Performance of spinel ferrite catalysts supported on mesoporous Al2O3 for high temperature water-gas shift reaction |
| 초록 |
The present study focuses on the use of spinel ferrite (MFe2O4) catalysts supported on mesoporous alumina for the high temperature water-gas shift (WGS) reaction. High temperature WGS reaction has been carried out at a gas hourly space velocity of 41,821 h-1 over MFe2O4 catalysts prepared by the sol-gel method using a non-ionic template. Ni, Co, Fe, or Cu were employed as active metal for the target reaction in this study. Among these catalysts, copper ferrite supported on mesoporous alumina (CuFe2O4−MA) exhibited outstanding performance. The reason for the higher activity of CuFe2O4−MA might be a promotional effect of Cu on the reduction of hematite to magnetite, shifting it to a lower temperature, and better dispersion of CuO over the mesoporous alumina support. |
