Methanol gasoline for vehicle

Abstract

This invention relates to a car-used methyl alcohol gasoline and its preparation method. The gasoline is composed of following raw materials in terms of weight proportion: methyl alcohol 10-80%, alcohol 2-15%, basic oil 5-30% lead-free gasoline 10-80%, ethylene glycol diethyl ether 0.1-2.0%, ethylene glycol diethyl ether 0.1-2.0%, ethylene glycol monomethyl ether 0.1-2.0%, isobutanol 0.1-2.0%, isopropanol 0.1-2.0%, 1-propanol 0.1-2.0% and 2.6-2-tert-butyl-p-cresol 0.1-2.0%.

Description

technical field [0001] The invention relates to methanol gasoline for vehicles and a preparation method thereof, belonging to the technical field of petrochemicals. Background technique [0002] The development and application of methanol fuel for vehicles in the world began with the second oil crisis in the 1970s. From the perspective of alternative energy sources, Germany, the United States, Japan and other countries have successively invested manpower and material resources in the research and development of methanol fuel and methanol supporting technologies. . The experimental research of methanol fuel used in automobiles in my country is mainly carried out in Shanxi, a major coal-producing province. Since the early 1980s, Shanxi Province has made great progress with the support of the former State Economic and Trade Commission, Science and Technology Commission, and Planning Commission. During the "Sixth Five-Year Plan" period, the National Science and Technology Commi...

AI Technical Summary

Problems solved by technology

[0004] 2. Low calorific value: The calorific value of methanol is only 48% of that of gasoline. To travel the same mileage, the required fuel volume is larger;

[0005] 3. Air resistance is easy to occur: the boiling point of methanol is only 65°C. Under the normal operating temperature of the engine, it is easy to generate air resistance, which reduces the fuel supply or even interrupts the fuel supply;

[0006] 4. Large latent heat of evaporation: the latent heat of evaporation of methanol is more than three times that of gasoline, and the latent heat of evaporation will deteriorate the low-temperature start-up and low-temperature operation performance of methanol-based fuels;
