The double mesoporous Co-based catalysts were prepared by incipient-wetness impregnation method, which were characterized by the technology of XRD, BET, SEM and H₂-TPR. And the influences of reduction temperature on the structure and performance of the catalysts in Fischer-Tropsch were investigated. The result showed that with the increase of reduction temperature, the active sites of catalysts increased, and the activity increased. After the activity reached a certain level, it began to decline. And the methane selectivity increased with the increase of reduction temperature. The related reactive performance might be due to the cobalt oxides on the surface of catalysts formed in the reaction, which made the water gas shift reaction become active, and the hydrocarbon products moved to low hydrocarbons.
