Problems solved by technology

These additives can improve the low-temperature fluidity of diesel to a certain extent, promote the combustion of diesel or improve the anti-explosion performance of diesel, but they have a single function, which can only improve a certain performance of diesel, and do not improve other performances of diesel. Some additives are improving When one performance of diesel is reduced, other properties and indicators of diesel will be reduced. For example, low-temperature flow improvers containing aromatic hydrocarbons will increase the content of benzene and toluene in diesel, and at the same time reduce the antiknock performance of diesel; The fuel catalyst of methyl chloride has a strong corrosion effect on iron containers, and increases the chloride content in the tail gas, and the fuel catalyst containing ethanol and benzene with a low cetane number will reduce the antiknock performance of gasoline; and, the existing Due to the lack of synergistic effect among diesel additives, they cannot be used in combination to make up for their respective deficiencies to achieve the purpose of improving the overall performance of diesel
Moreover, most of the existing diesel oil additives contain aromatic hydrocarbons, which increases the content of benzene in diesel oil.

Abstract

The invention belongs to the field of chemical industry, relating to a diesel additive component, in particular to a novel diesel additive component capable of improving various diesel properties. The invention discloses the novel diesel additive component comprising cetane number improver, clean dispersant, combustion improver, antioxidant and metal passivator and low-temperature flow improver. The diesel additive provided by the invention has a strong cleaning function, removed carbon deposit particles are easy to disperse in diesel without causing the phenomena of fuel path blockage and the like. The novel diesel additive component provided by the invention also contains antioxygen and anticorrosion components, thus various parts of the fuel path system can be inhibited from rusting and corroding, and the service life is prolonged.

Description

technical field [0001] The invention belongs to the field of chemical industry and relates to a diesel additive component, in particular to a novel diesel additive composition capable of improving multiple diesel properties. Background technique [0002] At present, there are three main types of diesel additives on the market: low temperature fluidity improvers, fuel catalysts and cetane number improvers. These additives can improve the low-temperature fluidity of diesel to a certain extent, promote the combustion of diesel or improve the anti-explosion performance of diesel, but they have a single function, which can only improve a certain performance of diesel, and do not improve other performances of diesel. Some additives are improving When one performance of diesel is reduced, other properties and indicators of diesel will be reduced. For example, low-temperature flow improvers containing aromatic hydrocarbons will increase the content of benzene and toluene in diesel, ...
