【摘要】 研究了常压下糠醛气相加氢制糠醇催化剂 Cu Cr/γ-Al2O3的结构,以及结构对加氢活性的影响;随催化剂中 Cu,Cr 含量的增多,Cu,Cr 在载体γ-Al2O3上由高度分散且和γ-Al2O3有作用的 CuO,CrO42-结构逐步转向 CuCrO4的结构.催化剂母体中,CuCrO4的生成提高了还原后的催化剂对糠醛加氢制糠醇的活性.

【Abstract】 In this paper,the structure of Cu Cr/γ-A12O3 catalysts and the influence of the struc- ture of catalysts on activities of furfural hydrogenation to furfuryl alcohol was studied. With the advance of Cu Cr contents,Cu Cr which had high degree distribution and acted with γ-Al2O3 turned from CuO,CrO4-2 into CuCrO4 gradually.CuCrO4 formed in catalyst parents enhanced catalyst activities.
