Problems solved by technology

Among the existing additives, the sulfur-containing anti-wear agent is not suitable for low-sulfur diesel oil because it contains sulfur element itself, and the phosphorus-containing anti-wear agent is easy to affect the exhaust gas treatment device, with large side effects; the fatty acid anti-wear agent used in jet fuel is due to Poor compatibility with lubricating oil, and cannot be used in low-sulfur diesel

Abstract

The invention discloses a low sulfur diesel antiwear additive. The low sulfur diesel antiwear additive is prepared from the components in parts by weight: 3-8 parts of triethanolamine, 10-30 parts of toluene, 30-80 parts of castor oil acid, 10-30 parts of glycerol, 5-20 parts of polyethylene glycol and 2-6 parts of antioxidant. According to the low sulfur diesel antiwear additive disclosed by the invention, the glycerol and the polyethylene glycol with a proper proportion are used as polyhydric alcohols, and reaction is carried out on the polyhydric alcohols and the castor oil acid to prepare the low sulfur diesel antiwear additive. The low sulfur diesel antiwear additive has the advantage of low acid value and can be used for obviously improving the lubricating property of diesel.

Description

[0001] technical field [0002] The invention belongs to the technical field of diesel oil additives, in particular to a low-sulfur diesel antiwear agent. Background technique [0003] As countries around the world pay more and more attention to environmental protection issues, the production of high-quality clean diesel has become the development direction of the modern oil refining industry. This diesel is low in sulfur, low in aromatics, high in cetane and light in distillates. Sulfur is the most harmful element that increases CH and CO in diesel engine emissions, especially inhalable particulate matter, so reducing the sulfur content in diesel is particularly important to improve air pollution. However, due to the harsh hydrodesulfurization process commonly used in the production of low-sulfur diesel oil, the content of oxygen-containing and nitrogen-containing compounds, polycyclic and bicyclic aromatic hydrocarbons in diesel oil is also reduced, which reduces the na...
