一种固体碱催化剂、其制备方法以及利用其催化合成生物柴油的方法
摘要：
一种固体碱催化剂、其制备方法以及利用其催化合成生物柴油的方法，本发明涉及固体碱催化剂、制备方法以及制备生物柴油的方法。本发明是要解决现有的制备新型生物柴油的催化剂的后续处理步骤复杂、有污染、不能重复使用的技术问题，本发明的固体碱催化剂为表面有孔的球状磷酸钠。制备方法：将Na3PO4·12H2O干燥后再焙烧，即得。合成新型生物柴油的方法：将脂肪酸甲酯、乙二醇单甲醚和固体碱催化剂加入反应器中，通入常压的氮气保护，在搅拌条件下升温度至60℃～140℃反应，然后离心分离，再将上层的液体减压蒸馏后即得，生物柴油的产率为82％～90％。固体碱催化剂重复使用3次后生物柴油的产率仍可达到72％～77％。
摘要（英）：

The invention relates to a solid base catalyst, a preparing method thereof and a method for utilizing the solid base catalyst to catalyze and synthesize biodiesel. The solid base catalyst mainly solves the technical problems that an existing catalyst for preparing the novel biodiesel is complex in follow-up treatment step, causes pollution and can not be reused. The solid base catalyst is spherical sodium phosphate with holes formed in the surface. According to the preparing method, Na3PO4.12H2O is roasted after being dried to obtain the solid base catalyst. According to the method for synthesizing the novel biodiesel, fatty acid methyl ester, ethylene glycol monomethyl ether and the solid base catalyst are added into a reactor, normal-pressure nitrogen is introduced for protection, under the stirring condition, temperature is raised to 60-140 DEG C, the mixture reacts and then is separated centrifugally, liquid of the upper layer is distilled in a pressure reduction mode to obtain the biodiesel, and the production rate of the biodiesel is 82-90%. After the solid base catalyst is reused three times, the yield of the biodiesel can still reach 72-77%.
