Book Description
This book investigates the development of sorption enhanced reaction processes (SERPs) with detailed modelling and simulation, design and operation of units. SERPs are processes intensified by combining adsorption and reaction, reaction and membranes or reaction/adsorption/membranes in a single unit in order to overcome thermodynamic limitations of conversion in reversible reactions. The focus here is on gas phase and liquid phase processes involving different technologies, including pressure swing adsorptive reactors, membrane reactors and simulated moving bed reactors. Emphasis is also given to presenting data and practical applications of SERP products.Sorption Enhanced Reaction Processes provides undergraduate and graduate students of chemistry and chemical engineering, researchers and industrial engineers with a clear path towards process development of SERP, whatever the area of application.

Book Description
Energy security and climate change are two common challenges in the coming decades. The demand for energy is increasing. The CO[subscript 2] in the atmosphere has increased to almost 400ppm, and it is mainly from energy usage. How to deal with energy-related CO[subscript 2] emissions with the increasing demand for energy is becoming more crucial. Carbon capture and sequestration during energy production is an efficient way to guarantee enough energy supply with a smaller carbon footprint. One unique technique is using in-situ CO [subscript 2] capture technology, which uses a sorbent to capture CO[subscript 2] directly in the reactor. CO[subscript 2] is removed quickly as it forms by the sorbent, which can change the equilibrium to promote more energetic production. This technology has great potential to lower CO[subscript 2] emissions and get higher energy production simultaneously. A new concept of sorption enhanced steam hydrogasification reaction (SE-SHR) is the topic of this thesis. It combines sorption enhanced principles with the steam hydrogasification reaction (SHR). It was found that the addition of sorbent enhanced the CO [subscript 2] removal and increased the production of H[subscript 2] and CH[subscript 4] . Particularly, the amount of H[subscript 2] was increased dramatically. It was found that the increase in H[subscript 2] was enough to recycle when the CaO/C molar ratio was over 0.29. The sorption enhanced performance was also evaluated by varying other parameters including H[subscript 2] /C and Steam/C molar ratio, gasification temperature and sorbent particle size. A study of the kinetics of the system showed that higher gasification temperature favored faster formation rates of CO[subscript 2] , CO and CH[subscript 4] during both SHR and SE-SHR. The formation rates of CO[subscript 2] and CO at 650°C, 700°C and 750°C were much lower during SE-SHR. Several configurations based on SE-SHR for the production of Fischer Tropsch fuel and synthetic natural gas were developed and evaluated. The optimum gasification condition (H[subscript 2] /C-Steam/C) for Fischer Tropsch fuel production using SE-SHR based process was found to be 1.59-2.78. This process had lower total CO[subscript 2] emissions with higher fuel yield compared to the optimum SHR based process. SE-SHR-Methanation based process for SNG production with the optimum gasification condition (H [subscript 2] /C-Steam/C) of 1.08-2.22 had the highest CH[subscript 2] % and near zero CO[subscript 2] % in the final gas product.

Book Description
The goal of this project is to evaluate the extensive feasibility of a novel concept called Thermal Swing Sorption Enhanced Reaction (TSSER) process to simultaneously produce H2 and CO2 as a single unit operation in a sorber-reactor. The successful demonstration of the potential feasibility of the TSSER concept implies that it is worth pursuing further development of the idea. This can be done by more extensive evaluation of the basic sorptive properties of the CO2 chemisorbents at realistic high pressures and by continuing the experimental and theoretical study of the TSSER process. This will allow us to substantiate the assumptions made during the preliminary design and evaluation of the process and firm up the initial conclusions. The task performed under this project consists of (i) retrofitting an existing single column sorption apparatus for measurement of high pressure CO2 sorption characteristics, (ii) measurement of high pressure CO2 chemisorption equilibria, kinetics and sorption-desorption column dynamic characteristics under the conditions of thermal swing operation of the TSSER process, (iii) experimental evaluation of the individual steps of the TSSER process (iv) development of extended mathematical model for simulating cyclic continuous operation of TSSER to aid in process scale-up and for guiding future work, (v) simulate and test SER concept using realistic syngas composition, (vi) extensive demonstration of the thermal stability of sorbents using a TGA apparatus, (vii) investigation of the surfaces of the adsorbents and adsorbed CO2, and (viii) test the effects of sulfur compounds found in syngas on the CO2 sorbents.

Book Description
This book approaches the energy science sub-field carbon capture with an interdisciplinary discussion based upon fundamental chemical concepts ranging from thermodynamics, combustion, kinetics, mass transfer, material properties, and the relationship between the chemistry and process of carbon capture technologies. Energy science itself is a broad field that spans many disciplines -- policy, mathematics, physical chemistry, chemical engineering, geology, materials science and mineralogy -- and the author has selected the material, as well as end-of-chapter problems and policy discussions, that provide the necessary tools to interested students.

Book Description
Stabilizing atmospheric concentrations of CO2 has become a significant focus worldwide as environmental concern continues to increase and carbon-based fuel sources continue to play a significant role in energy generation. For this reason, mitigation actions are needed to stabilize the atmospheric CO2 concentration at 500 parts per million. The International Energy Agency has suggested the use of carbon-neutral renewable energy sources such as biomass, carbon-free sources such as hydrogen, and carbon capture and storage as effective CO2 reduction methods. These technologies have the potential to reduce anthropogenic CO2 during the transition towards a low-carbon energy system. This study focused on discovering a combination of these approaches that uses innovative sorption processes to achieve lower overall carbon emissions. The objectives of this work were to study the fundamental structure-function relationships for organic and inorganic synthetic materials in sorption application systems and analyze the common characteristics shared between adsorption, absorption, and ion exchange for the extraction of molecules and ions from aqueous solutions. The research also investigated applying sorption operations in sustainable processes to improve efficiency, reduce energy, and subsequently, reduce costs through process intensification by inducing reactions simultaneously with separation. The merit of this process is attributed to efficient energy and material utilization.
