Abstract

The invention relates to alcohol ether-based clean gasoline for vehicles. The alcohol ether-based clean gasoline consists of the following raw materials in mass percentages: 40-60% of straight-run gasoline, 20-30% of alkylation gasoline, 8-20% of petroleum ether, 5-10% of mixed alcohols, 0.5-2.8% of C4-C5 ether compounds, and 0.1-0.5% of C2-C3 diamine compounds. The alcohol ether-based clean gasoline has the advantages that byproducts (straight-run gasoline, alkylation gasoline and petroleum ether) of an oil refinery are adopted as main raw materials, a proper amount of alcohol, ether and diamine antiknock agents are added, and additives containing metal elements are not contained, so that compared with conventional gasoline with simply added methyl tertiary butyl ether, the alcohol ether-based clean gasoline has a greatly reduced ratio of ether antiknock agents through the addition of relatively small amount of diamine antiknock agents, and an unexpected synergistic enhancement effectis achieved in the aspect of explosion resistance through the combined use of methyl isopropyl ether and ethylene diamine.

Description

Technical field [0001] The invention belongs to the field of petrochemical industry, and relates to a clean fuel, in particular to an alcohol ether-based clean gasoline for vehicles. Background technique [0002] The knocking of gasoline engines is related to the quality of gasoline, such as: gasoline is easy to oxidize, the peroxide formed is not easy to decompose, and the self-ignition point is low. Therefore, the antiknock of gasoline is one of the most important indicators of gasoline quality. The octane rating is the gasoline mark. [0003] Gasoline antiknock agents can be divided into different types according to their chemical properties. At present, the main common ones are: alcohols, ethers, metals and amines. In the prior art, the application of ether anti-knock agents is more popular. MTBE (Methyl Tertiary Butyl Ether) is the main representative. MTBE is produced in most domestic refineries, but it is limited by the high oxygen content and low heating value. , The blen...
