제목 Studies on Characteristics of Cu Modified Catalyst for Water Gas Shift
초록 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. A series of Cu modified ceria-zirconia mixed oxides was prepared, characterized, and tested for the WGS reaction. The catalyst was prepared by an impregnation method, and were characterized by N2 physisorption, CO chemisorption and XRD. It was found that Cu/CexZr1-xO2 catalyst showed higher activity and stability than the other catalyst for WGS reaction.
