to sex ratio in both species. Multiple captures of B. taylori were more common in winter, suggesting that individuals may associate to huddle for warmth. Masses of singly captured and multiply captured individuals were not significantly different in either species, contraindicating trap bias. Only one co-captured mixed-sex pair was recaptured as a pair (in R. fulvescens) and several animals of both sexes in both species were co-captured with multiple individuals. We concluded that R. fulvescens co-travels with mates for variable lengths of time, but we found no evidence that multiple captures of B. taylori are related to reproductive behavior.

The need to cut CO 2 emission into the atmosphere is pushing scientists and technologists to discover and implement new strategies that may be effective for controlling the CO 2 atmospheric level (and its possible effects on climate change). One option is the capture of CO 2 from power plant flue gases or other industrial processes to avoid it entering the atmosphere. The captured CO 2 can be either disposed in natural fields (geological cavities, spent gas or oil wells, coal beads, aquifers; even oceans have been proposed) or used as a source of carbon in synthetic processes. In this paper, we present the options for CO 2 utilization and make an analysis of possible solutions for the conversion of large volumes of CO 2 by either combining it with H 2 , that must be generated from water, or by directly converting it into fuels by electrolysis in water using solar energy. A CO 2 –H 2 -based economy may address the issue of reducing the environmental burden of energy production, also saving fossil carbon for future generations. The integration of CO 2 capture and utilization with CO 2 capture and storage would result in a more economically and energetically viable practice of CO 2 capture.

Purpose Previous work has asserted that the co-innovation process in the music business is composed of four stages, i.e. co-discovery, co-creation, co-delivery and co-capture. This study aims to re-examine and validate this proposed conceptualisation by gathering and interviewing additional respondents, specifically academics and professional event organisers, who were not formerly involved. By gaining more insight from different stakeholders, this study expects to gain more reliable results regarding the proposed concept derived from the previous study. Design/methodology/approach This study uses the case study method by carrying out qualitative interview data collection from 11 respondents. Narrative analysis is used in examining the findings. Pattern matching is used as the basis of the analysis using the proposed conceptualisation from co-discovery to co-capture of co-innovation as the rival analysis to the empirical findings discovered in this study. This paper also discusses how the validity and reliability of the qualitative analysis carried out are ensured. Findings This study supports the notion that the co-innovation process in the music industry follows the four stages of co-discovery, co-creation, co-delivery and co-capture. The respondents, from different professional backgrounds, interviewed in this study indicated and validated that the proposed framework aligns with their actual practices, expectations and realities, along with their specific roles in the music industry’s ecosystems. Practical implications The results of this study can be used as a reference in developing guidelines or policies for co-innovation practices in the music business, which previous studies have not explored, e.g. focusing only on preconditions for positive collaboration, open license and music for co-creation or discussions that are merely conceptual. Originality/value This study validates the co-innovation process in the music business proposed by the previous works, which integrates the value chain thinking concept within the analysis.

Technologies that can capture CO2 and enable conversion into value-adding chemicals and fuels or stable minerals for sequestration are vital for transitioning towards net zero or even negative greenhouse gas emissions. Conventional approaches for electrochemically converting CO2 have utilized a decoupled approach of first capturing and concentrating CO2, and then using the concentrated CO2 as a feedstock for conventional electrochemical processes. Direct electrochemical reduction of amine-captured CO2 1,2 can potentially offer advantages by removing the need to thermally regenerate the amine capture solution, which can be energy intensive and typically uses thermal energy from nonrenewable sources. In this talk, we share our recent work on the electrochemical reduction of amine-captured CO2 to value-adding products like CO and stable minerals like carbonates. We discuss the influence of the capture environment on the resulting capture solution chemistry, and how to alter the capture solution speciation through electrolyte design. We further consider the detailed CO2 reduction mechanisms in these amine-containing solutions and provide design strategies for increasing the Faradaic efficiency of CO2 reduction vs. the competitive hydrogen evolution reaction (HER), as well as decreasing the overpotential of CO2 reduction.

Electron thermalization in X irradiated liquid CO is truncated by electron capture to form an anion, as it is in liquid N2. The thermalization distance distribution in these two liquids is a modified exponential, rather than the modified Gaussian obtained in liquid hydrocarbons where electron capture does not occur. The density normalized distance parameter bEPd in CO was constant, 2.8 × 10−6 kg/m2, at densities [Formula: see text], but increased somewhat at lower densities, reaching 3.3 × 10−6 kg/m2 at d/dc = 1.4. The thermalization distances in CO are about two thirds those in N2 at the same density. Electrons are captured more readily by CO than by N2.

Hydrocarbon fuel synthesis with renewable energy and captured CO2is a promising option for CCU and an important approach to sustainable energy. Like photosynthesis of plants, the technology of CO2direct captured from atmosphere with CO2utilization would close the carbon cycle thoroughly. Because of the dilute CO2in the atmosphere, the air capture process faces the challenge of high energy penalty. However, integrated with fuel synthesis process, the air capture process can take advantage of the waste heat produced by syngas production process and the transportation of CO2can also be avoided. In this study, a thermodynamic model of the fuel synthesis system is built through energy and exergy analysis. The thermodynamic contribution of three typical CO2capture technologies, moisture swing air capture, high-temperature swing air capture and traditional amine-based flue gas capture, is studied using the model built. Furthermore, by the sensitivity analysis of the critical parameters of the capture, electrolysis and heat exchange process, the influence of each process on the performance of fuel synthesis system is examined and the approach to improve the efficiency of the total system is proposed.

Carbon Capture and Storage (CCS) is one of the global leading methods that could potentially retard the speed of climate change. However, CCS on point sources can only slowdown the rate of increase of atmospheric CO2 concentration. In order to mitigate CO2 released by previous emissions, a more proactive alternative is proposed where CO2 is directly extracted and captured from air Direct Air Capture (DAC). This paper presents a technical overview from our current research of a novel DAC concept which features a phase of axial compression to adapt pre-capture atmospheric air to a level suitable for carbon capture. Also detailed in the paper is the feasibility study addressing several key issues: the energy consumption and overall capturing efficiency of the proposed DAC system.

This thesis is mainly concerned with the study of solvents of relevance for carbon capture and storage (CCS). The current industrial approach relies on amines to capture CO2, however this thesis describes a range of alternative non-amine based solvents, particularly phenols, saturated and unsaturated aliphatic acids, long chain fatty acids, aromatic acids, and β-dicarbonyl compounds (mainly ketones and esters). The CO2 capture capacities of these substrates have been compared with the industrial model substrate (monoethanolamine, MEA). From this study, phenols show 49-90% CO2 capture capacity whereas aromatic phenolic acids such as gallic acid show up to 100% theoretical CO2 capture capacity. Acetylacetone, a β-diketone shows 88% and the rest of the substrates from this and other groups show 50-60% CO2 capture capacity. However, some of the substrates, particularly simple mono and polycarboxylic acids showed negligible CO2 capture capacity, which can be understood on the basis of pKa. Particular attention has been paid to understanding the formation of bicarbonate salts, which would be expected under aqueous conditions. Clear evidence for their formation is provided by 13C NMR studies. The measured CO2 capture capacities of the new substrates have been correlated with pKa values. Those with pKa values between 9-13 have excellent to good CO2 capture capacity whereas others having pKa < 7, have insignificant CO2 capture capacity. The substrates with low pKa capture less volume of CO2 compared to those having high pKa, but release it more easily on heating. The second body of work is a study on the chemistry of MEA and its oxidised derivatives. MEA is currently the industry standard for CO2 capture. Given that power station flue gases contain large amounts of oxygen, and trace metals which may act as oxidation catalysts, understanding the chemistry of oxidised MEA derivatives is of increasing importance. This can have a significant effect on solvent activity and lifetime, which are important aspects of the economic profile of CCS. MEA was oxidised under a variety of conditions, and a complex mixture of products was formed. Many of these have been unambiguously identified by comparison with commercial or synthetic samples. The main oxidation products were then heated at 100°C for prolonged periods of time to mimic conditions in a commercial CCS system. Thermal degradation of MEA oxidation products was clearly observed, and in some cases, could be rationalised on the basis of established organic reactivity.

Thesis (S.M.)--Massachusetts Institute of Technology, Dept. of Chemical Engineering, 2009.
Includes bibliographical references (leaves 182-185).
The objective of this thesis is to evaluate a new carbon dioxide compression technology - shock compression - applied specifically to capture-enabled power plants. Global warming has increased public interest in carbon capture and sequestration technologies (CCS), but these technologies add significant capital and operating cost at present, which creates a significant barrier to adoption. Carbon dioxide compression technology makes up a high proportion of the additional cost required, making it a focal point for engineering efforts to improve the economic feasibility of carbon capture. To this effect, shock compressors have the potential to reduce both operating and capital costs with supporting compression ratios of up to 10:1, requiring less stages and theoretically allowing for the possibility of heat integration with the rest of the plant, allowing waste heat to be recovered from hot interstage compressed carbon dioxide. This thesis first presents a technical context for carbon dioxide compression by providing an overview of capture technologies to build an understanding of the different options being investigated for efficient removal of carbon dioxide from power plant emissions. It then examines conventional compression technologies, and how they have each evolved over time. Sample engineering calculations are performed to model gas streams processed by these conventional compressors. An analysis of shock compression is carried out by first building a background in compressible flow theory, and then using this as a foundation for understanding shock wave theory, especially oblique shocks. The shock compressor design is carefully analyzed using patent information, and a simulation of the physics of the shock compressor is created using equations from the theory section described earlier.
(cont.) A heat integration analysis is carried out to compare how conventional compressor technologies compare against the new shock compressor in terms of cooling duty and power recovery when integrated with the carbon dioxide capture unit. Both precombustion IGCC using Selexol and post-combustion MEA configurations are considered and compared. Finally an economic analysis is conducted to determine whether shock compression technology should be attractive to investors and plant managers deciding to support it. Key factors such as market, macroeconomic and technical risk are analyzed for investors, whereas a comparison of capital and operating cost is carried out for plant managers. Relevant risks associated with new compression technologies are also analyzed. It is found that there is no significant operating cost benefit to the shock compressor over the conventional compressor, both costing $3,700/hr for an IGCC plant. Power recovery is simply too low to justify the high power requirements in operating a shock compressor with a 10:1 ratio. The technical claims of the shock compressor (such as projected discharge temperature and pressures) seem reasonable after basic modeling, which shows a higher temperature and pressure than claimed by Ramgen.

Resumo:

As concerns mount about the rise in atmospheric CO₂ concentrations, many different routes to reduce CO₂ emissions have been proposed. Of these, post-combustion CO₂ capture from coal-fired power stations is often the most controversial, as the CO₂ capture system will remove generating capacity from the grid whereas many of the other solutions involve increasing the generating capacity of the grid with low CO₂-emission plants. Despite this, coal-fired power stations represent a major point source for CO₂ emissions, and if a consensus is reached on the need to reduce CO₂ emissions, a low-cost method for capturing and storing the CO₂ released by these power plants needs to be developed. The overarching goal of this research is to design and develop a novel hollow fiber sorbent system for post-combustion CO₂ capture. To achieve this goal, three objectives were developed to guide this research: i) develop a conceptual framework for hollow fiber sorbents that focuses on the energetic requirements of the system, ii) demonstrate that hollow fiber sorbents can be created, and a defect-free lumen layer can be made, iii) perform proof-of-concept CO₂ sorption experiments to confirm the validity of this approach to CO₂ capture. Each of these objectives is addressed in the body of this dissertation. Work on the first objective showed that fiber sorbents can combine the energetic advantages of a physi-/chemi-sorption process utilizing a solid sorbent while mitigating the process deficiencies associated with using solid sorbents in a typical packed bed. All CO₂ capture technologies--including fiber sorbents--were shown to be highly parasitic to a host power plant in the absence of effective heat integration. Fiber sorbents have the unique advantage that heat integration is enabled most effectively by the hollow fiber morphology: the CO₂-sorbing fibers can behave as "adsorbing heat exchangers." A dry-jet, wet-quench based hollow fiber spinning process was utilized to spin fibers that were 75wt% solid sorbent (zeolite 13X) and 25wt% support polymer (cellulose acetate). The spinning process was consistent and repeatable, allowing for production of large quantities of fibers. The fibers were successfully post-treated with an emulsion-based polymer (polyvinylidene chloride) to create a defect-free lumen side coating that was an excellent barrier to both water and gas permeation. A film study was conducted to elucidate the dominant factors in the formation of a defect-free film, and these factors were used for the creation of defect-free lumen layers. The work discussed in this thesis shows that the second objective of this work was definitively achieved. For the third objective, sorption experiments conducted on the fiber sorbents indicated that the fiber sorbents CO₂ uptake is simply a weighted average of the support material CO₂ uptake and the solid sorbent uptake. Furthermore, kinetic experiments indicate that CO₂ access to the sorbents is not occluded noticeably by the polymer matrix. Using the fiber sorbents in a simulated rapid thermal swing adsorption cycle provided evidence for the fiber sorbents ability to capture the sorption enthalpy released by the CO₂-13X interaction. Finally, a slightly more-pure CO₂ product was able to be generated from the fiber sorbents via a thermal swing/inert purge process.

The application of solid adsorbents for gas separation in pre-combustion carbon capture from gasification processes has gained attention in recent times. This is due to the potential of the technology to reduce the overall energy penalty associated with the capture process. However, this requires the development of solid adsorbent materials with large selectivity, large adsorption capacity, fast adsorption kinetics for CO2 coupled with good mechanical strength and thermal stability. In this work, results on CO2 adsorption performance of three different types of adsorbents; a commercial activated carbon, phenolic resin activated carbons and zeolite templated carbons have been reported at atmospheric and high pressures conditions. The commercial activated carbon was obtained from Norit Carbons UK, the phenolic resin activated carbon was obtained from MAST Carbon Ltd., while the templated carbons were synthesized in the laboratory. A commercial activated carbon was used as bench mark for this study. Surface modification of these carbons was also undertaken and their CO2 uptake measurements at ambient and high pressure conditions were recorded. The commercial and templated carbons were modified by functionalising with amine group, while the phenolic resin carbon was modified by oxidation. The textural properties of the adsorbents was examined using the Micromeritics ASAP, while the CO2 adsorption capacities were conducted using the thermogravimetric analyser (TGA) and the High pressure volumetric analyser (HPVA). Textural properties of synthesized templated adsorbents were seen to depend on the textural characteristics of the parent material. The β-type zeolite produced the carbons with the best textural property. Increase in activation temperature and addition of furfuryl alcohol (FA) enhanced the surface area of most of the templated carbons. The textural property of all the adsorbents under study was seen to differently affect the CO2 uptake capacity at atmospheric (0.1 MPa) and high pressure conditions (up to 4 MPa). Micropore volume and surface area of the commercial activated carbons, phenolic resin activated carbons, and the templated carbons greatly influenced the adsorption trends recorded at ambient conditions. Total pore volumes positively influenced adsorption trend for templated carbons, but not the phenolic resin activated carbons at ambient and high pressure. This also positively influenced the adsorption trend for the commercial activated carbons, but at ambient conditions only. The surface area and the micropore volume have no effect on the adsorption trends for the templated carbons and the commercial activated carbons at high pressure conditions. However, these played a positive role in the adsorption capacities of the phenolic resin activated carbons at the same experimental conditions. Micropore volume and surface area of adsorbents play a major role on the adsorption trends recorded for the modified adsorbents at ambient conditions only. No trend was recorded for adsorption capacities at high pressure conditions. Only the oxidized phenolic resin activated carbon showed a positive adsorption trend with respect to total pore volume at high pressure condition. The amine modified commercial activated carbon showed no positive adsorption trend with respect to the total pore volume at both ambient and high pressure conditions, while the amine modified templated carbon showed no adsorption trend with respect to the textural properties at ambient and high pressure conditions. CO2 uptake measurements for the modified and unmodified templated carbon and phenolic resin carbon, were observed to be higher than those of the commercial activated carbon at ambient and high pressure conditions. Maximum CO2 uptake was recorded at 25 oC. At ambient pressure, the phenolic resin carbon (MC11) showed the highest CO2 uptake of approximately 3.3 mmol g-1, followed by the commercial activated carbon (2.4 mmol g-1), then, the templated carbon (2.4 mmol g-1). At high pressure, the templated carbons (β-AC7-2%) showed the highest CO2 uptake (21.3 mmol g-1), followed by phenolic resin carbon (MC4 - 12.2 mmol g-1), and the commercial activated carbon (6.6 mmol g-1). When samples were modified, the amine modified templated carbon and oxidized phenolic resin carbon showed the highest CO2 uptake of 2.9 mmol g-1 each at ambient pressure, followed by the commercial activated carbon (2.7 mmol g-1). At high pressure conditions, the oxidized phenolic resin carbon showed the highest (10.6 mmol g-1) uptake level, followed by the templated carbon (8.7 mmol g-1), and commercial activated carbon (6.5 mmol g-1).

Amine functionalized silicas are promising chemisorbent materials for post-combustion CO₂ capture due to the high density of active sites per unit mass of adsorbent that can be obtained by tuning the synthesis protocol, thus resulting in high equilibrium CO₂ adsorption capacities. However, when compared to physisorbents, they have a few disadvantages. Firstly, oxidative degradation of the amine groups reduces the lifetime of these adsorbent materials. Furthermore, rapid heat release following the reaction between amines and CO₂ results in large local temperature spikes which may adversely affect adsorption equilibria and kinetics. Thirdly, there is a lack of fundamental understanding of CO₂-amine adsorption thermodynamics, which is key to scaling up these materials to an industrial-scale adsorption process. In this dissertation the qualitative and quantitative understanding of these three critical aspects of aminosilica adsorbents have been furthered so these materials can be better evaluated and further tuned as adsorbents for post-combustion CO₂ capture applications.

Increased levels of carbon dioxide in the atmosphere are now widely attributed as a leading cause for global climate change. As such, research efforts into the capture and sequestration of CO2 from large point sources (flue gas capture) as well as the ambient atmosphere (air capture) are gaining increased popularity and importance. Supported amine materials have emerged as a promising class of materials for these applications. However, more fundamental research is needed before these materials can be used in a practically relevant process. The following areas are considered critical research needs for these materials: (i) process design, (ii) material stability, (iii) kinetics of adsorption and desorption, (iv) improved sorbent adsorption efficiency and (v) understanding the effects of water on sorbent adsorption behavior. The aim of the studies presented in this thesis is to further the scientific community’s understanding of supported amine adsorbents with respect to stability, adsorption efficiency and adsorption behavior with water.

Resumo:

China has been building at least 50GW of new coal‐fired power plants every year since 2004. Previous carbon capture and storage (CCS) research has mainly focussed on technology improvements or stakeholder opinion surveys, without picturing the overall concerns and barriers for deploying such technology in China. This thesis therefore explores the engineering and policy requirements to implement CCS and CO2 Capture Ready (CCR) in Chinese coal‐fired power plants, key enablers for future deployment. A preliminary study of the Chinese gasification industry shows there are early opportunities to capture carbon dioxide from gasification plants. However, as power from conventional pulverised coal (PC) accounts for the majority of electricity generated in China, the most promising emission reduction method for China could be through implementation of CCS technology in large PC plants. An investigation of the current PC plant layouts and operating parameters has been carried out during the course of the study. The results show that, in the absence of CCR designs, a large fraction of such new coal power plants built within the next decade could face ‘carbon lock-in’. A site specific system model using ASPEN Plus to demonstrate the possible changes that could be applied to an existing power plant and a retrofit plant is included in the study. A capture ready power plant site selection method has also been developed, to identify possible sites and to aid understanding of the criteria that should be considered when planning a capture ready plant. A case study of a capture ready power plant in Guangdong province, China shows the benefit of regional planning. Finally, the result of the first stakeholder perception survey on making new coal‐fired plants CCR, conducted in early 2010, are presented and analysed. Evidence for a supportive attitude towards CCR could indicate that this may be a route to early commercial demonstration of CCS in China.

Resumo:

Aiming to mitigate the environmental impact derived from fossil fuels, we propose an integrated carbon capture-biomass gasification process is proposed to produce low-carbon hydrogen as an alternative energy carrier. The process begins with the pre-treatment of empty fruit bunches (EFB), involving grinding, drying, torrefaction, and pelletization. The resulting EFB pellet is then fed into a dual gasifier, followed by a catalytic cracking of tar and water gas shift reaction to produce syngas, aiming to increase its H2 to CO ratio. Subsequently, we explore two alternatives (DEPG and MEA) for syngas upgrading by removing CO2. Finally, a PSA system is modeled to obtain H2 at 99.9% purity. The pre-treatment stage densifies the biomass from an initial composition (%C 46.47, %H 6.22, %O 42.25) to (%C 54.10, %H 6.09, %O 28.67). The dual gasifier operates at 800�C, using steam as a gasifying agent. The resulting syngas has a volume concentration (%CO 20.0, %CO2 28.2, %H2 42.2, %CH4 5.9). Next stages of the process focus on removing the CO2 and increased H2 through catalytic reactions from the syngas. Thus, the DEPG carbon capture process can decrease the CO2 concentration to 2.9%, increasing the hydrogen to 95.6% in volume. In contrast, the MEA process reduces the concentration of CO2 to 5.2% and increases the concentration of H2 to 93.1%. Moreover, we estimate a levelized costs of hydrogen (LCOH) and carbon capture cost for each method (DEPG and MEA) (LCOC) and CO2 avoided (LCCA). LCOH: 3.05 USD/kg H2, LCOC: 92 and 59 USD/t CO2 and 183 and 119 USD/t CO2, for DEPG and MEA respectively.
