Abstract

The invention discloses a diesel oil pour point depressant composition and its preparation method. The diesel oil pour point depressant composition, i.e. a diesel oil pour point depressant composition formed by mixing acetic ester organic solvents with a pour point depressant, comprises the following raw materials by mass percent: 0-20% of methyl acetate, 0-20% of ethyl acetate, 0-10% of propyl acetate, 0-30% of butyl acetate, and 20-80% of the pour point depressant. The preparation method consists of: mixing all the raw materials and then conducting stirring in water bath at a constant temperature of 50DEG C for 20min, and controlling the rotation speed at 150r / min, thus obtaining the diesel oil pour point depressant composition. Adding of the obtained diesel oil pour point depressant composition into commercially available 0# diesel oil can make the cold filter plugging point of the diesel oil reduced by 5-11DEG C and the condensation point reduced by 6-10DEG C. The diesel oil pour point depressant composition provided in the invention enhances the dispersion effect of pour point depressants on wax crystals, and improves the low temperature fluidity of diesel oil.

Description

technical field [0001] The invention relates to a pour point depressant composition and a preparation method thereof, in particular to a pour point depressant composition for diesel oil pour point depression and a preparation method thereof. Background technique [0002] Diesel pour point depressant, also known as diesel low-temperature flow performance improver, is an additive that can significantly reduce the freezing point and cold filter point of diesel and improve the low-temperature flow performance of diesel by adding a small amount. It mainly improves the low temperature flow properties of diesel through eutectic, adsorption, solubilization or nucleation. The research on diesel oil pour point depressant is of great significance to increase the output of diesel oil, save kerosene, increase the ratio of diesel to gasoline and improve the economic benefits of refineries. At present, in order to obtain a better cooling filter point reduction effect, domestic and foreig...
