摘　　要：探讨了以菜籽油为原料,与甲醇反应,加入KF/CaO作为催化剂,经过超声波反应制备生物柴油的工艺条件,考察了超声波频率、醇油物质的量的配比、催化剂用量、反应时间等条件对反应的影响,实验结果表明该反应最佳的条件为:超声波频率为30KHz,醇油物质的量的配比为7:1,催化剂投加量为2.5%,反应时间为30min,产率达92.98%。对所得生物柴油的主要性能指标符合德国现阶段的生物柴油标准。In this paper, rapeseed wave with the addition of KF/CaO as ultrasonic frequency, the molar ratio oil as raw in solid base ca of methanol aterial, reacted with methanol under ultrasonic talyst, then the bio - diesel was obtained. The o rapeseed the amount of catalyst and the reaction time were investigated. We found out optimum reaction conditions： the ultrasonic frequency was 30KHz, the molar ratio of methanol to rapeseed oil was 7 ： 1, the quality ratio of catalyst to rapeseed oil was 2.5%, the reactive time was 30 minutes, and the yield was up to 92.98%. Then the performance of the obtained bio- diesel was investigated, which reaches the current bio- diesel standards in Germany.
