Description
Technical field
The present invention relates to clean energy technology field, particularly relate 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 substitute energy, has become the selection that world's Sustainable development is the most real.Methanol diesel-oil, as a kind of cheapness, clean fuel, has been subject to paying close attention to more and more widely.Methanol diesel-oil is the fuel that diesel oil, methyl alcohol and additive are allocated through certain flow process by certain volume or mass ratio.The use of methanol diesel-oil both can save petroleum resources, reduce costs, and can reduce atmospheric pollution again, be a kind of novel energy of environment-protecting clean, receive and pay close attention to widely.But methanol diesel-oil is to the swelling property of engine fuel oil system and the corrodibility to engine metal parts, and the intermiscibility of methyl alcohol and diesel oil self significantly limit application and the popularization of methanol diesel-oil.
These not enough major causes that methanol diesel-oil exists are methyl alcohol organic solvents as a kind of strong polarity, and it has corrodibility to metals such as iron, copper, aluminium.In practice, the corrodibility of methanol diesel-oil before combustion, burning neutralization burning after all have embodiment.Fuel tank to oil tank, oiling machine, pipeline, car before burning, the oil circuit of oil feeding system, pump, strainer, nozzle all have corrosion, invade bubble for a long time, and metal iron filings etc. come off and block oil supply system, cause oil supply system to be obstructed, affect fuel feeding.In combustion processes to the increased wear of piston in cylinder body and casing wall and high temperature gaseous corrosion more serious, cause the ring changed in advance on piston.There is yellow-red liquid to discharge to the corrosion of exhaust system after burning, cause exhaust system component to change in advance, and the larger corrosion phenomenon of methanol content is more serious.The swelling property of methanol diesel-oil to plastics is mainly reflected in it makes the small-particle in plastics occur swelling and come off, and for the oil supply system of plastics, comprises the plastic components in oiling machine, easily causes small particle to block oil supply system or oil leakage phenomenon.To the greasy dirt of the oil circuit inwall of oil supply system, fuel tank, inner wall of oil tank long term accumulation, electro-chemical reaction is there is under methyl alcohol corrodes for a long time, produce cleanup action, these greasy dirts are caused to come off into the forms such as small-particle, block the pump of oil supply system, strainer, nozzle etc., cause fuel feeding smooth, serious interruption fuel feeding, this is because the super property material in methyl alcohol causes with generation ironic hydroxide phenomenon producing adsorbing contaminant in these object reaction process.
These problems that methanol diesel-oil exists constrain the practical application of clean fuel oil greatly.In methanol diesel-oil, the content of methyl alcohol is larger, and these problems are more outstanding.

Biofuel has and mineral diesel analog structure, fully can dissolve each other with diesel oil, there is the many advantages such as cetane value high (60), flash-point high (being 130 DEG C), calorific value high (9500 kilocalorie) simultaneously, can directly replace diesel oil or used in combination with diesel oil, the thermo-efficiency of diesel oil can be improved, ensure the Thorough combustion of diesel oil, simultaneously, due to the biofuel not material such as sulfur-bearing, nitrogen, sulphur, nitrogen and carbon emission amount significantly can be reduced.The biofuel used in the present invention mainly discards oil plant (sewer oil) for raw material with dining table, is prepared and obtain that (sewer oil → pre-treatment is come unstuck → methyl alcohol pre-esterification → transesterification → separating methanol → dehydration → decolouring → distillation → C by transesterification reaction of the prior art
12-18fatty acid methyl ester), being the renewable energy resources, turning waste into wealth, is desirable clean energy.
For sewer oil after transesterification reaction, the general C used wherein
12-18fatty acid methyl ester is better.Because the carbon chain lengths of middle carbon fatty acid methyl esters is moderate, its kinematic viscosity is moderate, and condensation point is close to diesel oil, and be suitable for low temperature and use, 95% material flow process, not higher than 365 degree, is caught fire moderate, and flame distribution is even, is beneficial to engine operation; Flash-point is moderate, and security is good; Lubricating capacity is good, and do not wear and tear engine, extends engine life.
The above methyl alcohol is the methanol reagent using methanol content to be more than or equal to 99.9%.
Find through overtesting, add the stability that appropriate Octabenzone can improve clean fuel oil in clean fuel oil, oil product variable color because absorbing ultraviolet can being prevented, improving the resistance of oxidation of oil product, the oxidation stability of oil product strengthens, and oil product is remained unchanged for a long period of time look.
The preparation method of the above clean fuel oil, comprises the following steps:
S1, under the stirring velocity of 60-90 rev/min, to stir to C
4-12add hydrotropy tensio-active agent, ignition dope, methyl alcohol, sebate, Octabenzone, metal passivator, pentaerythritol ester, phenylcarbinol, biofuel, cetane number improver successively in fatty alcohol, obtain mixture; Continue to stir the mixture and carry out homogenization treatment to mixture, homogeneous speed is more than 2000 revs/min, and homogenizing time is more than 15 minutes; Then stop stirring and homogeneous, mixture is left standstill more than 0.5h, obtains mixed solution;
S2, in mixed solution, add decompression one line heavy gas oil, stir and more than homogeneous 0.5h simultaneously, obtain oil fuel; Homogeneous speed is 2000-2500 rev/min, and stirring velocity is 60-90 rev/min.
Compared with prior art, the invention has the beneficial effects as follows: the present invention by adding the multiple additives of specified quantitative in methyl alcohol, the line heavy gas oil that reduces pressure, clean fuel oil is made still to have fabulous stability while methanol content is high, leave standstill not stratified, not emulsification in more than 1 year, not muddy, do not precipitate, nondiscoloration, homogeneous bright, and corrodibility and swelling property low, energy consumption is suitable with No. 0 diesel oil with dynamic performance, and physical and chemical quality indexes reaches No. 0 diesel oil national standard; Especially its flash-point is suitable with No. 0 diesel-fuel flash point.Owing to containing a large amount of methyl alcohol and biofuel in clean fuel oil of the present invention, not only greatly reduce the consumption of mineral diesel, also effectively can reduce the discharge of objectionable impurities, flue dust, environmental-protecting performance is excellent, and exhaust gas emission index meets No. VI emission standard in Europe.Clean fuel oil of the present invention can be used alone also can blend rear use with diesel oil, and it can be applicable to the fields such as oil engine, Industrial Boiler and power plant by diesel oil substitute completely.
