NONCATALYTIC PROCESS FOR PRODUCING BIODIESEL FUEL THAT DOES NOT GENERATE BY-PRODUCT

摘要

THIS INVENTION PROVIDES A PROCESS FOR PRODUCING BIODIESEL FUEL FROM VEGETABLE OR ANIMAL OILS AND FATS OR WASTES THEREOF AND METHANOL THAT NOT USE A CATALYST AND DOES NOT GENERATE GLYCERIN AS A BY-PRODUCT. IN THIS PROCESS, VEGETABLE OR ANIMAL OILS AND FATS OR WASTES THEREOF ARE MIXED WITH METHANOL, AND A METHANOLYSIS REACTION IS CARRIED OUT AT A REACTION TEMPERATURE OF BETWEEN 370° AND 500°C, A REACTION PRESSURE OF BETWEEN 20 MPA AND 60 MPA, AND A REACTION PERIOD OF BETWEEN 4 MINUTES AND 12 MINUTES WITHOUT THE USE OF A CATALYST. THIS INVENTION ALSO PROVIDES BIODIESEL FUEL THAT IS MAINLY COMPOSED OF FATTY METHYL ESTERS, MONOACYLGLYCEROL, AND DIACYLGLYCEROL .
