Abstract

The invention discloses a pour point depressant composition suitable for biodiesel and petroleum diesel blend oil, a preparation method and application of the pour point depressant composition. The pour point depressant composition is formed by mixing phthalic acid ester type organic solvent, acetate type organic solvent and diesel oil pour point depressant. Specifically, the pour point depressant composition is prepared from 0-15 wt% of dimethyl phthalate, 10-30 wt% of diethyl phthalate, 0-10 wt% of dibutyl phthalate, 0-25 wt% of butyl acetate and 20-60 wt% of pour point depressant. By evenly mixing and stirring all the components at normal temperature and normal pressure and conducting ultrasonic dispersion for 25-30 minutes, the pour point depressant composition is prepared. The pour point depressant composition is particularly suitable for improving low-temperature mobility of biodiesel and petroleum diesel blend oil formed by mixing soybean oil biodiesel and 0# biodiesel at normal temperature and normal pressure, the pour point effect is remarkable, the cold filter plugging point can be reduced by 7-11 DEG C, and the pour point can be reduced by 6-10 DEG C.

Description

technical field [0001] The invention relates to a pour point depressant composition suitable for biodiesel-petrochemical diesel blended oil, a preparation method and application thereof, and belongs to the technical field of research and development of biomass energy additives. Background technique [0002] With the rapid development of our country's economy, the massive burning of fossil fuels has caused serious impacts on the environment and people's lives. Limited fossil energy and increasingly serious environmental problems make people urgently need a sustainable green energy. Biodiesel is a mixed fatty acid ester produced by the esterification reaction of free fatty acids or animal and vegetable oils with methanol, ethanol and other alcohols under the action of a catalyst. Biodiesel has many advantages. First of all, it has a wide range of raw materials and low price, and it is a renewable energy source; secondly, biodiesel is non-toxic, low in sulfur content, green an...
