摘　　要：制备了一种新型、无毒Cu-Zn-Ca／γ-Al2O3配合物催化剂。采用固定床反应器，进行糠醛常压气相催化加氢反应，考察反应温度、催化剂组成、空速和氢醛比等因素的影响。结果表明，在508K、空速0.32h^-1、还原温度保持（493-513）K、活化6h和氢醛物质的量比为10：1条件下，糠醛转化率达到98.90％，2-甲基呋喃选择性达92.30％，2-甲基呋喃收率达91.28％。作为一种新型的无Cr催化剂，无毒，无污染，可代替Cu-Cr催化剂用于糠醛加氢过程，高活性和高选择性地制取2-甲基呋喃。A new harmless Cu-Zn-Ca/γ-Al2O3 complex catalyst was prepared. The catalytic vapor-phase hydrogenation of fuffural to 2-methylfuran was studied in a fixed bed reactor, and the influential factors, such as reaction temperature, composition of catalyst, LHSV, hydrogena-to-furfural mole ratio, grain size of the catalyst, on conversion, selectivity and yield were investigated. Selectivity of over 99%, and yield of 97% were obtained for 2-methylfuran under the following condition： 508 K, LHSV 0.32 h^-1 , reduction temperature 493-513 K, activation for 6 h, n（hydrogen）： n（furfural） = 10： 1. The catalyst, with high activity and excellent selectivity, could be a substitute for Cu-Cr catalysts for production of 2-methylfuran.
