Study on the Structure and Catalytic Property of Fe_2O_3/ZrO_2 Catalysts

FezO3/ZrO2 catalysts prepared by impregnation and coprecipitation methods were used for catalytic hydrogenation of CO. It was shown that the structures,reduction behaviour of iron species, and catalytic properties of the catalysts were markedly affected by the preparation methods. For the Fe2O3/ZrO2 catalyst prepared by impregnation method, the F-T catalytic activity and the selectivity to light olefins were much higher than those of the correspond in g catalyst prepared by coprecipitation method, the formation of methane was suppressed and the selectivity to light olefins were enhanced.
