| 제목 | Characterization and Testing of Copper Modified Catalysts for WGS Reaction |
| 초록 | The water gas shift (WGS) reaction is crucial in producing pure hydrogen. 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. 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. |
