Description
Technical Field
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 antistatic complexing agent capable of simultaneously improving the lubricating property and the antistatic capability of diesel.
Background
In the aspect of diesel oil production, the improvement of oil standards is mainly reflected in the reduction of sulfur content. In order to meet the requirement of low sulfur content of diesel oil and improve the exhaust quality of diesel engines, deep processing refining technologies such as hydrodesulfurization and the like are generally adopted by petroleum refineries at home and abroad at present, so that the diesel oil develops towards low sulfur content. However, when sulfur and aromatic hydrocarbons in the diesel fuel component are removed in a large amount, the lubricating component with the anti-wear function is also removed, so that the lubricity of the diesel fuel is reduced, which in turn causes excessive wear of a fuel injection pump and a cylinder of a diesel engine. On the other hand, during the storage, transportation, infusion and processing of the oil products, the static electricity is inevitable because the relative movement of friction and separation such as stirring, sedimentation, impact, splashing and the like always occurs. According to the requirements of GB6950-2001 'light oil safety static conductivity' issued and implemented by China, the conductivity of light oil products of kerosene, diesel oil and gasoline is greater than 50 pS.m-1. The electrical conductivity of oil products is very low, especially light oil products (such as diesel oil with the resistivity of 7.3 x 1014 omega cm), and static electricity is easy to generate and accumulate. In the processes of oil production, storage, loading and unloading, transportation and use, the friction between oil products and the wall of a storage container or an oil pipeline is easy to generate very dangerous static electricity, and the static electricity can generate static sparks after being accumulated to a certain degree, so that explosive mixed gas is ignited to cause serious disasters such as explosion, fire and the like. The six standards of diesel oil begin to be enforced since 2018, although the sulfur content of the diesel oil is well controlled (less than 10ppm), the sulfur, phosphorus, nitrogen and other polar substances containing heteroatoms are removed, so that the current diesel oil products sold in the market are poor in lubricity and poor in conductivity.
