Problems solved by technology

[0004] At present, mainstream lubricity improvers have been widely used in major oil refineries all over the world. The main defect is that these lubricity improvers have a high freezing point. Before use, they need to be heated on site to make them liquefied, which is very uncomfortable to use. Convenience, especially in southern refineries, many do not have the conditions for heating additives, and there is an urgent need to use low freezing point diesel lubricity additives
At present, there are many literatures and patent reports to reduce the lubricity of diesel oil through the process, but because of the huge processing cost, there are few applications at present.

Abstract

The invention discloses a low pour point diesel fuel lubricity improver composition prepared by compounding a pour point reducer with fatty acid, fatty acid ester and oleic acid amide and the like, and the solidifying point of the combination can be obviously reduced.

Description

technical field [0001] The invention belongs to the additive technology for improving the lubricity of low-sulfur diesel oil in the refining industry, in particular to a low-pour point diesel lubricity improver composition Background technique [0002] In order to further improve the atmospheric environment on which human beings depend and improve the quality of diesel engine exhaust emissions, domestic and foreign fuel oil production companies have begun to adopt deep processing and refining processes in recent years to produce low-sulfur diesel oil characterized by low sulfur content and low aromatic hydrocarbon content. Diesel engines burning low-sulfur diesel greatly reduce particulate matter (PM) emissions caused by sulfur elements and aromatic hydrocarbons, and greatly prolong the service life of exhaust gas catalysts. The ring form exists in aromatic hydrocarbons and polycyclic aromatic hydrocarbons, and the non-selective desulfurization process removes aromatic hydro...
