Abstract
The invention relates to a method for preparing a biodiesel by catalysis of modified calcium oxide, which comprises the following steps: adding natural grease and short-chain fatty alcohol into a container, adding halogenated hydrocarbon surface-modified calcium oxide acting as a catalyst into the container while stirring, heating the mixture in the container while stirring, cooling to room temperature, filtering the mixture in the container to obtain a filtrate, finally standing the filtrate until the alcohol phase and the oil phase are stratified, and separating out the subnatant which is the biodiesel. The prepared biodiesel is a light yellow liquid product. By using methyl margarate as the interior label, the determination based on the gas phase chromatography shows that the conversion rate of the raw material grease is greater than 90%, and the yield can be increased by 5-15% as compared with the situation of using common calcium oxide as a catalyst under the identical conditions.
