Clean alcohol fuel

Abstract

The invention is an alcohol clean fuel, which is composed of methanol, ethanol gasoline component oil, isopropanol, combustion accelerator, cleaning and dispersing agent, anticorrosion inhibitor, metal passivator, anti-icing agent, antioxidant, stabilizer Agent and antiknock agent can be prepared into the required fuel by mixing evenly. The fuel of the present invention can be used alone in vehicles, and can also be mixed with any proportion of national standard unleaded gasoline, and is suitable for various vehicles with gasoline engines, without any modification to the engine; the fuel of the present invention is conducive to environmental protection , can effectively reduce the discharge of harmful substances such as CO, CH and NOx compounds in automobile exhaust: the fuel of the present invention does not corrode metals such as aluminum, cast iron and steel, and the swelling phenomenon of plastic parts is lower than that of unleaded gasoline. In addition, the fuel of the invention has wide source of raw materials, simple production method and low production cost, and is a clean fuel with broad market prospect.

Description

technical field [0001] The present invention relates to liquid fuel, more specifically, it is a kind of green and environment-friendly alcohol blended with methanol, ethanol and low-octane gasoline components as main raw materials, supplemented with additives to improve performance Class clean fuel. Background technique [0002] In recent years, with the rapid development of my country's national economy, my country's demand for refined oil has been increasing. For example, in 2001, the consumption of motor gasoline reached 40 million tons, of which 15 million tons were imported, accounting for the total consumption of motor gasoline. 37%. With the development of the economy and the improvement of people's living standards, the amount of social vehicles and civilian vehicles will increase rapidly. Some experts predict that the annual growth rate of gasoline demand in 2005 can reach 4.4%. Gasoline consumption will reach 43 million tons. Since 1994. my country has become a ...

Problems solved by technology

After 10 years of research and development, some technologies have made breakthroughs, but some technical difficulties still need to be further resolved, such as the low calorific value of methanol gasoline; the oxygen content of methanol is as high as 50%, and the air-fuel ratio (kg air / kg gas) is low. It is difficult to adapt to the engine of ordinary automobiles; a small amount of formaldehyde or formic acid is produced after methanol combustion, so it has certain corrosion and swelling properties (such as patent number: 01129356.x, an alcohol-based clean fuel composition and its preparation method)
