Abstract

The invention discloses a non-metal antiknock agent for gasoline. The non-metal antiknock agent comprises the following active ingredients in parts by weight: 15-40 parts of an ester octane number modifier, 10-20 parts of an amine octane number modifier, 15-30 parts of an ether octane number modifier, 10-20 parts of an amide octane number modifier, 15-30 parts of an organic phenol octane number modifier, 3-8 parts of an alcohol octane number modifier, 3-8 parts of a cleaning dispersant, and 3-8 parts of a cosolvent. A preparation method of the non-metal antiknock agent for the gasoline comprises the following steps: (1) weighing the active ingredients in the corresponding parts by weight according to the foregoing requirements; (2) sequentially putting the ingredients into a reaction kettle with a stirring device, and performing full and uniform mixing under stirring; and (3) allowing the mixed solution to stand for one hour or more so as to obtain the non-metal antiknock agent. The non-metal antiknock agent disclosed by the invention effectively promotes improvement of an octane number of the gasoline, improves oxidation resistance of the gasoline, ensures indexes and quality of the gasoline, and reduces damage to the environment caused by exhaust gas emission; and the non-metal antiknock agent has predictable high economic value and social value.

Description

Technical field: [0001] The invention relates to the technical field of petroleum product vehicle fuel additives, and in particular provides a non-metallic gasoline antiknock agent and a preparation method thereof. Background technique: [0002] With the continuous development of society and the continuous progress of science and technology, due to the continuous improvement of people's awareness of environmental protection of vehicle fuels, relevant scientific and technological personnel are also constantly developing vehicle fuel additives to increase the octane number of vehicle gasoline and improve its antiknock Resistance, that is, anti-knocking of gasoline engines. [0003] So, what is the knocking of gasoline engine? When the gasoline engine is working, the air and fuel oil are fully mixed. After the intake stroke enters the combustion chamber, the piston compresses it during the compression stroke, and the spark plug ignites the high-pressure mixture. Power; due to...
