Abstract

The invention discloses a pour point depressant composition of biodiesel for a bus and a preparation method of the pour point depressant composition. The pour point depressant composition of the biodiesel for the bus is formed by mixing the following components in parts by weight: 2.5-10 parts of isodecyl methacrylate, 2.5-10 parts of ethyl acetoacetate, and 2.5-10 parts of isooctyl methacrylate. The preparation method comprises the following steps of ultrasonically dispersing isodecyl methacrylate, ethyl acetoacetate and isooctyl methacrylate after uniformly mixing and stirring at normal temperature and normal pressure so as to obtain the pour point depressant composition of the biodiesel for the bus. The pour point depressant composition of the biodiesel for the bus is used for depressing the pour point of the biodiesel for the bus formed by mixing illegal cooking oil biodiesel with 0# fossil diesel at normal temperature and normal pressure; the low-temperature flow property of the biodiesel for the bus can be effectively improved; the cold filter plugging point is reduced by 5-8 DEG C; the condensation point is reduced by 4-8 DEG C; and the pour point is reduced by 6-8 DEG C.

Description

technical field [0001] The invention relates to a biodiesel pour point depressant composition for buses and a preparation method thereof, belonging to the field of research and development of biomass energy additives. Background technique [0002] With the development of the world economy, the scope of application of diesel engines for vehicles has gradually increased. In particular, the bus industry in my country has developed rapidly. Diesel buses still occupy a dominant position, and the production and consumption of petrochemical diesel have shown a momentum of continuous and rapid growth. However, the output of petrochemical diesel is far from meeting the demand of the market, and countries all over the world have been actively exploring and developing new alternative fuels. [0003] Biodiesel is a mixed fatty acid ester prepared by transesterification of oil crops, animal and vegetable oils, and waste cooking oil with alcohols such as methanol or ethanol. It is a green...
