제목 Studies on the water gas shift reaction over ceria-supported precious metals
초록 Water Gas Shift (WGS) reaction is one of the key catalytic stages in a fuel processor and hydrogen station. The commercial low temperature shift (LTS) catalyst (Cu-Zn/Al2O3), though highly active at low temperature, was unsuitable for commercialized applications because of the rapid deactivation tendency under severe conditions. Also, the Cu-Zn/Al2O3 catalyst can not be used at temperatures above about 250℃, which further limits their utility. The WGS reaction over ceria based catalysts was investigated to develop an alternate commercial Cu-Zn/Al2O3 catalyst. The catalyst was prepared by an impregnation method, and were characterized by N2 physisorption, CO chemisorption and XRD. It was found that Cu-Mo/CeO2 catalyst showed higher activity and stability than the commercial LTS catalyst for WGS reaction.
