Abstract

The invention discloses a biodiesel pour point reducer composition as well as a preparation method thereof. The biodiesel pour point reducer composition is composed of span-series surface active agents and a diesel pour point reducer through mixing; and the raw materials are composed of 0-5% of span-20, 0-5% of span-40, 0-5% of span-60, 40-60% of span-80 and 30-50% of the pour point reducer by mass. The preparation method comprises the following steps of: mixing the raw materials, and stirring in aqueous thermostat at the rotation rate of 200 r/min for 10 min to obtain the biodiesel pour point reducer composition. After the obtained biodiesel pour point reducer composition is added into the biodiesel, a cold filter plugging point is reduced by 6-10 DEG C, and a condensation point is reduced by 7-11 DEG C. The biodiesel pour point reducer composition disclosed by the invention enhances exposure level of the biodiesel pour point reducer and a wax crystal, and improves the low-temperature fluidity of a biodiesel oil product.

Description

technical field [0001] The invention relates to a pour point depressant composition and a preparation method thereof, more specifically to a pour point depressant composition for biodiesel depreciation, a preparation method thereof and an application in biodiesel depreciation. Background technique [0002] Biodiesel refers to fatty acid methyl esters or ethyl alcohols produced from raw materials such as oil crops, wild oil crops, engineering microalgae and other aquatic vegetable oils, animal fats, and catering waste oils through transesterification reactions with alcohols such as methanol or ethanol. Ester fuel is a high-quality diesel alternative. As an alternative fuel to petrochemical diesel, biodiesel has attracted widespread attention from all over the world, and large-scale production has been formed in European and American countries. However, the freezing point of biodiesel is generally around 0°C. At low temperatures, the crystallization of fatty acid methyl este...
