Problems solved by technology

The use of low-sulfur diesel fuel in diesel fuel can greatly reduce the emission of particulate matter (PM) caused by sulfur elements and aromatic hydrocarbons, and greatly prolong the service life of exhaust gas catalysts. The aggressive substances will be removed along with the sulfur reduction process, which will have varying degrees of influence on diesel lubricating performance, combustion performance, low temperature flow performance and detergency performance

Abstract

The invention provides a low-sulfur diesel additive composition, comprising dispersant: diesel lubricity improver: pour point depressant: cetane number improver: low-sulfur solvent in the ratio by weight of 1: 0.5-10: 0.5-50: 0.5-100: 0.5-200 composition. As an additive for low-sulfur diesel oil, the low-sulfur diesel additive composition of the present invention does not introduce new sulfur elements and can meet environmental protection regulations. It can not only avoid the harm caused to vehicles by introducing new sulfur elements in ordinary low-sulfur diesel oil additives, but also Significantly improve the lubricating performance of diesel, reduce the wear of the fuel injection system, increase the service life of the engine, increase the cetane number of diesel, enhance its combustion performance, and reduce pollution such as coke, particulate matter, incomplete combustion emissions, and CO Reduce the emission of pollutants, reduce carbon deposits in the engine, prolong the life of the engine, improve the thermal efficiency of the engine, and reduce fuel consumption.

Description

technical field [0001] The invention relates to the technical field of energy combustion, in particular to a low-sulfur diesel oil additive composition and a preparation method thereof. Background technique [0002] As a product of petroleum refining, diesel oil occupies a relatively high share in the fuel structure of various countries. In addition, diesel engines for automobiles are more fuel-efficient than gasoline engines (about 30v%), and the CO and HC emissions of diesel engines are lower than those of gasoline engines with the same performance. 2 It is also less than gasoline engines, which is conducive to energy saving and environmental protection. Therefore, the trend of diesel vehicles at home and abroad is accelerating, and the demand for diesel will increase in the future. [0003] Sulfur content is an important indicator of the properties of vehicle diesel, which is used to characterize the corrosion performance of vehicle diesel and its influence on exhaust co...
