Problems solved by technology

[0004] The present invention aims at the singleness problem of diesel oil composite additives in the existing petrochemical industry, and provides a diesel multifunctional composite additive capable of reducing fuel consumption and tail gas emission pollution. Alkane number improver, pour point depressant, antioxidant, metal corrosion inhibitor and co-solvent are prepared by uniform mixing. This diesel compound additive can improve diesel detergency, low temperature fluidity, oxidation resistance and corrosion resistance. At the same time improve fuel combustion performance, reduce fuel consumption, and reduce vehicle exhaust pollutants

Abstract

The invention relates to the technical field of chemical industry and relates to a multifunctional diesel composite additive capable of reducing the oil consumption and reducing the pollution of the exhaust emission. The diesel composite additive is mainly formed by uniformly mixing a clearing agent, a smoke abatement combustion improver, a cetane number improver, a pour point reducer, an antioxidant, a metal corrosion inhibitor and a cosolvent. The diesel composite additive can improve the clearness, the low-temperature mobility, oxidation resistance and corrosion resistance of the diesel, also can improve the combustion performance of the fuel, can reduce the oil consumption and can reduce the pollution of the exhaust emission.

Description

technical field [0001] The invention relates to the technical field of petrochemical industry, and relates to a multifunctional composite additive for diesel oil capable of reducing fuel consumption and tail gas emission pollution. Background technique [0002] Under the background of depletion of oil resources, declining global oil reserves, and with the widespread use of diesel engines, my country's demand for diesel is increasing day by day. At the same time, the utilization rate of my country's petroleum products, especially motor vehicle fuel, is generally low. Not only caused the waste of fuel oil, but also caused the problem of aggravated air pollution due to the generation of motor vehicle exhaust pollutants. Therefore, further reducing the fuel consumption and pollutant emissions of diesel vehicles is an urgent problem to be solved at present. Among the many solutions, the method of using diesel additives is to change the physical and chemical properties of the fuel...
