Sorption-Enhanced Fuel Conversion

This chapter deals with the advancements in enhanced fuel conversion by sorbents. Particular attention is devoted to sorbent application in power plants for H2 production and/or CO2 capture using both natural gas and coal as feedstock. Among several enhanced fuel conversion processes, the most investigated are the Sorption-Enhanced Reforming (SER) process and Sorption-Enhanced Water Gas Shift (SEWGS). The sorbent is the most important component in an enhanced reactor since it determines the reactor design and the performance of the process. The chapter presents the advancement in sorbent development for SERP and SEWGS. For sorption processes, the difficult part is typically not the adsorption step where one or more components are removed from a gas stream but instead how to regenerate the sorbent economically and recover the adsorbed component(s). The chapter describes the development and application of sorption-enhanced reaction processes to power plants with low CO2 emissions
