摘要
以SBA-15为载体,通过浸渍法制备了MgO-CaO/SBA-15固体碱催化剂。优化的的催化剂制备条件是:镁钙物质的量比为0.4,焙烧时间为2 h,焙烧温度为700℃。在应温度为65℃,醇油物质的量比为12∶1,催化剂用量为大豆油质量的3%,可得生物柴油产率为85.5%。
The MgO-CaO/SBA-15 solid base catalysts were prepared byimpregnation me-thodwith SBA-15 as the carrier and used in the transesterification of soybean oil with methanol.The optimum preparation conditions of the catalyst were as follows:the mass ratio of magnesium to calcium was 0.4,the calcination time was 2 h,and the calcination temperature was 700℃.When the reaction temperature was 65℃,ratio of alcohol to oil was 12∶1,catalyst dosage is 3%of the soybean oil quality,and the biodiesel yield is 75.2%.
