摘　　要：采用化学还原法制备了CoNiB非晶态合金催化剂,并用于糠醛液相加氢制糠醇反应。考察了Ni/Co摩尔比,NaBH4滴加速率等催化剂制备条件对催化性能的影响,以及反应压力、反应时间、反应温度等反应条件对糠醛转化率和糠醇选择性的影响。结果表明:最佳的催化剂制备条件是Ni/Co摩尔比为5/5,NaBH4滴加速率为2.6mL·min-1;最佳的反应条件为反应压力2MPa,反应时间3h,反应温度80℃。在此条件下糠醛的转化率为46.2%,糠醇的选择性为90.4%。CoNiB amorphous alloy catalysts were prepared by chemical reduction and were used for catalyzing liquid phase hydrogenation of furfural （FFR） to furfuryl alcohol （FFA）. The effects of Ni/Co molar ratio, NaBH4 adding rate on the properties of the catalyst were investigated, and the effects of reaction pressure, reaction time, reaction temperature on the conversion of furfural and selectivity to furfuryl alcohol were studied in detail. The results indicated that under Ni/Co molar ratio 5/5, NaBH4 adding rate 2.6mL·min-1 , reaction pressure 2MPa, reaction time 3h, reaction temperature 80℃, the conversion of furfural and selectivity to furfuryl alcohol is 46.2% and 90.4%.
