Abstract

Abstract

Co_x-MoS₃-K_y/γ-Al₂O₃catalyst was prepared by microwave-assisted impregnation and used for higher alcohols synthesis from CO hydrogenation; the effect of K or Co content on its catalytic performance was investigated. The results showed that appropriate amounts of K and Co can promote the formation of K-Mo-S and Co-Mo-S phases, which enhances the catalytic activity of CO hydrogenation and prevents active components from agglomeration and blocking the support pores. The optimal mol ratios of K/Mo and Co/Mo that are beneficial for the formation of higher alcohols are 1.0 and 0.2, respectively.
