Available in PDF, EPUB and Kindle. Book excerpt: Hydrogen is one of the most suitable energy sources from both technological and environmental perspectives for the next century, especially in the context of a sustainable global energy economy. The most common industrial process to produce high-purity (99.99+ mol%) hydrogen is to reform natural gas by a catalytic reaction with steam at a high temperature. Conventional steam-methane reforming (SMR) contributed to approximately 2.4 billion standard cubic feet per day (SCFD) of hydrogen production in the US. By 1998, the growth of SMR-produced hydrogen in the US is expected to reach 3.4 billion SCFD, with the increased demand attributed to hydrogen's use in reformulated gasolines required by the Clean Air Act. The goal of this work is to develop an even more efficient process for reforming steam and methane to hydrogen product than the conventional SMR process. The application of Sorption Enhanced Reaction (SER) technology to SMR has the potential to markedly reduce the cost of hydrogen through lower capital and energy requirements. The development of a more cost-effective route to hydrogen production based on natural gas as the primary energy source will accelerate the transition to a more hydrogen-based economy in the future. The paper describes the process, which includes a sorbent for CO2 removal, and the various tasks involved in its development.

Available in PDF, EPUB and Kindle. Book excerpt: At the beginning of the twenty-firstst century, separation processes presented a comprehensive application of the major operations performed by various industries, such as chemical, food, environmental, and biotechnology. Sorption, one of the preferred separation processes because of its effectiveness at different interfaces, has caught the attention of many scientists. This book is aimed at gaining a general knowledge of sorption and a number of extremely important applications, as well as recognizing its functions and paramount importance in chemical and biochemical plants, including environmental treatment. Moreover, progress in the phenomenon is highlighted in this book. To help provide instruction in the important sorption processes, we have chosen authors who have extensive industrial and academic experience in closing the gap between theory and practice. Crucial progress in the theoretical information section of sorption has been achieved, mainly through the development of new techniques that examine the usage of various sorbents, including nanomaterials for the removal of various pollutants. We have subdivided the book into several sections, one of which is focused on applications of the sorption process, which presents real results of the recent studies and gives a source of up-to-date literature. The relationship between the sorption process and isotherm and kinetics modeling is analyzed in another chapter. This book will be a reference book for those who are interested in sorption techniques from various industries.

This book was released on 2010-01-01 with total page 211 pages. Available in PDF, EPUB and Kindle. Book excerpt: An emerging area of research and development called Sorption Enhanced Reaction (SER) has generated much interest during the last decade in the development of (a) new reversible chemisorbents for carbon dioxide in presence of steam and (b) process schemes using those materials for production of fuel-cell grade H2 from (i) natural gas by low temperature endothermic steam-methane reforming (SMR) reaction, and (ii) synthesis gas by exothermic water gas shift (WGS) reaction, with or without simultaneous production of a by-product CO2 stream for subsequent sequestration. The research is primarily driven by the advent of the hydrogen economy and the concern of global warming and ocean acidification by CO2 emission to the atmosphere . The SER concepts are based on the well-known Le Chatelier s principle that the thermodynamic limitations (product purity and conversion) of an equilibrium-controlled reaction (catalytic or otherwise) can be circumvented by carrying out the reaction in presence of a sorbent which selectively removes a reaction product from the reaction zone, thereby increasing the conversion of reactants to products and the rate of the forward reaction. The two key chemical reactions are: SMR Reaction (Endothermic): CH4 + H2O ? CO + 3 H2, WGS Reaction (Exothermic): CO + H2O ? CO2 + H2, Both reactions are equilibrium-controlled and in situ removal of CO2 from the reaction zone at the reaction conditions will benefit production of H2 in many different ways. The thermodynamics of SMR reaction is favored at higher temperatures and conventional SMR reactors are operated above 800 oC requiring expensive alloyed steel reactors. The SER concept permits drastic lowering of the reaction temperature to 450 550 oC without sacrificing the conversion of CH4 to H2, thus significantly reducing the capital and operating costs of the reactor. It also enhances the rates of the forward reactions. Furthermore, the concept (i) minimizes or eliminates carbon formation and catalyst deactivation, (ii) increases H2 product purity, and (iii) decreases the footprint of the plant by combining the reaction and product purification steps in a single unit. The thermodynamics of the WGS reaction is favored at the lower temperatures. However, conventional WGS reactors are operated in the temperature range of 250 400 oC in order to achieve an acceptable rate of reaction. The SER concept enhances the rate of WGS reaction at lower temperatures and improves the conversion of CO to H2 and product purity. It also combines the reaction and the product purification steps in a single unit. This compendium contains six comprehensive articles describing CO2 chemisorbents and SER process concepts for H2 production. They were written by six eminent research groups around the world who have direct and extensive expertise on these subjects. The following table gives the author names, affiliations, and the titles of the articles. The CO2 chemisorbents employed in these studies include materials which undergo bulk chemical reactions with CO2 as well as materials where the CO2 chemisorption is limited to the surface. The SER processes involve a multitude of variations including pressure swing adsorption (PSA) schemes, thermal swing adsorption (TSA) schemes, combinations thereof, fixed-bed and fluidized-bed operations, continuous or semi-batch operations, etc. Experimental as well as model simulations of the process performances are also reported by the authors. The paper by Rodrigues, Xiu, Li, Grande, and Oliveira from the University of Porto, Portugal describes the simulated performance of two different SER concepts for production of H2 by SMR which employ the principles of PSA and commercial hydrotalcites modified by potassium and cesium carbonates as CO2 sorbents. The PSA concepts use (i) purge with 10% H2 in N2 for regeneration and (ii) subsections with different sorbent/catalyst ratio and operating temperatures. The paper by He and Chen from the Norwegian University of Science and Technology, Trondheim, Norway provides an extensive review of CO2 acceptors for use in SER-SMR concepts for H2 production. The materials include CaO/dolomite, Li2ZrO3, Na2ZrO3 among others. The key topics include thermodynamics and kinetics of SER process using these materials, stability of the sorbents, as well as basic SER process concepts. The paper by Harrison from Louisiana State University, Baton Rouge, LA, U.S.A. reviews various SER-SMR process designs using CaO as the CO2 sorbent. The concept can lower the SMR reaction temperature by ~200 oC compared to the conventional reaction temperature. The article by Beaver, Lee, Caram, and Sircar from the Lehigh University, Bethlehem, PA, U.S.A. reviews their recent works on a novel rapid thermal swing sorption enhanced reaction concepts for (i) production of fuel-cell grade H2 by low temperature SMR and (ii) simultaneous production of fuel-cell grade H2 and pure, compressed CO2 for subsequent sequestration from synthesis gas produced by coal gasification. Simulated process performance of these concepts are presented using K2CO3 promoted hydrotalcite and Na2O promoted alumina as CO2 sorbents. The paper by Lee, Yoon, and Baek from the Korea Institute of Energy Research, Daejeon, Korea presents model parametric studies of process design variables for production of H2 using a SER-SMR concept employing CaO as the CO2 sorbent. The article by Barelli, Bidini, and Gallorini from the University of Perugia, Italy describes a model analysis of a thermo-fluid dynamic model of a fixed-bed SER-SMR reactor for H2 production and its experimental verification. We believe that the present compilation provides a state of the art research status for the subject and will form an excellent starting point for future research. We are grateful to the authors for their kind and timely participation and contributions for making this publication a reality. We also thank Dr. S. G. Pandalai, Managing Editor of Research Signpost for inviting us to prepare this special review book and providing us with all the help for its publication.

This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2020 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
