Description

Vehicular methanol petrol

Technical field

The present invention relates to a kind of Vehicular methanol petrol and compound method thereof, belong to the petrochemical technology field.

Background technology

World's methanol fuel for vehicles exploitation and application start from the oil crisis second time of the seventies in 20th century, consider that from the angle of substitute energy states such as Germany, the U.S., Japan successively drop into the research and development that human and material resources carry out methanol fuel and methyl alcohol supporting technology.China's methanol fuel is used for the experimental study of automobile mainly to be carried out in producing coal Da Sheng Shanxi, from early 1980s so far, the Shanxi Province has obtained bigger progress under the support of departments such as former State Economic and Trade Commission, the State Scientific and Technological Commission, planning commission.During " six or five ", State Scientific and Technological Commission, the Ministry of Communications and Shanxi Province have carried out mixing promoting the use of of burning 15%～100% methyl alcohol (being called for short M15 and M100) in vapour, diesel oil, organize 475 medium truck demonstration operations, accumulative total stroke 8,000 ten thousand kms are obtained good result.The enforcement period of the ninth five-year plan, State Scientific and Technological Commission organizes U.S. Ford Motor Company, the Chinese Academy of Sciences, the Ministry of Chemical Industry, Shanxi Province, Tsing-Hua University etc. that coal system methyl alcohol has been done " 3E " (energy, economy, environmental protection) life cycle research, and conclusion is " is feasible at the area of middle national wealth coal oil starvation development methanol fuel and methanol vehicle ".But existing production technology ubiquity following not enough, needs to be resolved hurrily:

1, corrodibility is strong: methyl alcohol has certain corrodibility.Have stronger chemically reactive, can corrode aluminium, lead, manganese, plastics, synthetic rubber etc., and these materials are typical materials of Fuel Petroleum automobile.In addition, alcohol is all stronger than independent alcohol or gasoline to the swelling action of rubber, plastics with the propellant combination of gasoline;

2, calorific value is low: the calorific value of methyl alcohol has only 48% of gasoline, the same mileage that travel, and it is big that required fuel space is wanted;

3, easily produce vapour lock: the boiling point of methyl alcohol has only 65 ℃, under the engine normal working temperature, is easy to produce vapour lock, fuel feed is reduced even the interruption fuel feeding;

4, vaporization heat is big: the vaporization heat of methyl alcohol is more than 3 times of gasoline, and the vaporization heat conference makes methyl alcohol class A fuel A cold-starting and cold operation mis-behave;

5, easily layering: the stability of methanol gasoline depends primarily on the moisture in the mixed solution, and when moisture reached certain content, methyl alcohol can separate from base oil.

Summary of the invention

The objective of the invention is deficiency, a kind of energy-saving and environmental protection, Vehicular methanol petrol efficiently are provided at prior art.

Technical scheme of the present invention is:

A kind of Vehicular methanol petrol is made of by weight ratio following raw material

Methyl alcohol 10%～80%, ethanol 2%～15%, base oil 5%～30%, white gasoline 10%～80%, ethylene glycol diethyl ether 0.1%～2.0%, methyl glycol 0.1%～2.0%, isopropylcarbinol 0.1%～2.0%, Virahol 0.1%～2.0%, n-propyl alcohol 0.1%～2.0%, butanone 0.1%～2.0%, hexanaphthene 0.1%～0.5%, octane 0.1%～2.0%, 2,6 ditertiary butyl p cresol 0.1%～2.0%.

Above-mentioned raw materials proportioning of the present invention is to increase and decrease adjustment according to the variation of seasonal temperature and the difference of base oil.Described base oil can be selected any or multiple mixtures such as carbon five, petroleum naphtha, sherwood oil for use.

Preparation method: at normal temperatures and pressures, circulated 1～2 hour, above-mentioned raw materials is fully concocted by proportioning evenly be finished product by reactor stirring 30 minutes or in-line pump.

Advantage of the present invention and characteristics:

1, energy-conservation; Methyl alcohol can be produced from Sweet natural gas, oil, coal, timber and allogenic material thereof, and wherein producing methyl alcohol from coal has sufficient resource guarantee in China, produces methyl alcohol from biomass and has recyclability.The addition of methyl alcohol of the present invention is up to 80%, thereby has reduced vehicle to consumption of petroleum resources, helps energy security and has reduced cost;

2, environmental protection: oxygen level of the present invention is higher, and burning has significantly reduced the discharging of HC fully, and because of H/C is big, its CO quantity discharged obviously reduces, and belongs to clean fuel.Help reducing topsoil, the protection environment;

3, efficient: the present invention has overcome fundamentally that the ubiquitous corrodibility of prior art is big, calorific value is low, has easily produced vapour lock, vaporization heat is big, easy shortcoming such as layering, vehicle can directly use, also can mix use with GB gasoline, octane value height (RON), dynamic property are strong, safe and efficient.
