Progress in Energy and Combustion Science

In this work, advanced technologies concerning warm gas carbon capture and hydrogen production from carbon-based fuels are reviewed, with a primary focus on the elevated-temperature pressure swing adsorption process coupled with the water gas shift reaction and in-situ CO2 adsorption. Key progress in the development of adsorption kinetic models, study of adsorption mechanisms, synthesis of efficient CO2 adsorbents, design and process optimization of adsorption/desorption reactors, and integration of purification systems, as well as major challenges and perspectives for the fundamental study and pilot-scale system development are discussed. This review provides a theoretical basis for the scaling-up of the next carbon capture system, and has scientific value and strategic significance for alleviating carbon emission pressure, developing hydrogen fuel cell energy system, and reducing energy consumption of hydrogen production in coal processing industries.
