摘　　要：以菜籽油和甲醇为反应原料,以KNO3/Al2O3为催化剂,采用超声波法制备生物柴油,考察了超声波频率、醇油物质的量比、催化剂用量等条件对反应的影响。试验结果表明,该反应的最佳条件:超声波频率为30kHz,醇油物质的量比为7∶1,催化剂用量为菜籽油质量的2.0%。在此条件下,生物柴油产率为94%。所得生物柴油的主要性能指标均符合德国的生物柴油标准。In this paper, with rapeseed oil as raw material, have the reaction with methanol under ultrasonic wave with the addition of KNO3/Al2O3 as solid base catalyst, then the bio-diesel was obtained. The ultrasonic frequency, the molar ratio of methanol to rapeseed oil and the dosage of catalyst were investigated. We found out optimum reaction conditions as following： the ultrasonic frequency was 30 kHz, the molar ratio of methanol to rapeseed oil was 7：1, the quality ratio of catalyst to rapeseed oil was 2.0%, in this case, the yield was up to 94%1 Then the performance of the obtained bio-diesel was investigated, which reach the current bio-diesel standards in Germany.
