Abstract

The invention discloses ternary compound low-alcohol-type biodiesel with the low-temperature fluidity and a preparation method thereof. The ternary compound low-alcohol-type biodiesel is prepared by mixing, by volume, 5-30 parts of drainage oil biodiesel, 5-30 parts of lower-carbon alcohol and 60-90 parts of direct coal liquefaction diesel. The ternary compound low-alcohol-type biodiesel with the low-temperature fluidity is prepared through the steps that ultrasonic dispersion is conducted on the drainage oil biodiesel, the lower-carbon alcohol and the direct coal liquefaction diesel for 15 min to 20 min at room temperature, and standing is conducted for 4 h to 5 h. The ternary compound low-alcohol-type biodiesel has the excellent low-temperature fluidity, is simple and efficient in preparation process, green and environmentally friendly, and can be directly applied to a diesel engine without other treatment; compared with pure drainage oil biodiesel, the turbidity point, the cold filter plugging point and the pour point of the ternary compound low-alcohol-type biodiesel are lowered by 19 DEG C to 40 DEG C, 21 DEG C to 41 DEG C and 24 DEG C to 53 DEG C respectively, and the normal working requirements of various diesel motor vehicles at low temperature can be met.

Description

technical field [0001] The invention belongs to the technical field of chemical industry and relates to biodiesel, in particular to a ternary composite low-alcohol biodiesel with low-temperature fluidity and a preparation method thereof. Background technique [0002] Biodiesel is a good substitute for green and environment-friendly petrochemical diesel, which has excellent safety and lubricity, environmental friendliness and easy degradation. It is mainly a long-chain fatty acid mixed ester prepared by reacting various animal and vegetable oils, frying oil, gutter oil, etc. with methanol. The main indicators of biodiesel are basically the same as those of petrochemical diesel, and it has excellent compatibility with diesel. It can be mixed with diesel in any proportion, and can be added directly without modifying the diesel engine. In addition, biodiesel also has the advantages of wide source of raw materials, renewable, wide applicability, and high benefit. It is a renewab...
