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

虽然现有技术中已公开了多种解决方案,如中国专利CN1332227、CN1364856、CN1371963、CN1381551、CN1410520、CN1429893、CN1487060、CN1508234、CN1521243、CN1563287、CN1580204、CN1712501、CN1727452、CN1743432、CN1754948、CN1821359、CN1821360、 CN1827751, CN1876775, CN1884448, CN1884449, CN1891794, CN1923977, CN101012394, CN101012395 and CN101012398, but the above-mentioned technical solutions either failed to solve the delamination problem well, or added too many additives, which made the process complicated and the emission of harmful gases increased , Increased coking after combustion or the use of additive sources are in short supply or banned, making it difficult to form mass production; either the storage is unstable, combustion and emission are difficult; or the corrosion degree of the engine oil supply system is enhanced; Transformation; or there are a series of problems and defects such as high cost, poor anti-knock performance, poor energy-saving effect, excessive exhaust emissions, or inability to mix with other oil products. Therefore, methanol gasoline for vehicles has not been popularized and applied, and people urgently need it Solve a kind of methanol gasoline for vehicles that can be mass-produced, high-clean, high-environmental protection, high-performance and low-cost
