一种固体碱催化剂的制备方法
摘要：
本发明涉及生物柴油制备技术领域，尤其涉及一种固体碱催化剂的制备方法，包括：步骤a：将ZnO、Ca(OH)2和KF·2H2O混合为混合物，其摩尔比为2.0∶1.0∶（0.5～2.0）；步骤b：加入去离子水进行研磨，其与混合物的摩尔比为(2.5～3.5)∶16；步骤c：在70℃～90℃的温度下干燥5～7小时；步骤d：在250℃～500℃的温度下烘培5～7小时，得到ZnO/Ca(OH)2/KF固体碱。本发明采用上述方法，制备简便，制备出的固体碱催化效果好。
摘要（英）：

The invention relates to the technical field of biodiesel preparation and in particular relates to a preparation method of a solid base catalyst. The preparation method comprises the following steps: a. mixing ZnO, Ca(OH)2 and KF.2H2O in a mole ratio of 2.0 to 1.0 to (0.5-2.0) to form a mixture; b. adding deionized water to grind the mixture, wherein the mole ratio of the deionized water to the mixture is (2.5-3.5) to 16; c. drying the paste at a temperature of 70-90 DEG C for 5-7 hours; d. baking the paste at a temperature of 250-500 DEG C for 5-7 hours, thus obtaining ZnO/Ca(OH)2/KF solid base. The method is simple and convenient in preparation, and the prepared solid base has good catalytic effects.
