Abstract

The invention discloses bus biodiesel and a preparation method. The bus biodiesel is formed by adding pour point depressant to mixed diesel formed by mixing gutter oil biodiesel with mineral 0# diesel and then evening mixing the mixture; in percentage by volume, the amount of the pour point depressant comprises to the amount of mixed diesel is 5%-25%: 75%-95%; in percentage by volume, the content of gutter oil biodiesel in the mixed diesel is 10%-50% and the content of the mineral 0# diesel is 50%-90%. According to the preparation method, gutter oil is used as a raw material, graphene oxide is used as a catalyst to catalyze the gutter oil to have transesterification with methanol, the obtained gutter oil biodiesel is mixed with the 0# diesel, the pour point depressant is added, and the bus biodiesel is obtained. Compared with 0# automotive diesel, the cold filter plugging point, the pour point, the cloud point, the closed-cup flash point, the kinematic viscosity, the oxidation stability, the calorific value, the density, the acid value and the like of the bus biodiesel conform to related automotive diesel standards.

Description

technical field [0001] The invention relates to a biodiesel for buses and a preparation method thereof, belonging to the field of biomass energy utilization. Background technique [0002] Biodiesel is a renewable clean energy that is extracted from vegetable oils and can be used in tractors, trucks, ships, etc. It refers to oil crops such as soybeans, rapeseed, cotton, palm, etc., wild oil plants and engineering microalgae and other aquatic vegetable oils, animal oils, and catering waste oils, etc. Regenerative diesel fuel. [0003] Biodiesel is a kind of biomass energy. It is a mixture of complex organic components with extremely high oxygen content. Phenols, organic acids, alcohols, etc. Compared with traditional petrochemical diesel, biodiesel contains no aromatics, no sulfur, high flash point, high cetane number, good lubricity and biodegradability, renewable plant sources, non-toxic and beneficial The carbon cycle is an important substitute for ideal petrochemical d...
