Abstract

The invention discloses a broad-spectrum biodiesel oil pour point depressant and a preparation method thereof. The broad-spectrum biodiesel oil pour point depressant is prepared by mixing ethyl acetoacetate biodiesel oil pour point depressant composition with polymethyl methacrylate according to a mass ratio of the ethyl acetoacetate biodiesel oil pour point depressant composition to polymethyl methacrylate of (1-3) to 1. The preparation method comprises the following steps: stirring and mixing the ethyl acetoacetate biodiesel oil pour point depressant composition and polymethyl methacrylate to obtain the broad-spectrum biodiesel oil pour point depressant. The obtained broad-spectrum biodiesel oil pour point depressant is good in pour point depression effect and also can be applied to general diesel oil.

Description

technical field [0001] The invention relates to a broad-spectrum biodiesel pour point depressant and a preparation method thereof, more specifically relates to a method of mixing ethyl acetoacetate pour point depressant with an organic solvent and stirring with polymethyl methacrylate to obtain The invention discloses a method for a broad-spectrum biodiesel pour point depressant, which belongs to the field of research and development of biomass energy additives. Background technique [0002] Biodiesel is a renewable diesel fuel that can replace petrochemical diesel produced by transesterification. One is biomass energy, which is a mono-alkyl ester of long-chain fatty acids obtained from biomass using thermal cracking and other technologies. Compared with traditional petrochemical energy, biodiesel has low sulfur and aromatic content, high flash point, high cetane number, and good lubricity. It can be partially added to fossil diesel, and has good environmental protection ch...
