Development of High Performance Catalyst for Low Temperature Water Gas Shift Reaction |
| 초록 |
Water Gas Shift (WGS) reaction is one of the key catalytic stages in the fuel processor for a hydrogen station and a fuel cell powered vehicle application. The commercial low temperature shift (LTS) catalyst (Cu-Zn/Al2O3), though highly active at low temperature, was unsuitable for commercialized applications because of the large size, the heavy weight and the rapid deactivation tendency of the LTS catalyst under severe conditions. The WGS reaction over Pt based catalysts were performed to develope a high performance LTS catalyst. The catalysts were prepared by an incipient wetness method, and were characterized by N2 physisorption, CO chemisorption, XRD, SEM and TPR. It was found that Pt based catalyst supported on CeO2 showed higher activity and stability than the other catalysts under the tested conditions. |
