In this work, an electrolytic process was introduced for coupled regeneration of potassium carbonate (K2CO3) solution and water electrolysis by using an anion exchange membrane cell. The process made the CO2 separation from O2 much easier with respect to the existing cationic exchange membrane process. The solution of K2CO3 was used in the cathode chamber to simulate the solution after absorbing CO2. The solution of sulfuric acid (0.1 mol/L H2SO4) was charged in the anode chamber. The feasibility of the process was discussed. The effects of various operation parameters, including temperature, current density, and electrolysis time, were studied. The results indicate that both the yield rate of CO2 and the current efficiency increase initially and decrease afterward with temperature. The yield rate of CO2 increases while the current efficiency decreases with the current density. A low current density can reduce the energy consumption for producing the same amount of CO2. The processes using anion exchange membrane electrolysis can regenerate the absorbent solution to achieve 89% current efficiency, and the simultaneous production of three pure gases, CO2, H2, and O2, makes this method promising.

Fundamental study and industrial application of ion exchange membranes started over half a century ago. Through ongoing research and development, ion exchange membrane technology is now applied to many fields and contributes to the improvement of our standard of living. Ion Exchange Membranes, 2nd edition states the ion exchange membrane technology from the standpoint of fundamentals and applications. It discusses not only various phenomena exhibited by membranes but also their applications in many fields with economical evaluations. This second edition is updated and revised, featuring ten expanded chapters. New to this edition is a computer simulation program of ion-exchange membrane electrodialysis for water desalination that provides a guideline for designing, manufacturing and operating a practical-scale electrodialyzer. Meant to replace experiments, this program will be an important asset to those with time and monetary budgets.

The recycling of atmospheric molecules for use as fuels and chemicals is a goal which can only be achieved through a deeper understanding of catalytic processes, particularly electrocatalysis whereby redox transformations can be interfaced with solar or nuclear energy input. Carbon dioxide is a prototypical small molecule in many regards since it is chemically inert. In addition, because of the likely role of carbon dioxide in global temperature cycles, it will be imperative in the future to regulate the output from industrial processes. The purpose of this book is to present a unified discussion of the carbon dioxide chemistry which is necessary for the understanding and design of electrochemically-driven processes for the reduction of carbon dioxide and to provide an impetus for the further development of electrocatalytic carbon dioxide chemistry.

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.
