Abstract

The invention relates to a benzene ring-containing biodiesel pour point depressant composition as well as preparation and an application of the biodiesel pour point depressant composition. The pour point depressant composition is prepared from the following components in percentage by weight: 20 to 60 percent of polytetradecyl methacrylate-styrene methacrylate, 10 to 20 percent of span 80, 10 to 20 percent of ethanolamine and 20 to 40 percent of fatty alcohol-polyoxyethylene ether. Compared with the prior art, the biodiesel pour point depressant composition has the advantages that growth and aggregation of crystals can be effectively inhibited by changing the crystallization behavior of biodiesel, and the low-temperature performance of the biodiesel is effectively improved.

Description

technical field [0001] The invention relates to the technical field of biodiesel pour point depressants, in particular to a benzene ring-containing biodiesel pour point depressant composition and its preparation and application. Background technique [0002] In the process of biodiesel replacing traditional petrochemical diesel, there are huge challenges in the low temperature fluidity of biodiesel. Biodiesel is prone to crystallization at low temperatures, which reduces its applicability. Low-temperature fluidity improver is a kind of oil additive that can improve the crystallization process of wax in oil and lower the freezing point by adding a small amount. It is the lowest production cost, the most flexible and the most promising method for improving the low-temperature fluidity of biodiesel. One of the widest means. [0003] At present, the commonly used diesel pour point depressants at home and abroad mainly include methacrylate, ethylene vinyl acetate, maleic anhydr...
