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.
