摘　　要：Mn改性Cu Zn Al催化剂是糠醛气相加氢制糠醇的有效催化剂 ,在较温和的条件下 (氢醛比 :9;糠醛液体空速 :1 0h-1;反应温度 :130℃ ) ,糠醛转化率为 99 8% ,糠醇选择性 97 7%。K助剂的浸入可进一步提高糠醇的选择性。工业侧线运行结果表明 ,Cu ZnMn modified Cu Zn Al catalyst is an active one for gas phase pydrogenation of furfural to furfuyl alcohol.When Mn is added as a promoter,the conversion of furfural is about 99 8% with a selectivity for furfuryl alcohol about 97 7% under the condition of H 2/F=9,GHSV of liquid furfural=1 0h -1 and T =130℃.Different precipitants has different effects on the catalytic activity.Furthermore,promoter K can further improve the selectivity for furfuryl alcohol.
