第30卷第4期 selectivity on the surface of ZrO2 catalyst were low. After Cu
modification, the ethanol conversion and n-butanol selectivity were significantly increased. After further
modification with alkali metal K,the ethanol conversion decreased slighdy,while the n-butanol selectivity
was further improved. The introduction of Cu promoted the dehydrogenation performance of ethanol, while
the introduction of K enhanced the surface alkaline strength of the catalyst, improved the amount of catalyst
alkali, promoted the condensation reaction, and improved the selectivity of n-butanol. In the 100 h reaction
process, the ethanol conversion of KCuZrO2 catalyst was maintained at about 86% , while the selectivity of
n-butanol was about 70%.
