yes.
Analysis shows that methanol fuel is a new clean fuel made of industrial methanol or fuel methanol, denatured alcohol additive, and existing national gasoline and diesel oil (or component oil) by strict scientific process according to a certain volume (or weight ratio). It can replace gasoline and diesel oil and be used in various motor vehicles and stoves. The raw materials for methanol production are mainly coal, natural gas, coalbed methane, coke oven gas, etc., especially high-sulfur inferior coal and coke oven gas. It can not only improve the comprehensive utilization of resources, but also reduce environmental pollution. Developing coal-based methanol fuel to supplement and partially replace petroleum fuel is an effective shortcut to alleviate the energy shortage in China, improve the comprehensive utilization of resources and protect the ecological environment.
Characteristics and application of methanol as a substitute fuel:
Because methanol has the characteristics of low boiling point and high octane number, it has the characteristics of high oxygen content and weaker calorific value than gasoline as a fuel. The latent heat of vaporization is more than three times that of gasoline. At the same time, because the physical and chemical properties of methanol fuel are close to that of gasoline, the engine does not need to be greatly changed when methanol fuel is used in gasoline, and methanol and gasoline have good compatibility and can be blended in various proportions. Moreover, a device with several hundred thousand tons/year can reach economic scale (synthetic oil should reach at least several million tons/year), and methanol can be produced without excessive concentration, which is convenient for enterprises to invest and build and transport products, even if it is transported for a long distance. It is also more convenient than coal and gas transportation. In addition, it is an oxygen-containing compound, which burns completely, and its energy utilization efficiency in automobile engines is higher than that of gasoline, so its economy is very competitive.
The use of methanol fuel in gasoline engines has gradually developed from low-proportion blended combustion (M15 methanol accounts for 15%) to high-proportion blended combustion (M85～M111) in the late 1981s. It has also gone through a rather difficult process. The United States began to develop a flexible fuel vehicle (FFV) in 1987, which can be applied to methanol, gasoline, and the mixture of gasoline and methanol. Japan does not engage in a special methanol vehicle (FFV). At present, after decades of research and development, the technical problems have been basically solved.
The combustion characteristics of methanol have two major characteristics: First, excellent cooling effect. Second, it has extremely high antiknock ability, and can burn at a pressure higher than that allowed by high-quality gasoline without knocking. This is just suitable for engines with high compression ratio and high performance. It gives full play to its high octane number and outputs more power. Of course, methanol also has weaknesses. Its energy is low, and its consumption for driving the same distance is almost twice that of gasoline, so it needs a large fuel tank.
The advantages of methanol are complete combustion, low volatility and hydrocarbon emissions.
