Problems solved by technology

Most of the biodiesel pour point depressants at home and abroad continue to use traditional diesel pour point depressants, and there is a lack of effective pour point depressants for biodiesel. The freezing point itself is high, and the effect of simply using traditional pour point depressants is not good

Abstract

The invention discloses a biodiesel pour point reducer composition containing a Tween surfactant and a preparation method thereof. The biodiesel pour point reducer composition containing the Tween surfactant is formed by mixing Tween series surfactants and a biodiesel pour point reducer, wherein the materials comprise the following components by weight percent: 5 to 10 percent of Tween 20, 0 to 5 percent of Tween 40, 5 to 10 percent of Tween 60, 40 to 60 percent of Tween 80 and 0 to 50 percent of biodiesel pour point reducer. The preparation method comprises the following steps of: mixing the raw materials and stirring the raw materials in a thermostatic water bath condition, and controlling the rotating speed to 300 revolutions per minute for 15 minutes so as to obtain the biodiesel pour point reducer composition containing the Tween surfactant. The biodiesel pour point reducer composition is added into biodiesel, so that the cold filter plugging point of the biodiesel is reduced by 7 to 12 DEG C, the condensation point of the biodiesel is reduced by 7 to 13 DEG C, and the low temperature fluidity of a biodiesel product is improved.

Description

technical field [0001] The present invention relates to a kind of pour point depressant composition and preparation method thereof, more specifically relate to a kind of biodiesel depressant containing Tween surfactant composition and preparation method thereof and in traditional biodiesel depressant Coagulation applications. Background technique [0002] With the acceleration of the trend of vehicle dieselization worldwide, the demand for diesel will increase, and the depletion of oil resources and people's awareness of environmental protection have promoted the pace of developing diesel alternative fuels around the world, especially in the 1990s In the 1990s, biodiesel, as a green and environmentally friendly fuel, attracted the attention of governments all over the world. Biodiesel is fatty acid methyl ester (Fatty Acid Ester), chemical formula is RCOOCH 3 (R:C 12-24 ), mainly made of vegetable oil or animal fat, is a new type of clean and renewable energy that can r...
