Problems solved by technology

Since 2018, the National Six Standards for Diesel has been enforced. Although the sulfur content of diesel has been well controlled (less than 10ppm), at the same time, due to the removal of heteroatom-containing polar substances such as sulfur, phosphorus, and nitrogen, the current In addition to the low lubricity of commercially available diesel products, the electrical conductivity also becomes worse

Abstract

The invention relates to a diesel oil wear-resistant antistatic complexing agent capable of being used for improving the lubricating property and antistatic capacity of diesel oil, which is composed of a diesel anti-wear agent, an antistatic agent and a solubilizing and dispersing agent. The preparation method comprises the following steps: premixing the diesel oil anti-wear agent and the antistatic agent, adding the premixed diesel oil anti-wear agent and the antistatic agent into a mixing kettle together with the solubilizing and dispersing agent, heating to 35-50 DEG C, fully stirring, andfiltering by using a filter screen to obtain the product. The diesel oil anti-wear and anti-static complexing agent has the advantages of low sulfur content, no heavy metals, small addition amount, substantial improvement of the low temperature fluidity and the conductivity of diesel oil, and good compatibility with diesel oil. The quality of oil products can be improved, the blending workload isreduced, and the oil product transportation and storage safety is ensured.

Description

technical field [0001] The invention belongs to the technical field of preparation of chemical products, and relates to a diesel additive, in particular to a diesel anti-wear and anti-static composite agent which can be used to simultaneously improve the lubricating performance and anti-static ability of diesel. Background technique [0002] In terms of diesel production, the improvement of oil standards is mainly reflected in the reduction of sulfur content. In order to meet the low-sulfur requirements of diesel and improve the exhaust quality of diesel engines, oil refineries at home and abroad generally adopt deep processing and refining technologies such as hydrodesulfurization to make diesel oil develop in the direction of low sulfur. However, when the sulfur and aromatics in the diesel components are largely removed, the lubricating components that play an anti-wear role will also be removed, which will reduce the lubricity of the diesel, which in turn will lead to exc...
