Abstract

The invention discloses a diesel oxidized stabilizer composite which is prepared from the following raw materials in percentage by weight: 20-40 percent of screening phenols antioxidizer, 30-60 percent of amine antioxidizer, 10-20 percent of phosphate-contained antioxidizer, 5-10 percent of sulpho-esters antioxidizer and 5-10 percent of carboxylic acid compound. The diesel oxidized stabilizer composite can effectively reduce total insoluble substances of diesel oxidized sediments to effectively improve the color grade of the diesel. An additive for the composite has low manufacture cost, goodintersolubility with the diesel, and simple adding method without using new equipment; the additive has synergistic effect with other additions of the diesel and low solidifying point, being beneficial to winter storage and addition; moreover, the additive has the cleaning action on engines.

Description

technical field [0001] The invention relates to a diesel oil additive composition, in particular to an additive composition for inhibiting the generation of oxidation deposits by active components in diesel oil and improving the oxidation stability of diesel oil. Background technique [0002] With the acceleration of dieselization of vehicles worldwide, the demand for diesel is increasing, and the quality requirements for diesel are also getting higher and higher. Due to the limited production of crude oil, the widely used diesel oil is generally a blend of straight-line diesel oil and catalytic cracking diesel oil. For a long time, the stability of FCC diesel has been a common concern. Compared with straight diesel fuel, diesel fuel contains a large number of unstable components, such as olefins, polycyclic aromatic hydrocarbons, and non-hydrocarbon compounds such as sulfur and nitrogen. These compounds are prone to condensation or oxidation reactions under the action of o...
