【Abstract】 Effect of Mn and Zn on catalytic properties of KFe/ZSM48 in CO hydrogenation were investigated The results show that both Zn and Mn favour carbon monoxide conversion and low olefins formation There is a synergetic role between Zn and Mn which makes Zn-Mn-K-Fe/ZSM48 has higher activity and selectivity to low olefins than Zn-K-Fe/ZSM48 and Mn-K-Fe/ZSM48 The results of TPR indicate that Zn and Mn have great influence on reduction property of K-Fe/ZSM48, which may be the important factor resulting in a better catalytic behaviors更多还原
