摘要：以浸渍法制备KNO3/MCM-41催化剂,并在超声辅助作用下,以此催化大豆油与甲醇酯交换反应制备生物柴油。考察反应条件对酯交换反应影响,实验表明,在超声功率150 W、醇油质量比8:1、催化剂加入量为原料油质量3.5%、反应温度65℃、反应时间50 min条件下,生物柴油产率可达92%,且所得生物柴油性能基本达到国外生物柴油标准。
The KNO3/MCM-41 catalyst was prepared by impregnation method.the transesterification of soybean oil to biodiesel catalyzed by KNO3/MCM-41 with ultrasound is studied.The effects of reaction conditions on the transesterification reaction was investigated.The results show that the reaction conditions are as following： ultrasonic power 150 W,molar ratio between methanol and soybean oil 8：1,mass ratio of catalyst to soybean oil weight 3.5%,reaction temperature 65 ℃,reaction time 50 min.The yield of biodiesel reached 92% under the optimum reaction conditions.Then the performance of the obtained bio-diesel was investigated,which reach the current bio-diesel standards abroad.
