摘　　要：目的介孔固体超强酸催化剂SO42-/ZrO2/MCM-41催化制备生物柴油.方法酯交换反应.结果得出最优制备方案:醇/油摩尔比6:1,反应温度65℃,催化剂用量3%,反应时间8h,产率为95.37%.结论以菜籽油油脚为原料制备的生物柴油,其性能与0#柴油相近.Objective Biodiesel was obtained through mesoporous solid acid catalyst SO4^2-/ZrO2/MCM-41. Method Transesterification was applied. Result The optimum preparation schemes were obtained： molar ratio of methanol to oil was 6：1, reaction temperature 65℃ , amount of catalyst 3%, reaction time 8 h, and yield of biodiesel 95.37%. Conclusion The major properties of biodiesel which was prepared by rape oil foots resembles that of 0^# diesel oil.
