Methanol gasoline for vehicle

Abstract

The invention discloses an energy-efficient, environment-friendly and high-efficient and low-cost automobile methanol gasoline. The methanol gasoline consists of (calculated by weight percent) gasoline (20-48 percent), methanol (30-70 percent), light hydrocarbon (5-15 percent) and additives (5-7 percent); the additives in the automobile methanol gasoline consists of (calculated by weight percent) solubilizer (1.5-5 percent), anti-oxidant (0.05-0.2 percent), antifreezing agent (0.5-1.0 percent), heat-value increasing agent (0.5-1.0 percent), plasticizer (0.05-0.5 percent), antioxidant (0.05-0.2 percent), stabilizer (0.2-0.8 percent) and antiseptic agent (0.2-1.0 percent). The raw materials required by the automobile methanol gasoline are available from extensive resources and the price is low; suitable for mass production and the production process is very simple; besides, the production is not restricted by seasons or scale.

Description

technical field [0001] The invention relates to methanol gasoline for vehicles and belongs to the technical field of alcohol-based fuels for vehicles. Background technique [0002] At present, the production of gasoline, which is an essential fuel required for the operation of automobiles, is obtained by refineries using petroleum as raw material through multiple processes under relatively complex processes and corresponding equipment conditions. Because the oxygen content in this kind of gasoline is low, the combustion in the engine is insufficient, and the content of lead, CO and CH in the discharged tail gas is higher, pollutes people's living environment seriously. In order to solve the above problems, people have changed the process to produce unleaded gasoline. Although the environmental pollution has been improved after application, its production cost has increased significantly, especially the production cost of low-olefin gasoline has increased even more, making it...

AI Technical Summary

Problems solved by technology

Alcohol-based fuels are the most studied in the prior art, such as ethanol gasoline and methanol gasoline. Since ethanol is extracted from food, although it is a renewable resource, many countries in the world have conflicts in terms of arable land and food resources. Moreover, when ethanol gasoline fuel is used, it is easy to produce carbon deposits and affect the service life of the engine, so it is not feasible to use ethanol gasoline as a substitute for existing gasoline

In recent years, methanol gasoline has gradually attracted everyone's attention as a vehicle fuel. This is because methanol has high oxygen content, good volatility, large latent heat of vaporization, wide range of sources, low production cost, good combustion effect, and low environmental pollution. It is considered to be a better substitute for gasoline, but the R&D and production of methanol gasoline, especially high-content methanol gasoline, will face the following technical problems: 1) strong corrosion; 2) low calorific value; 3) easy to produce air lock ; 4) Large latent heat of evaporation; 5) Easy to stratify
