Description
Technical field
The invention belongs to the organic-fuel technical field of new forms of energy, be specifically related to a kind of method for formulating of high energy organic-fuel of alternative diesel oil.
Background technology
As everyone knows, because the pollution that the global shortage of petroleum resources and automobile use diesel oil to cause increasingly sharpens, countries in the world are all attempting utilizing other chemistry, physics and bioenergy to substitute diesel oil.The Oil Safety and the environmental issue of China are on the rise, and pay attention to more to substitute wholly or in part diesel oil with new forms of energy.In dropping into the various solutions of research, methyl alcohol substitutes diesel oil becomes first-selection.This is prone to fully burning not only because the methyl alcohol octane value is high, and is cheap, and the coal resources that can make full use of China's abundant are to carry out mass production.But the trial of adopting methyl alcohol to substitute diesel oil is fully never succeedd, and its subject matter is: the one, and the low heat value of methyl alcohol (having only 21000KJ/Kg), low-calorie half the less than diesel oil, dynamic property is relatively poor during use, and has the problem of cold start-up difficulty; The 2nd, methyl alcohol is prone to make rubber and the plastics swelling on the diesel vehicle component, thereby causes the swelling thing to stop up oil circuit; The 3rd, methyl alcohol produces formaldehyde and formic acid when imperfect combustion, and the latter possibly cause corrosion to automobile component.In promoting the use of the process of methyl alcohol, avoid the generation of the problems referred to above; The solution of taking both at home and abroad mainly is that thereby part is added a certain proportion of methyl alcohol acquisition methanol diesel-oil emulsion fuel or microemulsion fuel in diesel oil; But the methanol content in the fuel of these emulsifications and microemulsified is lower; Standing storage lower leaf problem does not solve fully, thereby all fails to obtain production and apply.From prior art, occur at present fully without diesel oil on the domestic and international market as yet and can substitute the organic-fuel of diesel oil fully, there is not this type of organic-fuel of pertinent literature public reported yet.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art; And provide that a kind of calorific value is high, cold starting property is good, swelling property is little, cost is low, erosion resistance is strong, leave standstill the high energy organic-fuel that can substitute diesel oil fully of good stability, and corresponding a kind of aforementioned method for formulating that can substitute the high energy organic-fuel of diesel oil fully is provided.
