Nonmetal gasoline antiknock agent and preparation method thereof

Abstract

The invention provides a nonmetal gasoline antiknock agent and a preparation method thereof. The nonmetal gasoline antiknock agent comprises the following raw materials in parts by weight: 30-80 parts of N-methyl formamide, 2-8 parts of methyl tertiary butyl ether, 2-15 parts of 1-nitropropane, 5-20 parts of glycerol tripalmitate, 3-18 parts of nonyl phenol polyoxyethylene ether and 2-8 parts of a cosolvent. The cosolvent is methyl ethyl ketone, 2-naphthyl amine and 1,5-dimethyl hexyl amine. According to the nonmetal gasoline antiknock agent disclosed by the invention, the raw materials are scientifically compounded, have better compatibility and synergistically play a role, so that the purpose of improving the antiknock property of gasoline is achieved, sufficient combustion of gasoline is promoted, combustion carbon deposit in a cylinder is effectively eliminated, the combustion efficiency of gasoline is improved, and the requirements of refinery enterprises for blending international gasoline by using naphtha are met; and objective economic benefits can be created for enterprises.

Description

technical field [0001] The invention relates to the field of petrochemical industry, in particular to a non-metallic gasoline antiknock agent and a preparation method thereof. Background technique [0002] The development of the automobile industry, the urgency of energy saving and environmental protection, promote the upgrading of gasoline products. In order to improve the gasoline octane number, improve the refining process technology, or transfer high-octane number components, but this method has large investment and limited resources. And change the distillation range of gasoline and other issues, and among the non-metallic antiknock agents produced at present, a large number of non-metallic MTBEs are first used to blend gasoline, but the addition amount is large, the cost is high, and the environment has a certain impact . There is also the use of aniline gasoline antiknock, but because the aniline gasoline antiknock is highly toxic and unstable, it will reduce the com...

[0002] The development of the automobile industry, the urgency of energy saving and environmental protection, promote the upgrading of gasoline products. In order to improve the gasoline octane number, improve the refining process technology, or transfer high-octane number components, but this method has large investment and limited resources. And change the distillation range of gasoline and other issues, and among the non-metallic antiknock agents produced at present, a large number of non-metallic MTBEs are first used to blend gasoline, but the addition amount is large, the cost is high, and the environment has a certain impact

There is also the use of aniline gasoline antiknock, but because the aniline gasoline antiknock is highly toxic and unstable, it will reduce the combustion speed of gasoline and cause problems such as excessive nitrogen oxides in the tail gas; The demand for alkane number urgently requires the market to provide antiknock agents that can meet the needs
