摘　　要：Cu-CrCa系列复合氧化物催化剂用于糠醛液相加氢制糠醇已有较多报道。已知的气相加氢催化剂有低铬铜系复合氧化物,Cu/SiO_2、Cu/Al_2O_3等。我们发现CuCr/γ-Al_2O_3用于常压糠醛气相加氢制糠醇时负荷量大,活性组分用量少,加氢转化率高,选择性好。本文讨论催化剂结构对加氢反应的影响。The influence of the structure of the CuCr/γ-Al_2O_3 catalyst on gas phase hydrogenation of furfural to furfuryl alcohol at atmosphere pressure has been studied by XRD, XPS spectra and TPR technique. It is found that Cu and Cr appeared widely distributed in the surface of γ-Al_2O_3 support and converted into CuCrO_4 when their contents in the catalyst were high. This very CuCrO_4 increases the hydrogenation activity and selectivity of the catalyst.
