Problems solved by technology

Adding the obtained biodiesel pour point depressant composition to kitchen waste oil biodiesel can reduce the cold filter point by 5-9°C and the condensation point by 4-9°C. Only conventional pour point depressants and Esters are mixed and compounded, but the problem of poor oil solubility of existing products has not been fundamentally changed, and the final pour point depressing effect is not ideal

Abstract

The invention relates to an efficient biodiesel pour point depressant composition. The efficient biodiesel pour point depressant composition is prepared from the following components in percentage bymass: 10-20% of dimethyl phthalate, 10-30% of diethyl phthalate, 5-20% of oleic alcohol ethoxylate and 40-60% of hexadecyl methacrylate-benzyl methacrylate-N-vinyl pyrrolidone. According to the efficient biodiesel pour point depressant composition, the dimethyl phthalate and the diethyl phthalate are used as good solvents, the surfactant oleic alcohol ethoxylate 1602 is used as a solubilizer, thesolvent base of a pour point depressant in biodiesel can be enhanced, the solubility and dispersity of the pour point depressant in diesel are improved, a condensation point and a cold filter pluggingpoint of the biodiesel are effectively reduced, and use of the biodiesel is popularized.

Description

Technical field [0001] The invention relates to the field of research and development of petrochemical energy additives, in particular to a high-efficiency biodiesel pour point depressant composition and a preparation method and application thereof. Background technique [0002] Biodiesel is also called biodiesel. Biodiesel is a typical renewable fuel and does not cause pollution to the environment. Research on replacing fossil fuels with biodiesel is extremely important for the progress of human civilization and the development of society. Diesel is a renewable fatty acid monoester, which can be derived from animals or plants. It is considered an environmentally friendly biofuel, biodiesel. However, the freezing point and viscosity of biodiesel are higher than that of mineral diesel, and the low temperature fluidity is poor. Therefore, to realize the widespread use of biodiesel, its low temperature fluidity must be improved. [0003] In terms of improving the low-temperature flo...
