本文主要介绍了间歇式反应釜中糠醛在Cu-Zn/γAl2 O3催化剂条件下在不同温度、时间、糠醛浓度和溶剂体系中的催化加氢制糠醇，从糠醛转化率和糠醇选择性两方面对加氢效果进行比较。通过实验，我们得到了糠醛加氢制糠醇的最佳工艺条件为反应温度为160℃、反应时间为3 h、催化剂用量为糠醛的7wt%、糠醛浓度为5wt%~25wt%、溶剂为甲苯时，糠醛的转化率和糠醇的选择性最好，分别为99%和98%。

Using Cu-Zn/γAl2 O3 as catalyst, the catalytic hydrogenation of furfural to furfuryl alcohol was de-scribed at different temperatures, time, furfural concentration and solvent system. The different hydrogenation effects were compared at furfural conversion and furfuryl alcohol selectivity. Through experiments, the optimum conditions were determined for hydrogenation of furfural as a reaction temperature of 160 ℃, reaction time 3h, the amount of catalyst is furfural 7wt%, furfural concentration of 5wt% ~25wt%. When the solvent was toluene, the furfural con-version and furfuryl alcohol selectivity were respectively up to99% and 98%.
