Abstract
The invention provides a methanol coal-based diesel oil and its production process. The methanol coal-based diesel oil comprises the following components by volume part: 20-80 of modified methanol and 20-80 of coal-based diesel oil. The process consists of the steps of: adding the modified methanol into a reaction kettle at room temperature, adding the coal-based diesel oil under a stirring condition of a rotation speed of 270-330R/M, controlling the adding time at 5-15 minutes, then, conducting further stirring for 30 minutes at a temperature of 45-55DEG C, and carrying out cooling to room temperature, thus obtaining the methanol coal-based diesel oil. The process is simple and has a low cost. The obtained methanol coal-based diesel oil has a cetane number up to 45. And after use of the methanol coal-based diesel oil, the content of harmful gases in the tail gas is greatly reduced, thus being conducive to environmental protection.
Description
technical field:
The invention provides a kind of novel diesel and production technique thereof, particularly relate to the coal-based diesel oil of a kind of methyl alcohol and production technique thereof.
background technology:
Chinese patent CN102229820 discloses a kind of denatured methyl alcohol diesel oil, in methyl alcohol, adds denaturing agent to make denatured methyl alcohol, then becomes denatured methyl alcohol diesel oil with in ordinary diesel oil preparation.Wherein, the raw material of denatured methyl alcohol is methyl alcohol, ethylene glycol monomethyl ether, unsaturated fatty acids, polymethoxy methylal, methyl propionate, encircles 11 kinds of starting material such as alcohol nitric ether.Because ordinary diesel oil cetane value is low, lower with cetane value after methyl alcohol mixture, therefore must add hexalin nitric ether in denatured methyl alcohol, to improve cetane value, but hexalin nitric ether belongs to hazardous chemical, is unfavorable for storage and the use of product.Meanwhile, also because having added hexalin nitric ether, nitric oxide production content in its exhaust emissions is increased, be unfavorable for environment protection.The coal-based diesel cetane-number in another aspect can reach 70, can reach more than 42 cetane value as after dissolving with methyl alcohol, and still, the compatibility extreme difference of coal-based diesel oil and methyl alcohol, therefore can not directly mix use.
summary of the invention:
The object of the invention is to overcome above-mentioned shortcoming, provide a kind of cetane value can reach 45, and in the rear tail gas of burning, obnoxious flavour content is low, be conducive to environment protection, and production technique is simple, the coal-based diesel oil of methyl alcohol and production technique thereof that cost is low.
The coal-based diesel oil of methyl alcohol of the present invention is made up of modified methanol and coal-based diesel oil, and its a mixing ratio by volume part meter is:
Modified methanol 20～80,
Coal-based diesel oil 20～80.
The production technique of the coal-based diesel oil of methyl alcohol of the present invention is: in room temperature downhill reaction still, add modified methanol, under the agitation condition of 300 ± 30 revs/min of rotating speeds, add coal-based diesel oil, joining day is controlled at 5～15 minutes, then, at the temperature of 50 ± 5 DEG C, continue to stir 30 minutes, be cooled to after room temperature to obtain the coal-based diesel oil of methyl alcohol.
Wherein, the proportioning of modified methanol component by volume part meter be:
Methyl alcohol 20～60,
Ethylene glycol monomethyl ether 5.0～10.0,
Liquid C12-C18 lipid acid 19.8～44.8,
C4-C12 saturated alcohol 14.0～20.0,
Methyl tertiary butyl ether 1.0～5.0,
Ferrocene 0.028,
Benzotriazole 0.002,
Laurostearic acid propyl carbinol ester 0.07,
Thanomin 0.10.
Wherein, topmost properties-correcting agent is C12-C18 lipid acid and C4-C12 saturated alcohol, and its effect is that this polar molecule of methyl alcohol can be dissolved each other with nonpolar coal-based diesel oil; Adding of ethylene glycol monomethyl ether is to increase the compression ignite of product of the present invention and improve the stability while starting with idling; The effect of methyl tertiary butyl ether is to increase product stability, not stratified after standing storage; Ferrocene can improve power as ignition dope; Benzotriazole is as inhibiter; The existence of laurostearic acid propyl carbinol ester can increase the lubricated of inboard wall of cylinder block, and forms thin film protection cylinder body; Thanomin can be suitably in and acidity in lipid acid, be beneficial to the protection of engine.
The production technique of modified methanol is:
(1) in container, add ferrocene and methyl tertiary butyl ether, under room temperature, stir and make whole dissolvings, then add laurostearic acid propyl carbinol ester, after being uniformly mixed, obtain solution A for subsequent use.
(2) benzotriazole is dissolved in ethylene glycol monomethyl ether to such an extent that solution B is for subsequent use in container.
(3) in reactor, add methyl alcohol, C12-C18 lipid acid and C
4-C
12saturated alcohol, adds thanomin under stirring under room temperature, continues to stir after 10 minutes, add solution A and solution B, then continuation stirring obtains the transparent modified methyl alcohol of glassy yellow for 10 minutes.
The advantage of the coal-based diesel oil of methyl alcohol of the present invention and production technique thereof is that the diesel oil that one, product of the present invention relate to is coal-based diesel oil, has broken away from and has relied on the present situation that oil is raw material completely.They are two years old; use the obnoxious flavour in exhaust emissions after product of the present invention greatly to reduce; detect data and show when no matter the nuisances such as CO, HC and NO are low idling or high idle speed all to reduce by 36%～59%, smoke intensity while freely acceleration (Rb) reduces by 41.77%, is conducive to environment protection.Its three, the cetane value of product of the present invention can reach 45, is greater than common 0# diesel oil.Its four, the coal-based diesel-fuel price of modified methanol is well below ordinary diesel oil, its use cost can reduce by 20%; As used on the plateau more than height above sea level 3000M, its use cost can reduce by 30-40%.Its five, production technique is simple, required starting material are easy to get, and do not need the severe condition such as High Temperature High Pressure, production cost is also low, is beneficial to popularization.
