Problems solved by technology

Although fatty acid anti-wear agents can significantly improve the anti-wear performance, it is easy to cause metal corrosion
Fatty acid esters are mainly prepared from long-chain unsaturated fatty acids and polyols. The cost of raw materials for polyols is high, and the product may contain unreacted fatty acids
The problem with the derivatives of fatty acid amides or fatty acid salts is the selectivity of oil products. In some experiments, the anti-wear properties of diesel oil can be improved, but in some experiments, the anti-wear properties of diesel oil can be reduced.

Abstract

The invention relates to a low-sulfur diesel lubrication anti-wear agent. The lubrication anti-wear agent is prepared by blending at least one kind of ester-type oily components, at least one kind of amide-type oily components and at least one kind of low-sulfur solvent components evenly and mechanically. The lubrication anti-wear agent has the effects of increasing lubrication, improving oxidation stability, carrying out effective cleaning and the like from the perspective of improving wear resistance of low-sulfur diesel. The lubrication anti-wear agent is free of poison and heavy metal, small in adding amount and convenient to use, quality of diesel products generated by oil refineries can be improved, the addition technology is simple, product quality is improved, and meanwhile production cost is reduced. The lubrication anti-wear agent can be applied to the low-sulfur diesel and can obviously improve the lubricating property of diesel.

Description

Technical field [0001] The invention belongs to the technical field of preparation of chemical products, and relates to a diesel fuel additive, in particular to a low-sulfur diesel lubricating and antiwear agent that can be used to produce high-power clean diesel. Background technique [0002] As the country and all sectors of society pay more and more attention to environmental protection issues, the production of high-quality oil products has become the development direction of the modern oil refining industry. In terms of automotive diesel production, the improvement of oil product standards is mainly manifested in the reduction of sulfur content, and the level of sulfur content is an important indicator that determines the cleanliness of automobile exhaust. Sulfur is the most harmful element that increases CH and C0 in diesel engine emissions, especially inhalable particulate matter. Therefore, reducing the sulfur content in diesel is particularly important for improving air ...
