Methanol gasoline additive and preparation method thereof, methanol gasoline including same

Abstract

The invention discloses a methanol gasoline additive and a preparation method thereof, methanol gasoline including the methanol gasoline additive. The additive comprises methyl alcohol, glycerol, isobutanol, isopentane, dimethylbenzene, dimethylbenzene and methylal. The preparation method comprises: preparing the components according to certain weight percentages, adding the components into a container, and stirring uniformly. The methanol gasoline is formed by uniformly stirring the following components in percentage by weight: 42%-48% of methanol gasoline additive and 52-58% of gasoline or solvent gasoline. The additive has the advantages of reasonable formulation, simple component and low production cost. The preparation method of the additive is very simple, convenient and low in cost. The methanol gasoline has excellent performance, and can effectively overcome the technical problems about corrosiveness, swelling property, difficulty in cold boot, heat resistance, delamination upon meeting water and reduced power of the methanol gasoline when methanol content in the methanol gasoline is more than 15%.

Description

technical field [0001] The invention belongs to the technical field of energy and chemical industry, and more specifically relates to a methanol gasoline additive, and also relates to a preparation method of the methanol gasoline additive and a methanol gasoline containing the additive. Background technique [0002] In order to alleviate the pressure brought by the shortage of petroleum resources, alcohol fuel has become a research hotspot as a new alternative fuel. Because methanol has the advantages of easy preparation, wide sources, low cost, little pollution, and can be used in various electric spark ignition engines, methanol gasoline has the broadest application prospects. Methanol gasoline refers to the mixed fuel prepared by mixing methanol, gasoline and specific additives in a certain proportion. Among them, M15 (adding 15% methanol to gasoline) clean methanol gasoline is the most common one. It is used as a vehicle fuel and can be used instead of finished gasoline...

AI Technical Summary

Problems solved by technology

The prepared methanol gasoline is very unstable when stored, and the oleyl alcohol will separate within a few days. The separated methanol gasoline is very corrosive to the car's oil and oil pipes.

Moreover, the price of these additives is generally more expensive, which will increase the production cost of methanol gasoline

[0004] Not only that, the consumption of methanol gasoline is higher than that of gasoline. The high consumption is mainly because its calorific value is lower than that of gasoline, and the low calorific value is due to the fact that methanol gasoline is not fully burned in the engine and has poor combustion performance.
