Description
Technical field
The present invention relates to clean energy technology field, more particularly to a kind of clean fuel oil and preparation method thereof.
Background technology
Under the present situation of global energy shortage, " energy-conservation " and seek alternative energy source, it has also become world's sustainable development is most existing
Real selection.Methanol diesel-oil is paid close attention to by more and more extensive as a kind of cheap, cleaning fuel.Methanol diesel-oil is bavin
The fuel that oil, methyl alcohol and additive are allocated by certain volume or mass ratio by certain flow.Methanol diesel-oil
Using can both save petroleum resources, reduces cost, air pollution can be reduced again, be a kind of novel energy of environment-protecting clean, be subject to
Extensive concern.But, methanol diesel-oil to the swellability and the corrosivity to engine metal part of engine fuel oil system,
And the intermiscibility of methyl alcohol and diesel oil itself significantly limit the application and popularization of methanol diesel-oil.
Methanol diesel-oil exist these not enough main causes be methyl alcohol as a kind of highly polar organic solvent, its to iron,
The metals such as copper, aluminium have corrosivity.In practice, the corrosivity of methanol diesel-oil is before combustion, burning is neutralized after burning body
It is existing.Before burning to oil tank, fuel charger, pipeline, car fuel tank, the oil circuit of oil feeding system, pump, filter, nozzle have corrosion, long
Invade bubble, metal iron filings etc. of time come off and block oil supply system, cause oil supply system to be obstructed, and influence fuel feeding.In combustion process
It is more serious with high temperature gaseous corrosion with the increased wear of casing wall to piston in cylinder body, cause to change the ring on piston in advance.Burning
Corrosion to gas extraction system afterwards has yellow-red liquid to discharge, and causes exhaust system component to change in advance, and methanol content is bigger
Corrosion phenomenon is more serious.Methanol diesel-oil is mainly reflected in it to the swellability of plastics makes the little particle generation in plastics swelling and de-
Fall, for the oil supply system of plastic products, including the plastic components in fuel charger, be easily caused small particle block oil supply system or
Oil leakage phenomenon.Oil circuit inwall, fuel tank, the greasy dirt of inner wall of oil tank long term accumulation to oil supply system, corrode and issue for a long time in methyl alcohol
Raw electro-chemical reaction, produces cleaning action, causes these greasy dirts to come off into the forms such as little particle, blocks pump, the filtering of oil supply system
Device, nozzle etc., cause fuel feeding not smooth, serious interruption fuel feeding, this be due to methyl alcohol in super property material it is anti-to these objects
Adsorbing contaminant is produced during answering and produces what iron hydroxide phenomenon was caused.
These problems that methanol diesel-oil is present greatly constrain the practical application of clean fuel oil.Methyl alcohol in methanol diesel-oil
Content it is bigger, these problems are more prominent.

Using having quite excellent anti-swell rubber in clean fuel oil, a small amount of use can substantially reduce oil product to rubber to two acid esters
The swelling action of glue.
The above one line heavy diesel fuel of decompression is the first vacuum side stream in oil vacuum distillation process, and density is 0.88-0.96
㎏/cm3.The density of clean fuel oil is adjusted by depressurizing a line heavy diesel fuel.
The above biodiesel is C12-18Fatty acid methyl ester.
Biodiesel has structure similar to mineral diesel, can fully be dissolved each other with diesel oil, while having Cetane number high
(60), many advantages such as flash-point (be 130 DEG C) high, calorific value (9500 kilocalorie) high, directly can make instead of diesel oil or mix with diesel oil
With the thermal efficiency of diesel oil can be improved, it is ensured that the abundant burning of diesel oil, simultaneously as the biodiesel not material such as sulfur-bearing, nitrogen,
Sulphur, nitrogen and carbon emission amount can be significantly reduced.The biodiesel used in the present invention mainly discards oil plant (waste oil) with dining table
Raw material, (waste oil → pretreatment degumming → methyl alcohol pre-esterification → transesterification is prepared by ester exchange reaction of the prior art
Change → separating methanol → dehydration → decolouring → distillation → C12-18Fatty acid methyl ester), it is the renewable sources of energy, turn waste into wealth, it is preferably clear
The clean energy.
For waste oil through ester exchange reaction after, generally use C therein12-18Fatty acid methyl ester is preferable.Because middle carbon fat
The carbon chain lengths of fatty acid methyl esters are moderate, and its kinematic viscosity is moderate, and condensation point is suitable for low temperature and uses close to diesel oil, 95% material
Flow is not higher than 365 degree, catches fire moderate, and flame distribution is uniform, beneficial to engine work；Flash-point is moderate, and security is good；Lubricating capacity
Good, do not wear and tear engine, extends engine life.
The above methyl alcohol is the methanol reagent more than or equal to 99.9% using methanol content.
Found through overtesting, add appropriate UV-531 to improve clearly in clean fuel oil
The stability of clean fuel oil, can prevent oil product from changing colour because absorbing ultraviolet, improve the oxidation resistance of oil product, the oxidation of oil product
Stability strengthens, and oil product is remained unchanged for a long period of time color.
The preparation method of the above clean fuel oil, comprises the following steps：
S1, under 60-90 revs/min of mixing speed, stir while to C4-12Hydrotropy table is sequentially added in fatty alcohol
Face activating agent, combustion adjuvant, methyl alcohol, sebacate, UV-531, metal deactivator, pentaerythrite
Ester, phenmethylol, biodiesel, cetane number improver, obtain mixture；Continue to stir mixture and carry out at homogeneous mixture
Reason, homogeneous speed is more than 2000 revs/min, and homogenizing time is more than 15 minutes；Then stirring and homogeneous are stopped, mixture is quiet
More than .5h is set to 0, mixed liquor is obtained；
S2, in mixed liquor add decompression one line heavy diesel fuel, while stirring and more than homogeneous 0.5h, obtain fuel oil；Homogeneous
Speed is 2000-2500 revs/min, and mixing speed is 60-90 revs/min.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention adds by methyl alcohol, one line heavy diesel fuel of decompression
Plus the multiple additives of specified quantitative, make clean fuel oil that still there is fabulous stability while methanol content is high, stand one
It is not stratified more than year, do not emulsify, it is not muddy, do not precipitate, it is nondiscolouring, homogeneous bright, and corrosivity and swellability are low, energy
Consumption and power performance are suitable with No. 0 diesel oil, and physical and chemical quality indexes reach No. 0 diesel oil national standard；Especially its flash-point and No. 0 bavin
The flash-point of oil is suitable.Due to containing substantial amounts of methyl alcohol and biodiesel in clean fuel oil of the invention, not only greatly reduce
The consumption of mineral diesel, is also effectively reduced the discharge of harmful substance, flue dust, and environmental-protecting performance is excellent, and waste gas discharge index expires
No. VI discharge standard in foot Europe.Clean fuel oil of the invention can be used alone after can also being blent with diesel oil and use, and it can be complete
Energy diesel oil substitute is applied to the fields such as internal combustion engine, Industrial Boiler and power plant.
