摘要/Abstract

摘要： 采用浸渍法制备Cu-ZnO-Cr₂O₃/SiO₂ 催化剂, 考察了反应条件和催化剂的制备条件对仲丁醇脱氢活性和选择性的影响. 借助XRD, TPD, TPR和BET等手段对催化剂进行表征，结果表明，催化剂的焙烧温度、还原温度、还原时间和载体的预处理对仲丁醇的转化率和甲乙酮的选择性均有较大影响. 通过实验获得了最佳的反应和催化剂制备条件.

Abstract: The Cu-ZnO-Cr₂O₃/SiO₂ catalyst was pre pared by the impregnation method. The effe cts of the reaction conditions and the catalysts preparation conditions on the d ehydrogenation of 2-butanol and the selectivity for MEK were studied. Based upo n the characterization by means of XRD, TPR, EPR and BET, the optimal conditio ns of the reaction and the preparation of catalysts were suggested.

Key words: dehydrogenation, Cu-ZnO-Cr₂O₃/SiO₂ ca talysts, 2-butanol
