摘要
采用共沉淀法制备了La-Mg-Al类水滑石,利用XRD进行了表征,考察了该催化剂的制备条件,并探究了催化大豆油酯交换反应的优化条件。实验结果表明,在金属物质的量比为1∶2∶1,焙烧温度为500℃,焙烧时间为3h的条件下制得的催化剂活性较高,并在反应温度为65℃,反应时间为3h,醇油物质的量比为9∶1,催化剂用量为大豆油质量的3%的优化条件下催化酯交换反应,生物柴油的收率达到90.9%。
La-Mg-Al hydrotalcite is prepared by co-precipitation method,and characterized by XRD.The preparation conditions of the catalyst are investigated.And the optimum conditions for catalyzing the exchange reaction of soybean oil ester are investigated.The experimental results show that the activity of the catalyst is high,under the conditions that the molar ratio of metal material is 1∶2∶1,calcination temperature is 500℃,calcination time is 3 h.The yield ratio of biodiesel reaches 90.9%with the reaction temperature of 65℃,the reaction time of 3 h,a mass ratio of 9∶1,a catalyst amount of 3%soybean oil quality and other optimized conditions under the transesterification reaction.
