Abstract

The invention relates to an additive of a high-clean methanol gasoline and a preparation method thereof. The additive is prepared by mixing the following raw material components in parts by mass: 15-30 of ethanol, 10-20 of isopropyl ether, 1-9 of dimethyl carbonate, 1-15 of acetone, 0.1-6 of dimethyl ketone, 0.5-8 of isopropanol, 1.5-10 of tertiary butanol and 1-8 of iron naphthenate; the raw material components in the additive also comprise one, two or more of the following ingredients in parts by mass: less than or equal to 10 of isooctane, less than or equal to 9 of diethyl ether, less than or equal to 10 of methyl tertiary butyl ether, less than or equal to 8 of ethyl acetate and less than or equal to 7 of aluminum phosphate or sodium dihydrogen phosphate. The additive is prepared by mixing the raw materials. The additive of the methanol gasoline in the invention has good safety and is environmentally -friendly; by using the additive, the problems of immiscible, corrosion, air resistance, swelling and the like in the preparation process of the additive of the methanol gasoline are solved; and the preparation process is simple and convenient. The additive can be used for preparing the methanol gasoline for various vehicles, wherein denatured alcohol accounts for 10%-20% by weight of the methanol gasoline.

Description

technical field [0001] The invention belongs to petrochemical products, in particular to a methanol gasoline additive and a preparation technology thereof. Background technique [0002] With the rapid development of my country's economy, the development and consumption of petroleum resources are intensifying. According to reports, in my country's entire oil consumption, the consumption of gasoline and diesel exceeds 50% of the total energy consumption, of which transportation fuel accounts for more than 70%. In the development and research of many automobile fuels, alcohol-based fuels are considered to be the most promising alternative clean fuels for automobiles due to their excellent quality, among which methanol fuels are the first choice. Methanol as an alternative energy has many advantages: first, methanol has a wide range of sources, and the development of methanol fuel has good economic benefits and can drive the development of related industries; second, methanol g...
