Abstract

The invention discloses a non-metallic antiknock agent and a preparation method thereof. The non-metal antiknock agent contains no any metal component and is prepared through the following steps of: sequentially adding 40-60 parts by weight of an amine octane value promoter, 20-40 parts by weight of an amide octane value promoter, 10-25 parts by weight of ester octane value promoter and 5-15 parts by weight of an alkylphenol octane value promoter, and then thoroughly stirring and evenly mixing all the promoters together. The non-metallic antiknock agent is capable of improving the octane value of gasoline by 2.0-7.0 units, and also capable of prolonging the induction period of the gasoline and reducing the content of extension gum, thereby guaranteeing the quality of the gasoline product; if the non-metallic antiknock agent is added to the gasoline, and as no metal deposition is formed, no harmful effect is generated on a spark plug and a generator; and therefore, the service life of the generator can be prolonged, and pollution to the environment and harm to the human body can be reduced.

Description

technical field [0001] The invention relates to the field of gasoline additives, in particular to a non-metallic antiknock agent capable of optimizing the antiknock performance of gasoline fuel so as to improve the octane number of gasoline products and a preparation method thereof. Background technique [0002] The octane number is the most important quality index of motor gasoline. It comprehensively reflects the level of a country's oil refining industry and vehicle design. Adding antiknock agents to gasoline is an important means to increase the octane number of motor gasoline. Gasoline antiknock agent can improve the antiknock performance of gasoline, that is, the octane number and antiknock index of the research method of the national standard "GB17930-20061" of unleaded gasoline for vehicles, and is the main means of producing high-grade gasoline. [0003] Gasoline engine knocking is related to the nature of the fuel. If gasoline is easy to oxidize, the peroxide forme...
