Description
Technical field
The present invention relates to a kind of fuel oil technology, especially relate to a kind of clean environment firendly type methanol diesel oil.
Background technology
As everyone knows, the ancient biological of inside, tellurian petroleum resources stratum forms through very complicated variation in several hundred million years to tens00000000 years.A large amount of exploitations reduce fast and the subterranean resource of this preciousness is owing to the demand of human development.In China, the Oil extraction amount of several elephants is also fewer and feweri, and consumption is cumulative year after year then.Expect crude oil in China import volume in 2010 and surpass 50% of aggregate demand, need annual expensive more than 40,000,000,000 dollars.A large amount of crude oil imports that rely on not only can't bear the heavy load economically, and seriously jeopardize the energy security of country.
On the other hand, along with various countries' rapid economy development, automobile is also increasing as its demand of a kind of transport facility, the consequent is that vehicle exhaust is then more and more serious to the pollution of atmospheric environment, especially intensive big and medium-sized cities of some vehicles, to the very deleterious tail gas of human health, carbon monoxide (CO), oxynitrides (NOx), the hydrocarbon polymer content in urban atmosphere such as (HC) are more and more higher, and the hazard rating that the ecotope that people are lived causes increases the weight of day by day.
For the consideration to energy scarcity and environmental protection, national governments comprise that China is also more and more higher to the research attention degree of novel automobile substitute energy.
And methyl alcohol is one of primary study exploitation direction of automobile substitute energy as a kind of clean environment firendly energy.In technical study, Sweden in 1975 at first proposes methyl alcohol can become automobile fuel, and after this, states such as the U.S., Germany, Japan, China, Brazil are all in the research of actively developing methyl alcohol substitute energy fields such as relevant methanol gasoline, methanol diesel-oil, methanol fuel.Wherein, the research to methanol diesel-oil is an important subject.
In fact, as the substitute of petroleum resources clean environment firendly still not, also be most economical at China development methyl alcohol.Methyl alcohol is China source chemical resource the most widely, can produce methyl alcohol with minimum cost as coal, Sweet natural gas, coking gas, oil field gas, biomass, production of synthetic ammonia etc.Producing methanol diesel-oil does not only need the fiscal subsidy but also the manufacturing enterprise of country that enough profit spaces are arranged.
But can know that though the research of methanol diesel-oil is very active, methanol diesel-oil exists a series of technical barrier in exploitation, production and engine application, do not capture comprehensively and effectively as yet after the development research data of comprehensive methanol diesel-oil both at home and abroad.The power that adds miscible and lamination problem behind the diesel oil, problem that the methyl alcohol vast scale adds, methanol diesel-oil as: methyl alcohol descends and the velocity shock problem, use in methanol diesel-oil to the etching problem of oil circuit and cylinder and to the corrosion of rubber and plastic spare and swelling problem or the like.These have all limited application, the development of methanol diesel-oil.

In the such scheme: the 102TB corrosion inhibitor is the corrosion inhibiting additive of being produced by granary gloomy eco-friendly power source of crowd company, is the commercially available prod.The 107PT anti-swelling agent is the anti-swelling additive of being produced by granary gloomy eco-friendly power source of crowd company, is the commercially available prod.
1. the present invention has realized that methyl alcohol and diesel oil can be miscible under arbitrary ratio
In the miscible prior art of methyl alcohol and diesel oil, a kind of method is that methyl alcohol is carried out denaturing treatment earlier, and the sex change auxiliary agent of employing has: higher alcohols, benzene class etc. are characterized in that cost is lower but methyl alcohol after the sex change is little to the molecular attraction of diesel oil, layering easily.Another kind of miscible method be heat, under the pressurized conditions, adopt multiple auxiliary agent earlier methyl alcohol to be carried out denaturing treatment, standing and reacting then at normal temperatures and pressures circulates, this method shortcoming is that technology is too complicated, need consume a large amount of energy during reaction, and serialization when producing production capacity low, and production cost is very high.
In the technical scheme of the present invention, chemical reaction will take place after mixing in additive raw material, generate a kind of new material that can disturb the Cloud Distribution of diesel oil.Make the chemical bond bond angle between carbon atom and the hydrogen atom be offset (＜180 °), the bond angle skew is big more, and the positive charge of hydrogen atom is big more to the gravitation of other polar molecule, and its polarity is also strong more.With after diesel oil mixes, can carry out denaturing treatment to diesel oil, make it have very strong molecular attraction, to realize that methyl alcohol and diesel oil can be miscible under arbitrary ratio to methyl alcohol.And storage test shows, but after miscible more than the prolonged preservation to three year.
2. the present invention has realized that the vast scale of methyl alcohol in diesel oil adds, and improves power.
Because the adding of methyl alcohol is increased the heat of gasification (being vaporization heat) of fuel, thereby has been increased from the delay period of the rapid combustion of lighting a fire, incendiary maximal pressure force is lagged behind, can cause the decline of engine power.
In the technical solution of the present invention, its mixed additive absorbs a part of heat on the one hand when methyl alcohol and diesel oil are miscible, to reduce vaporization heat; The combustionvelocity of fuel is accelerated, thereby methanol fuel is overlapped as much as possible with the maximal pressure force of diesel oil when burning, with the maximum transfer power of performance fuel.
3. another big characteristics of the present invention are that dynamic curve is compensated.
Because single boiling point characteristic of methyl alcohol in the fuel, in fuel, add a large amount of methyl alcohol after, boiling range curve substantial deviation the original boiling range curve of diesel oil.In order to address this problem, adjust the boiling range curve, contain the boiling range scope in the technical scheme of the present invention at 100～135 ℃ raw material.Make fuel meet the demand of the whole combustion processes of diesel engine substantially.
4. technical scheme of the present invention efficiently solves etching problem.
Methanol diesel-oil can produce organic acid (formic acid etc.) material in combustion processes, to the corrosion of engine cylinder.Contain the organic bases composition in the technical scheme of the present invention, it is produced in burning and material generation neutralization reaction such as formic acid; Simultaneously, technical scheme of the present invention can also generate high temperature resistant oil film protection cylinder wall in the fuel high-temp combustion.In addition, also because the technical scheme of the present invention composition of containing benezene material not makes fuel not have corrosion and swelling problem to the metalwork in the oil circuit, rubber parts, plastic component.
Manufacture method of the present invention: above-mentioned raw materials with the prescription metering, is mixed at normal temperatures and pressures, is the public oil product compounding method of routine.Can be with reference to Fig. 1 mode, quantitatively add in the line mixer respectively by pump of constant delivery type, under meter and mix being stored in above-mentioned formula material in each storage tank, make the finished product methanol diesel-oil.

2. the content of fuel nuisance is few
After testing: methanol diesel-oil of the present invention, its lead content, sulphur content, benzene content, aromaticity content, olefin(e) centent all are significantly smaller than the standard value of ordinary diesel oil.Wherein, especially benzene and polyphenol aromatic hydrocarbons all are carcinogenic Toxics, from the significantly minimizing of these two kinds of materials and, the environmental protection effect of this fuel can be significantly found out in the significantly minimizing of lead content, sulphur content.
3. anti-oxidant and security
Far away be higher than general standard up to＞3000min the inductive phase of clean environment firendly type methanol diesel oil of the present invention; Be the important indicator of evaluation vehicle fuel antioxygen and stability inductive phase, can show that this fuel produces oxidation and forms the gelationus index between the shelf lives.Inductive phase is long more, represents that this fuel oxidation stability is good more.The existent gum of methanol diesel-oil of the present invention is 2mg/100ml, and much smaller than general standard, this result further illustrates the oxidation-resistance and the stability of methanol diesel-oil of the present invention again.
4. sufficient combustion
The oxygen level of methyl alcohol is up to nearly 50%, its adding makes fuel become a kind of high oxygenated fuel, fuel has become in combustion processes and has a kind ofly burnt from oxygen supply burning and the dual oxygen supply of outer oxygen supply incendiary, and the burning of ordinary diesel oil can only depend on outer oxygen supply burning, therefore the burning of methanol diesel-oil is inevitable more fully, more thorough, reduces amplitude (having reduced 80%) from carbon monoxide emission and can significantly find out its incendiary adequacy.So just reduce the discharging of nuisance in the tail gas widely, because the reduction of hydrocarbon emission makes the carbon distribution in the engine cylinder also have tangible minimizing, increased the work-ing life of engine simultaneously.
5. protection engine
Because contained an amount of engine protection composition in the clean environment firendly type methanol diesel oil of the present invention, under engine full power full load continual test in 200 hours, the numerical value that output rating descends is starkly lower than the decline standard of ordinary diesel oil.Therefore, this fuel is conspicuous to work-ing life and the protection characteristic that prolongs engine.
6. production technique is simple
Production Flow Chart technology is simple, the normal temperature and pressure operation, and full-automatic computer control, 24 hours continuous production only need 4-5 people's operation, save the labor force, reduce labour intensity.Investment goods is low, and floor space is little, and contamination-free produces.
