Sorption-Enhanced Water-Gas Shift Reaction for Synthesis Gas Production from Pure CO: Investigation of Sorption Parameters and Reactor Configurations

A sorption-enhanced water-gas shift (SEWGS) system providing CO2-free synthesis gas (CO + H2) for jet fuel production from pure CO was studied. The (WGS) reaction catalyzed by a commercial Cu/ZnO/Al2O3 catalyst and carried out with in-situ CO2 removal on 20 wt% potassium-promoted hydrotalcite-derived sorbent. Catalyst activity investigated in fixed bed tubular reactor. Different sorbent materials treatments were characterized chemisorption among other analysis methods to choose suitable Cyclic breakthrough tests an isothermal packed microchannel reactor (PBMR) performed at significantly lower modified residence times than those reported literature. parameter study gave insight into the effect of pressure, adsorption feed composition, desorption conditions, as well configuration delay adsorbed amount CO2. Special attention paid steam content. significance water during confirmed existence different sites. Various packing concepts showed that interaction relatively fast slow kinetics plays key role SEWGS process design low time conditions.
