摘　　要：糠醛常压气相加氢制糠醇催化剂ＣｕＣｒＫ／γ┐Ａｌ２Ｏ３殷恒波申延明高丽萍赵秉乾张振祥（沈阳化工学院化工系，沈阳１１００２１）关键词铜，铬，钾，氧化铝，负载型催化剂，糠醛加氢，糠醇糠醛加氢制糠醇工艺分中高压（１８０～２２０℃，６．０～１２．０ＭＰａ）液...CuCrK/ γ Al 2O 3 catalysts ( φ 2 5×2 5￣3 5 mm) were prepared by impregnation method. The conversion of furfural was more than 0 985 and the selectivity for furfuryl alcohol more than 0 985 under the reaction duration 984 h, corresponding to the loading amount of 0 08 g furfural per gram catalyst per hour, temperature 130￣209℃ and atmospheric pressure. The reason for deactivation was that polymer covered the catalyst surface. During oxidizing regeneration, oxygen and polymer reacted to form furfural and furfuryl alcohol below 200℃ and carbon dioxide and water in the range of 200￣320℃. Most Cu 0 in the catalyst was not oxidized.
