采用浸渍法制备了活性炭负载KOH固体碱催化剂，考察了它们在三醋酸甘油酯与甲醇酯交换反应中的催化性能，及时间、温度、催化剂用量、醇酯摩尔比等因素对酯交换反应的影响。结果表明，当醇酯比为9∶1，催化剂用量为0.3g（三醋酸甘油酯为0.02mol），KOH浸渍液浓度为20.0wt%，反应温度为65℃，反应1.0h，三醋酸甘油酯转化率可达到94.7%。该工艺操作简单，催化剂可以回收，过程无三废污染。

Transesteriifcation of glycerol triacetate and methanol catalyed by KOH supported on activated carbon was studied. The catalyst was prepared by impregnation and had a high catalysis activity. Effects of some factors on the transesteriifcation were inves-tigated systematically and reaction conditions were optimized. The optimized reaction conditions on the catalyst were:molar ratio of methanol to oil 9:1, the amount of catalyst 0.3g(the amount of glycerol triacetate 0.02mol), the consistency of KOH 20.0wt%, reac-tion temperature 65℃and reaction time 1.0h, under these conditions the conversion of biodiesel reached 94.7%. The new technology featured simplicity, reusable catalyst, zero pollution.
