Problems solved by technology

However, due to the nature of methanol gasoline with strong polarity and low calorific value, the methanol gasoline formed in this way will become turbid and phase-separated when it encounters water and low temperature during use. It cannot be used normally and has low calorific value. Corresponding increase in fuel consumption
In the use of methanol gasoline, it is difficult to ignite in winter, and it is easy to have the defect of air lock in summer

Abstract

The invention discloses an additive for improving resisting phase separation performance and a heat value of methanol gasoline. The additive consists of the following raw materials in percentage by weight: 35-45 percent of aliphatic alcohol, 10-20 percent of aliphatic ether, 15-30 percent of aliphatic ester, 5-15 percent of aliphatic acid, 1-5 percent of aliphatic amine and 0.1-3 percent of emulsifier OP, wherein the aliphatic alcohol is one or more of isopropyl alcohol, n-propanol, n-amyl alcohol, isoamyl alcohol and n-butyl alcohol; the aliphatic ether is one or more of ethylene glycol methyl ether, ethylene glycol ethyl ether and ethylene glycol butyl ether; the aliphatic ester is one or more of butyl acetate, n-amyl acetate and isoamyl acetate; the aliphatic acid is oleic acid and/or naphthenic acid; the aliphatic amine is dimethylamine and/or diethylamine; and the emulsifier OP is emulsifier OP-15 and/or emulsifier OP-20. The methanol gasoline in which the additive is added has superior low-temperature resisting phase separation and water resisting phase separation performances and an obviously improved heat value.

Description

technical field [0001] The invention belongs to the technical field of methanol fuel, and in particular relates to an additive for improving the phase separation resistance and calorific value of methanol gasoline. Background technique [0002] Methanol has a wide range of sources, mature production technology, and low cost, and can be used as a clean fuel for vehicles. Experiments have proved that anhydrous methanol can be miscible with commercial gasoline in any proportion, and can form clear liquid methanol gasoline. However, due to the nature of methanol gasoline with strong polarity and low calorific value, the methanol gasoline formed in this way will become turbid and phase-separated when it encounters water and low temperature during use. It cannot be used normally and has low calorific value. The fuel consumption ratio increases accordingly. In the use of methanol gasoline, it is also difficult to ignite in winter, and the defect of air lock is prone to occur in s...
