摘　　要：本文探讨了10％WO_3含量的W-Si系催化剂中助催化剂对丙烯歧化催化剂的活性、选择性和稳定性的影响,并从催化剂的酸度、XRD和BET等诸方法来分析探讨助剂的作用。本文还讨论了反应温度、压力和空速等工艺条件对反应的影响。The effects of promoter on the activity, selectivity and stability of W-Si series propene for disproportionation catalyst containing 10% WO_3 were discussed. The promoter action on the catalyst were well explained by the data of catalyst acidity, XRD and BET data. The effects of temperature, pressure and space velocity on the reaction activity were also studied.
