Description
Technical field
The present invention relates to the preparation method of a kind of composite additive and methanol diesel-oil thereof
Background technology
The development substitute energy is the guarantee national energy security, alleviates petroleum import pressure, alleviates the great strategic measure that resource environment retrains.The Party Central Committee, State Council pay much attention to this, and the party and state leaders once repeatedly made important written instructions.According to the Scientific Outlook on Development, make overall planning, give top priority to what is the most important, go ahead in a down-to-earth manner, strengthen the substitute energy scientific research and development, accelerate the industrialization paces, make great efforts to provide the energy safeguard of cleaning, safety, economy, sustainable supply for socio-economic development.
For many years, the research and development production of methanol fuel rises and falls with promoting the use of several times, has been fast rise trend at present.Facts have proved, can be used as in the vehicle alternative fuel multiple, the methanol fuel technology maturation, economically feasible, environmental friendliness, safe and reliable, imperative, have a extensive future.To industry restructuring, comprehensive utilization of resources, improve the ecological environment, realize that recycling economy has positive promoter action.
Is that the diversification exploitation is carried out on the basis with the coal, gives priority to alcohol-ether fuel and be the major subjects of " substitute energy " developmental research in recent years.The project of this problem, actively developed the experimental study and the regional industrial demonstration operation of the alternative gasoline of methanol fuel in the existing many provinces of China, area, city as focus development and research, respond well, fruitful.In the provinces and cities of many development researches, popularization operation, the approach that coal-based alcohol ether fuel substitutes petroleum-based energy is adhered to walking as the landlocked province of relative oil starvation, weak breath, rich coal in Shanxi, and the Sustainable development of recycling economy is realized in construction novel energy and industrial base.In recent years, Tenth Five-Year Plan Period particularly in the whole nation is that the methanol fuel industrialization demonstration operation of representative has reached a new level with the Shanxi Province.Shanxi Provincial Party Committee, provincial government grab Developing Fuel Methanol and cleaning (methyl alcohol) automobile as a strategy job, and to have set up be leader's group of group leader with governor.Since calendar year 2001, the Shanxi Province has formulated policy, the standards and norms that a series of methanol fuels are applied, and general office of provincial people's government repeatedly issues the documents, and segmentation is disposed, and deeply, promotes the use of methanol fuel in the whole province layer by layer.The attention of provincial government of Provincial Party committee and support make substantial progress this novel energy industry of methanol fuel, have taken the lead in starting the epoch of batch automobile with " methyl alcohol " in the whole nation to Shanxi Province in 2006.This shows that development has the china natural resources advantage, has the coal-based alcohol ether fuel and the automotive industry of China's independent intellectual property right, prospect is very wide.Therefore people have invented multiple methanol diesel-oil, though these technology kinds are a lot, but in experiment and experimentation, still there is following problem: the methanol diesel-oil unstable properties, the easy emulsification of water breakthrough, the cold-starting difficulty, the high temperature vapour lock, methyl alcohol does not have fine solution to corrosion of metal with to the swelling property of rubber, the methyl alcohol mixed-fuel burning proportion is low generally to have only 5%---and 10% causes the production cost height, promotes problems such as difficulty.
Summary of the invention
