Vehicle high-methanol content gasoline

Abstract

The invention discloses vehicle high-methanol content gasoline, relates to carbon-containing fuels and solves the problems of difficult low-temperature startup, serious metal corrosion, inadequate power and susceptibility to generating precipitates of the conventional methanol gasoline. The vehicle high-methanol content gasoline comprises the following components in part by volume: 70 to 86 partsof methanol, 14 to 30 parts of gasoline component oil, 0.5 to 1 part of cosolvent, 0.1 to 0.2 part of antiseptic and rubber swelling inhibitor, 0.2 to 0.3 part of detergent and 0.01 to 0.05 part of coloring agent. The cosolvent consists of isobutanol, isopropyl ether, 2-isobutanol and tetrahydrofuran, the antiseptic and rubber swelling inhibitor consists of propargyl alcohol, butanedioic acid, hexakis(dihydrogen phosphate), N-methyl morpholine, cyclohexane and dimethyl phthalate, the detergent consists of normal propyl alcohol, isopropanol, limonene and cyclohexane, and the coloring agent is Sudan IV solution. The vehicle high-methanol content gasoline has high startability, high dynamic performance, high environmental protection performance, obvious anticorrosion effect and high safety.

Description

technical field [0001] The invention relates to liquid carbon-containing fuels, in particular to a high-proportion methanol gasoline for vehicles. Background technique [0002] Automobile fuel consumption has become an important part of my country's oil demand, and our country relies on importing a large amount of crude oil every year to supplement the gap between oil supply and demand. In order to ensure the healthy development of the automobile industry, in addition to petroleum-based fuels, it is urgent to seek a stable, durable, economical, convenient and clean vehicle fuel to supplement and partially replace petroleum fuels. [0003] Combining my country's national conditions of "lack of oil, less gas and rich coal", the development of coal-based alcohol ether fuels to replace gasoline and diesel can greatly reduce my country's dependence on oil imports, and alcohol ether fuels are economical and environmentally friendly as alternative fuels for vehicles.
