摘要

The method for producing biodiesel fuel, comprises mixing a mixture of vegetable oil and ether with superacidic granulates to cause an acidic ether cleavage, producing the ether in a reaction of an alcohol with superacidic granulates, separating excess ether from the ester and a produced glycerin by evaporation, physically removing the produced ester from the surface of the mixture, removing further excess ether from the ester by the application of negative pressure, and removing glycerin contained in the ester by hydrophilic granulates.
