The method has certain innovation, but the anti-riot effect as gasoline anti-knock agent is not significant, the economy is not good, and it cannot be used on a large scale
Patent CN102229823A reports a gasoline antiknock agent, which is not economical, and the sources of raw materials are not extensive, and the raw materials are very specific and unstable
Patents CN101298573A, CN102585933A, CN101768485A, CN102746919A, and CN102899103A all added MMT, among which toxic organic substances such as toluene were added, and even iron and other metals within the national standard limit range were added, which would pollute the air and water bodies and increase PM2.5 value

Abstract
The invention discloses a formula of a dust-free composite gasoline additive and a preparing method. The additive belongs to petroleum product additives and is used for improving the anti-knock performance of gasoline. Due to the requirement of environment protection, the nation and the whole society have increasingly-high urgent demands for improving the quality of the gasoline, so that many refinery plants, filling stations and petrochemical product factories adopt different ways to meet the requirements of a new gasoline standard. As the requirements for the content of metal, the content of olefin and the like are stricter, an ideal effect can not be obtained only through an original processing and mixing method, and a novel effective anti-knock agent responsible for the society needs to be developed to be used for replacing unreasonable products. Under the condition, the novel product which is simple in production technology, low in cost, free of dust and metal, low in emission and toxicity and capable of remarkably improving the anti-knock performance of the gasoline after mixing is provided. The economic value of fuel can be effectively increased, and the additive can be widely applied to mixing in various stages of gasoline products.
Description
Technical field [0001] The outer doped in the invention involved in oil products is specifically a preparation method for ash -free compound gasoline additives. Background technique [0002] The deleane value (90#, 93#, 97#) can also be called gasoline label, or anti -violent value. It is the most important quality index for vehicle gasoline. It comprehensively reflects the level of oil refining industry and vehicle design level.The use of anti -explosion agents is an important means to improve the alkane value of vehicle gasoline.Anticochrums can also be called octane promoters, and anctane renewal.It is generally used for gasoline for different device components of refining and chemical companies. It has the performance of enhancing automotive power and reducing harmful gas emissions, and at the same time makes oils have better economic value.With the further industrialization process of the country, the number of cars is increasing rapidly, and gasoline and other basic suppli...
