Abstract

The invention relates to a polar nitrogen-containing diesel oil pour point depressant composition as well as preparation and application thereof. The diesel oil pour point depressant composition is prepared from the following components in percentage by weight: 10-40% of triethanolamine; 10 to 40 percent of span 80; 0 to 20 percent of fatty alcohol-polyoxyethylene ether; and 40 to 60% of N,N-phenyl methacrylamide-tetradecyl methacrylate. Compared with the prior art, the dispersity of the pour point depressant in 0 # diesel oil sold in the market can be improved, the condensation point of the pour point depressant can be reduced by 22-26 DEG C, and the cold filter plugging point of the pour point depressant can be reduced by 8-12 DEG C.

Description

technical field [0001] The invention belongs to the technical field of diesel pour point depressants, and relates to a polar nitrogen-containing diesel pour point depressant composition and its preparation and application. Background technique [0002] Diesel cold filter performance improver is an important fuel additive in diesel production. It can significantly change the low-temperature flow properties of diesel oil, thereby widening the distillation range of diesel oil, increasing the yield of diesel oil, and improving the quality of diesel oil, which is of great significance for increasing the economic benefits of refineries. Domestic research on diesel pour point depressants began in the 1960s, but there were some problems in the early development work: first, the index to measure diesel performance used to be only the freezing point, and second, domestically developed varieties were still mainly imitation. There is a problem of strong dependence on diesel and poor se...
