AI Technical Summary

Problems solved by technology

The flash point of methanol is very low, only 12°C. If methanol vapor accumulates in a closed space, a weak spark can ignite, posing a great safety hazard
At the same time, the evaporation of a large amount of methanol will also reduce the quality of oil products and cause waste

Abstract

The invention provides an alcohol-based fuel which comprises paraffin oil and a component, wherein the component is formed by mixing the following ingredients in percentage by weight: 70-98% of methanol, 0.1-28% of water 1.5-4.5% of glycerol, 0.2-1% of ammonia-ammonia chloride buffer solution, and 0.05-2% of 1-hydroxyethylidene-1,1-diphosphonic acid; the alcohol-based fuel is separated into two layers under a standing condition, and the paraffin oil is positioned on the surface layer. The paraffin oil in the alcohol-based fuel provided by the invention is positioned on the surface layer of the alcohol-based fuel to form a liquid film to isolate methanol from contacting with the air, so that methanol volatilization is inhibited, and the aim of improving the flash point is achieved. Furthermore, the 1-hydroxyethylidene-1,1-diphosphonic acid in the alcohol-based fuel plays a role in retarding the alcohol-based fuel to corrode contacted equipment.

Description

Technical field [0001] The invention involves a alcohol -based fuel, which specifically involves a alcohol -based fuel with high flash point and can reduce equipment corrosion. Background technique [0002] Methanol (alcohol) fuel refers to a type of liquid fuel containing methanol.Methanol is a very low stability and is very easy to volatile flammable liquid. When the temperature is 64 ° C, the methanol can change from the liquid phase to the gas phase, that is, the methanol steam.The symptoms of headache and chest tightness are very harmful to the human body.The flash point of methanol is very low, only 12 ° C. If the methanol steam accumulates in a closed space, the weak Mars can be ignited, and there are great safety hazards.At the same time, a large amount of methanol evaporation will also reduce the quality of oil and cause waste.Therefore, methanol fuel must change the nature of methanol into the nature of the methanol to make the alcohol -based fuel, so that it is more st...
