| Abstract: | Summary The effect of ceria addition on the performance of 10 wt.% Co catalysts supported on SiO2 and Al2O3 for Fischer-Tropsch synthesis
has been investigated. The catalysts were prepared by impregnation method and characterized by X-ray diffraction technique.
The catalytic tests (P = 1 atm, T = 488 K, H2/CO = 2, GHSV=1800 h-1) indicate that with addition of ceria, significant changes
in CO conversion and hydrocarbon selectivities are observed. Also, the experiments show that the performance of 10 wt.% Co-CeO2/Al2O3
depends on the ceria concentration as well as on the pre-calcination temperature. |
