Abstract

The invention discloses methanol gasoline composite additive and the preparation method; the composite additive comprises the raw materials of isopropyl alcohol, isobutyl alcohol, isoamyl alcohol, 2-ethyl (1) hexanol, cleaning dispersing agent, petroleum ether, isopropyl ether, tetralin, zinc naphthenate, dimethyl formamide, methyl tert-butyl ether, tween-60 and PTFE, and is prepared through the steps of mixing according to weight ratio, adding the ingredients sequentially according to the process steps, stirring, heating, compression, stirring, stationary standing and discharging the sediment; thereby the composite additive is obtained. The menthol gasoline prepared by the composite additive in the invention has the advantages of increasing the content of the methanol, good power performance, good separation resistance, anticorrosion property and low temperature starting performance, good oil saving effect, prolonging the service life of the engine and reducing the discharge of the harmful gas in the vehicle tail gas obviously.

Description

technical field [0001] The invention relates to a methanol gasoline composite additive and a preparation method thereof. Background technique [0002] Due to the rapid development of the current economy, the demand for energy is increasing day by day, especially the demand for motor vehicle fuel is growing faster, and the limited oil reserves and extractions are difficult to meet the growing needs of society. In order to use existing resources to supplement and replace petroleum, people have gradually developed some fuel products that supplement and substitute petroleum. For example: Methanol gasoline is prepared by mixing and dissolving methanol and gasoline in a certain proportion, under the action of the main solvent and synthetic additives, and a certain amount of methanol is used to replace gasoline in methanol gasoline. At present, the content of methanol in methanol gasoline in domestic provincial standards is about 15%, and the content of gasoline is more than 85%....
