A kind of preparation method of bio-based diesel fuel lubricating antiwear agent

Abstract

The invention discloses a preparation method of a bio-based diesel fuel lubricating antiwear agent, and belongs to the technical field of preparation of antiwear agents. The preparation method comprises the following steps of using biomass castor oil as a raw material, saponifying and acidifying, so as to obtain castor oil fatty acid; reacting with diethanol amine, so as to obtain a lubricating base material with an oleic alkanolamide structure; using an oil and water interface method to obtain nano cerium oxide; doping, and dispersing into the base material, so as to obtain the lubricating antiwear agent. The preparation method has the advantages that by utilizing higher catalytic oxidization activity of cerium oxide, the combustion temperature of diesel soot is decreased, so that the exhaust emission of carbon particulate matters is obviously reduced; by mixing with the lubricating base material with the oleic alkanolamide structure, the problem of unobvious effect of reducing exhaust emission by the traditional diesel additive is solved, the defects of poor improvement of lubricating condition of diesel and unobvious effect of wear resistance are overcome, and the use effect is better.

Description

technical field [0001] The invention discloses a preparation method of a bio-based diesel fuel lubricating antiwear agent, which belongs to the technical field of chemical product preparation. Background technique [0002] The global shortage of oil resources has prompted more and more attention to the research of new energy, especially some developed countries have invested huge funds to develop new resources to replace natural energy. Therefore, saving energy is of great significance to the survival and sustainable development of human beings. More and more countries regard the development of new energy and energy conservation as an important task of development and research. At present, domestic petroleum refineries generally adopt deep processing and refining processes such as hydrogenation to make diesel oil develop in the direction of low sulfuration. However, during the hydrogenation process of diesel oil, with the removal of a large amount of sulfur and aromatics in...

Problems solved by technology

[0004] The technical problem mainly solved by the present invention: the diesel oil additives currently on the market have no obvious effects in improving engine power and reducing exhaust gas emissions, the actual fuel saving rate is low, and the lubrication of diesel oil is not well improved. In terms of wear resistance The defect of no significant effect provides a preparation method of bio-based diesel fuel lubricating and anti-wear agent; the present invention uses biomass castor oil as raw material to obtain castor oil fatty acid through saponification and acidification treatment, and then reacts with diethanolamine to prepare Lubricating base material with oleic acid alcohol amide structure, and then prepare nano-cerium oxide by oil-water interface method, dope and disperse in the base material to obtain lubricating and anti-wear agent; the invention utilizes the high catalytic oxidation activity of cerium oxide to reduce diesel oil Soot combustion temperature, thereby significantly reducing carbon particulate exhaust emissions, and blending with lubricating base materials with oleic acid amide structure, not only solves the problem that traditional diesel additives have no obvious effect in reducing exhaust emissions, but also makes up for the lack of good improvement The lubricating condition of diesel oil has no significant effect on anti-wear defects, and has an excellent use effect
