  • Method for rapidly preparing biodiesel under low temperatures
    Patent number: 12163102
    Abstract: Disclosed is a method for rapidly preparing biodiesel at low temperatures, belonging to the technical field of chemical energy. The method includes the following steps: adding alkali catalyst, alcohol and organic solvent into grease, and obtaining the biodiesel through transesterification. The transesterification is carried out with the addition of organic solvent, including petroleum ether or n-hexane to improve the compatibility between the two phases of alcohol and grease, increase contact area between the two phases of alcohol and grease, reduce mass transfer resistance between the two phases of alcohol and grease, and promote the grease molecules to enter the methanol solution and dissolving of oil in the grease.
