Повний текст джерелаGlobal warming, largely resulting from anthropogenic emissions of carbon dioxide, continues to remain a matter of great concern. Carbon capture and storage (CCS) is a viable solution to ensure a prevised fall in CO2 emissions from large point sources involving fossil fuel combustion. In this context, aqueous alkanolamine systems offer a promising near-term solution for CO2 capture from power generation facilities. However, these face several operational hitches such as equilibrium limitations, high regeneration energy requirement, solvent loss, and soaring corrosion occurrence. The main culprit in this respect is water and, accordingly, one feasible practice may be the replacement of aqueous phase with some stable solvent. Room-temperature ionic liquids (RTILs), with high thermal stability and practically no volatility, are emerging as promising aspirants. Moreover, owing to the tunable nature of ionic liquids, RTIL phase can be adapted in accordance with the process requirements. Replacing aqueous phase with RTIL in case of alkanolamine based processes provided a potential opportunity for efficient CO2 capture. The most striking aspect of these schemes was the crystallization of CO2-captured product (carbamate) inside the RTIL phase that not only helped evade equilibrium constraints but also rendered a worthy opportunity of product separation. Since there is little information available in the literature about the viability of amine-RTIL systems, the proposed research was aimed at better understanding CO2 separation proficiency of these fluids through a more systematic approach. Imidazolium RTILs ([Cnmim][Tf2N], [Cnmim][BF4], [Cnmim][Otf]) were chosen for this purpose. Two alkanolamines, 2-amino-2-methyl-1-propanol (AMP) and diethanolamine (DEA) were examined in detail to explore CO2 capture and regeneration capabilities of amine-RTIL systems. The results revealed the superiority of DEA-RTIL combination as this scheme could help significantly narrow the gap between absorption and regeneration temperatures thus promising a sparkling prospect of attenuating energy needs. Furthermore, ionic liquids were scrutinized in reference to their hydrophobic/hydrophilic nature to study the corrosion behaviour of carbon steel in amine-RTIL media. Though hydrophilic ionic liquids helped decrease corrosion occurrence up to 72%, hydrophobic RTIL appeared to be the most effective in this regard, virtually negating the corrosion phenomenon under CO2 rich environment. In case of immiscible blends like DEA-[hmim][Tf2N], continual agitation appeared to be a necessity to ensure a prolonged dispersion of amine in the RTIL phase and, thereby, to attain an optimal capture rate.

Повний текст джерелаSorption-enhanced steam reforming (SESR) is a forefront technology to produce H2 clean fuel, which integrates both CO2 capture and H2 production in a single process. The main objective of this work is to develop novel high-temperature CO2 sorbents and to investigate their application in SESR operation. Special attention was given to lithium zirconate (Li2ZrO3), sodium zirconate (Na2ZrO3) and calcium oxide (CaO)-based materials, as most famous high temperature CO2 sorbents, by applying two novel synthesis techniques. The application of Li2ZrO3 in CO2 capture sorption showed an increase in activity of the material prepared by surfactant template/sonication method compared to Li2ZrO3 prepared by simple surfactant template method (without sonication) or conventional wet-mixing route. Nevertheless, porous Li2ZrO3 still suffered from slow kinetics of CO2 sorption at low CO2 partial pressure (below 0.75 bar), which can limit its application for SESMR operation. Taking into consideration the improvement of Li2ZrO3 sorption properties, the same surfactant template/sonication technique was then applied to develop porous Na2ZrO3. The behavior of the new developed Na2ZrO3 was unexpected. The samples prepared by surfactant template/sonication technique were found to be less active than the conventional Na2ZrO3 during cyclic operation, due to the low resistivity of the pore structure at the very high temperature treatment required for calcination. The same surfactant template/sonication was also applied to develop Zr-stabilized CaO sorbents. An optimum Zr/Ca ratio of 0.303 was found to maximize the stability and CO2 capture activity of the proposed Zr-stabilized CaO sorbent. The results generally showed a better CO2 capture ability of Zr-stabilized CaO sorbent in comparison with pure CaO in severe cyclic operating conditions. With the purpose of reducing the cost of sorbent production, a cheaper source of CaO (natural limestone) was also considered and a novel synthesis technique (limestone acidification by citric acid followed by two-step calcination (in Ar and air atmospheres)) was applied in order to prepare highly porous CaO structure with unique CO2 capture ability. The results revealed a much better stability and CO2 sorption activity of the developed sorbent compared to natural limestone. The same technique was employed to develop a number of metal oxide (Al, Zr, Mg and Y)-stabilized CaO sorbents in order to enhance sorbent stability in severe operating conditions, i.e., high temperature regeneration in the presence of CO2. Al and Zr-stabilized CaO showed the best activity during both mild and severe operating conditions. The performance of the developed CO2 sorbents providing the best performance in CO2 capture (Zr-stabilized and Al-stabilized CaO) were then investigated experimentally in the sorption enhanced steam methane reforming (SESMR) using a fixed-bed reactor. To minimize the diffusional limitations, a hybrid catalyst-sorbent was developed for both sorbents. The application of Zr-stabilized CaO-nickel hybrid catalyst with 20.5 wt% NiO loading, prepared by surfactant-template/sonication method, resulted in 92% H2 production efficiency for the initial SESMR cycle, which is remarkably higher than traditional steam methane reforming (SMR) equilibrium H2 yield (70 %). The second developed hybrid sorbent-catalyst (Al-stabilized CaO-NiO) was prepared using limestone acidification coupled with two-step calcination technique. The long-term application of the hybrid catalyst containing 25 wt% NiO led to an average H2 production efficiency of 97.3%, proving its high efficiency in the SESMR process. In summary, the results of this thesis show that the SESR process is as an efficient alternative of traditional steam reforming for production of highly pure H2. The Al-stabilized CaO-NiO hybrid sorbent-catalyst showed an excellent activity over long-term operation, thus confirming its very high potential for use in the SESMR process.

Повний текст джерелаFace à l’augmentation des émissions de gaz à effet de serre, le captage post-combustion du CO2 associé à son stockage est une solution technologique prometteuse. Différentes méthodes sont actuellement développées dont l’adsorption qui fait l’objet de cette étude. Ce travail concerne l’utilisation d’un procédé TSA (Temperature Swing Adsorption) pour le captage post-combustion du CO2. Ce procédé fait appel à un adsorbeur équipé d’un échangeur interne permettant un chauffage (vapeur d’eau) et refroidissement (circulation d’eau) indirects (pas de contact entre le caloporteur et l’adsorbant). Ce travail s’appuie à la fois sur une partie expérimentale et numérique. A partir des premières expériences, la zéolithe 5A a été sélectionnée. Différentes conditions opératoires (composition de l’alimentation, température de désorption, débit de purge, durée du cycle, étapes de pré-refroidissement / pré-chauffage,…) ont alors été testées à partir d’un mélange N2-CO2 afin d’obtenir un compromis optimal entre les critères de performance. D’autres configurations ont ensuite été testées au moyen d’un modèle numérique préalablement validé à partir d’expériences. En phase d’adsorption, la température d’alimentation et la température initiale du lit n’ont que peu d’influence sur les performances de l’adsorbeur. Grâce à une étude paramétrique effectuée pour des cycles, des conditions opératoires optimales, notamment avec une étape de pré-refroidissement, ont été déterminées pour cette application spécifique. Les résultats ainsi obtenus sont tout à fait encourageants puisqu’ils ont permis de mettre en évidence des performances comparables à celles des procédés de référence d’absorption par amine

Повний текст джерелаIn the first part of this study were investigated active materials to electro-oxidize ethanol and acetaldehyde selective for the C2 route (Carbon 2), besides active to electro-oxidize molecular hydrogen, in order to apply into indirect hydrogen fuel cells. In this type of cell, ethanol can be dehydrogenated in the external fuel processor and the products generated in this reaction, containing H2, acetaldehyde and, possibly, unreacted ethanol are used to feed the fuel cell anode. Therefore, the anode electrocatalyst has to be active to electro-oxidize residual ethanol and acetaldehyde, however, it has to catalyze the reaction via C2 route aiming to avoid the species formation that poison the catalyst surface (CO and CHx), in the other words, the C-C bond should remain intact. The bimetallic electrocatalysts were formed by W, Ru and Sn-modified Pt nanoparticles. The reaction products were followed by on-line differential electrochemical mass spectrometry (DEMS) experiments. The results showed that Ru/Pt/C and Sn/Pt/C presented higher overall reaction rate when compared to the other studied materials, however, they were non-selective. On the other hand, W/Pt/C with high W content was more selective to the C2 route, evidenced by the absence of the DEMS signals for molecules with one carbon atom such as CH4 and CO2. Additionally, this material was active and stable for H2 electro-oxidation even in the acetaldehyde presence, what turns it into a potential electrocatalyst for application in the anode of indirect hydrogen fuel cells. In the second part of this work, we investigated conditions and electrocatalysts selective to the C1 route. The ethanol electro-oxidation and its reaction products were investigated by on-line DEMS at room and intermediate temperature. At room, and intermediate temperature (245oC), the electrolytes were aqueous sulfuric acid and solid-state acid (CsH2PO4), respectively. The catalysts investigated were SnOxRuOx-Pt/C and Pt/C. The results of potentiodynamic polarizations at room temperature showed much higher electrocatalytic activity for the SnOxRuOx-Pt/C material, with current efficiency for CO2 formation of 15.6% against 15.2% for Pt/C under stagnant conditions. The reaction residues stripping after the ethanol electro-oxidation, under continuous flow conditions, showed the accumulation of species containing 1 carbon atom (CO and CHx), which are oxidized just at high potentials (ca. 1.0 V) and they cause the obstruction of the active sites. On the other hand, the polarization curves at 245oC showed higher values of current efficiencies (45% for Pt/C for both potentials 0.5 V and 0.8 V against 36% and 50% to SnOxRuOx-Pt/C at 0.5 V and 0.8 V respectively) for the CO2 formation than at ambient condition, however, with similar activities for SnOxRuOx-Pt/C and Pt/C. For both electrocatalysts, in parallel with the electrochemical pathways, heterogeneous chemical catalysis of ethanol decomposition also takes place, producing H2 and CO2, as major products.

Повний текст джерелаThis thesis studies photoelectrochemical CO2 reduction reaction (PEC CO2RR) on p-type semiconductor CuCo2O4 addressing the cocatalytic role of imidazolium based RTILs by scanning photoelectrochemical microscopy (SPECM). CuCo2O4 was studied in different solvent supporting electrolyte systems including: aqueous solution (0.1 M KHCO3 and 0.1 M Na2SO4), binary mixture solution (25 vol.% [C2mim][BF4]/H2O and 25 vol.% [C4mim][BF4]/H2O) and pure RTILs ([C2mim][BF4], [C4mim][BF4]) to explore by SPECM the role of RTILs in CuCo2O4 semiconductor PEC performance. Significantly enhanced photoreduction current under both UV-vis and visible light illumination is reported in 25 vol.% [C2mim][BF4]/H2O solution. Only CO generated from PEC CO2RR was detected using an in-situ detection method based on a home-made dual tip optical fiber-ultramicroelectrode (OF-UME) and from bulk electrolysis under illumination. The formation of CO at potentials more positive than the thermodynamic value clearly points out that direct CO2 reduction on the electrode surface is not the mechanism. A possible reaction scheme for the PEC CO2RR mediated by [C2mim]+ is proposed. Thus, our results have demonstrated for the first time the cocatalytic role of [C2mim]+ for the PEC CO2RR. In addition, electrochemical CO2RR has also been studied on various synthesized transition metal–nitrogen–carbon catalysts (M–N–Cs) by rotating disk electrode. 25%Fe25%Co–N–C exhibited the best performance among the studied M–N–Cs in this thesis. The presence of Co sites in that catalyst provided synergic effect for the generation of distributed Fe-rich microcubes, which act as active sites in electrochemical CO2RR

ZnO nanostructures with different morphology have been successfully and rapidly synthesized in large quantities from a ZnO ceramic bar by CO2 laser direct heating the bar under air ambient. The average growth rate of as-grown ZnO nanostructures exceeds 15 m s-1. The morphology, structure and optical properties of as-grown ZnO nanostructures were further investigated by filed-emission scanning electron microscope (FE-SEM), high-resolution transmission electron microscope (HR-TEM) attached with an energy dispersive X-ray spectroscopy (EDX) system, X-ray diffractometer (XRD) with CuKα as the incident radiation, room-temperature photoluminescence (RT-PL) measurement with He-Cd laser line of 352 nm as an excitation source. Typical FE-SEM images of some different shapes of ZnO nanostructures, such as tubular whiskers, needle-like nanorods, similar tetrapod-like structures, and sword-like rod bundles with sharp tips were found on zinc oxide sheet after exposure to CO2 laser in less than 5s. Structural analysis showed that the as-grown ZnO nanostructures were single-crystal hexagonal wurzite structure in nature with single-phase ZnO and preferentially grown along the [0001] direction. Quantitative analysis of the EDS spectrum for an individual ZnO nanorod showed that the nanorods consist of Zn and O in an atomic composition ratios of approximately 1:1. The room temperature photoluminescence spectra showed a ultra-violet (UV) emission at 3.19 eV and a green emission at 2.5 eV. The UV emission and green emission bands were attributed to near band-edge transition and radial combination of a singly ionized oxygen vacancy with a photo-induced hole, respectively. Finally, we compared our as-grown products with the similar nanostructures in the literature and possible growth process of different ZnO nanostructures was discussed.

Commercially available spherical 13X zeolite was employed as sorbents for CO2 capture from synthetic gas of cylinder of integrated gasification combined cycle(IGCC) power plant and traditional power plant by a dual-bed temperature/vacuum swing adsorption system. The research included two parts as follows: The first part was the selection of the conditions of adsorption and desorption. The adsorption process was conducted at 30°C, 0 % water content. The desorption process was conducted at 120°C desorption temperature, and the desorption time was 20 min. At this ad/desorption conditions, the results showed that the maximum adsorption working capacity (qw) was 157.2 mg/g. And the regenerative working capacity was 130.2 mg/g. The second part was CO2 capture from synthetic gas of cylinder 35% and 15% as CO2 concentration of IGCC and traditional power plant. The condition of synthetic was controlled at 10 LPM (liter per minute) with 35/15% CO2. The results showed that the average working capacity was 115 mg/g and 86.5 mg/g, and the breakthrough time was 50 and 80 minute. The average daily capture rate of 15 and 35%CO2 are 0.79 kg-CO2/day/kg-13X and 1.07 kg-CO2/day/kg-13X, respectively. According to foregoing results, it reveals that the 13X have better adsorption performance of CO2 under IGCC system as compared to traditional power plant.

An integrated gasification combined cycle (IGCC) is a potential electric power technology that turns coal into synthesis gas, which can be burned to generate power. In this study, pressure swing adsorption (PSA) is utilized to capture CO2 from outlet stream of water-gas-shift reactor of IGCC process at nearly 400C with K2CO3-promoted hydrotalcite adsorbent, avoiding energy loss of capturing CO2 at room temperature, and the purified H2 at 400C is sent to gas turbine for generating electrical power. In this study , we first simulate breakthough curve and desorption curve of K2CO3-promoted hydrotalcite, proving the accuracy of our program that we can simulate adsorption and desorption of K2CO3-promoted hydrotalcite correctly.We also simulate 1-bed 5-step process of CO2/H2 separation utilizing 5A zeolite adsorbent, proving the accuracy of our program. Adsorbent K2CO3-promoted hydrotalcite adsorbs CO2 at mid-high temperature and does not adsorb other gases ,such as CO ,H2 and H2O. Non-moisture inlet condition (water is removed before entering PSA process) and moisture condition is studied in simulation at the 1st stage CO2 PSA , and two PSA processes,1-bed 4-step process and 2-bed 6-step process, are studied to separate CO2 from syngas. 1-bed 4-step PSA process generates better purity of CO2 and 2- bed 6-step PSA process have better recovery of CO2.Both of them could achieve above 90% purity and recovery of CO2. For non-moisture inlet ,the best result of 1-bed 4-step process is with CO2 purity of 98.72%and a recovery of 97.96%, and the best result of 2-bed 6-step process is with CO2 purity of 90.15% and a recovery of 98.98%.For moisture inlet ,the best result of 1-bed 4-step process is with CO2 purity of 99.3%,and a recovery of 97.57%,and the best result of 2-bed 6-step process is with CO2 purity of 93.58% and a recovery of 99.23%. The inlet of the 2nd stage H2 PSA coming from part of the top product of the 1st stage CO2 PSA with moisture inlet is reduced to room temperature to remove water content and to perform H2 purification at room temperature.The main compositions of the 2nd stage inlet gas are CO/H2.We use AC5-KS adsorbent and 2-bed 6-step process to separate CO/H2.It can achieve 99% purity and 93 % recovery of H2.

Global warming has become more and more serious, which is caused by greenhouse gases. Cutting down the emission of CO2 has already become the major research target in the world. The main sources of CO2 include the processes of generating electric power and producing hydrogen from natural gas and hydrocarbon. The CO2 which comes from coal is generated by gasifier and the water-gas shift reaction step of the process. Pressure swing adsorption can purify hydrogen with high concentration to be used as energy source and recover carbon dioxide to decrease the impact on the greenhouse effect. Pressure swing adsorption is a cyclic process to separate gas mixtures based on the difference of adsorption capacity of each component on adsorbent. This technology consists of gas adsorption at high pressure and desorption at low pressure to produce high-purity product. This study plans to use dual-bed PSA process to separate high purity hydrogen and to capture CO2 from syngas, which contains CO, CO2 and hydrogen, at room temperature. The optimal operating condition is discussed by varying the operating variables, such as feed pressure, length of adsorber and step time. By PSA process, the goal of energy generation and environmental protection could be achieved at the same time.

Commercially available spherical 13X zeolite was employed as sorbents for CO2 capture from synthetic gas of cylinder and flue gas of gasoline power generator by a dual-bed temperature/vacuum swing adsorption system. Each column of dual-bed system consisted of cylindrical shell and inner column which was designed to pass through the steam fluid or the cooling water to increase or decrease the temperature of the inner column. The research included two parts as follows: The first part was the selection of the optimum sorbent to capture carbon dioxide. The adsorption process was conducted at 30°C, <4 vol% water content and 15% CO2. The results showed that the maximum adsorption working capacity (qw) was 135.8 mg/g. The second part was CO2 capture from synthetic gas of cylinder and flue gas of gasoliner power generator. The condition of synthetic gas was controlled at 10 LPM (liter per minute) with 15% CO2. The flue gas was first introduced into a pretreatment system to remove volatile organic compounds (VOCs), water, oil gas and particles, and then was delivered into a dual-bed adsorption/desorption system, in which the system flow rate was controlled at 10 LPM with a flue gas containing 11.8±0.3% CO2, 1500-4500 ppmv-CH4 VOCs and<1 ppmv SO2. The adsorption process was conducted at 30°C while the desorption process was conducted at 100°C, 0.6 bar and 20 min. The results indicated that after 50 cycles, the average qw, the AI (adsorption index) and the CO2 removal efficiency (RE) respectively reached 85.1 mg/g, 92.4% and 99.6% with synthetic gas and 74.5 mg/g, 75.1% and 99.1% with flue gas. This reveals that the 13X zeolite with dual-bed temperature/vacuum swing system has feasibility on CO2 capture from flue gas of gasoline power generator.
