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 present invention provides a kind of novel diesel and production technique thereof, particularly relates to 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, promptly in methyl alcohol, adds denaturing agent and makes denatured methyl alcohol, becomes denatured methyl alcohol diesel oil again with in the 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, ring 11 kinds of starting material such as pure nitric ether.Because the ordinary diesel oil cetane value is low, lower with the methyl alcohol back cetane value that is mixed, so must in denatured methyl alcohol, add the hexalin nitric ether, with the raising cetane value, but the hexalin nitric ether belongs to hazardous chemical, is unfavorable for the storage and the use of product.Simultaneously,, make nitric oxide production content increase in its exhaust emissions, be unfavorable for environment protection also because of having added the hexalin nitric ether.The coal-based diesel cetane-number in aspect can reach 70 in addition, can reach the cetane value more than 42 as after dissolving with methyl alcohol, and still, the compatibility extreme difference of coal-based diesel oil and methyl alcohol is so can not directly mix use.
Summary of the invention:
The objective of the invention is to overcome above-mentioned shortcoming, provide a kind of cetane value can reach 45, and obnoxious flavour content is low in the tail gas of burning back, help environment protection, and production technique is simple, coal-based diesel oil of the methyl alcohol that cost is low and production technique thereof.
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 cooperation 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; Agitation condition in 300 ± 30 rev/mins of rotating speeds adds coal-based diesel oil down; Joining day was controlled at 5～15 minutes; Then, under 50 ± 5 ℃ temperature, continue to stir 30 minutes, be cooled to after the room temperature 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,
MTBE 1.0～5.0,
Ferrocene 0.028,
Benzotriazole 0.002,
Laurostearic acid propyl carbinol 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; The adding of ethylene glycol monomethyl ether is the stability when increasing the compression ignite property of product of the present invention with raising startup and idling; The effect of MTBE is to increase product stability, and is not stratified after the 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 lipid acid in acidity, be beneficial to the protection of mover.
The production technique of modified methanol is:
(1) in container, add ferrocene and MTBE, under room temperature, stir and make whole dissolvings, add laurostearic acid propyl carbinol ester again, it is subsequent use to get solution A after mixing.
(2) in container, be dissolved in the ethylene glycol monomethyl ether benzotriazole to such an extent that solution B is subsequent use.
(3) in reaction kettle, add methyl alcohol, C12-C18 lipid acid and C
4-C
12Saturated alcohol stirs adding thanomin down under the room temperature, continue to stir after 10 minutes, adds solution A and solution B, continues stirring again and obtains the transparent modified methyl alcohol of glassy yellow in 10 minutes.
The advantage of coal-based diesel oil of methyl alcohol of the present invention and production technique thereof is that the diesel oil that one of which, 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 a raw material fully.They are two years old; Use that the obnoxious flavour in the exhaust emissions reduces greatly behind the product of the present invention; Detect data and show noxiouss such as CO, HC and NO all reduce by 36%～59% when no matter being low idling or high idle speed, and smoke intensity when freely quickening (Rb) reduces by 41.77%, helps environment protection.Its three, the cetane value of product of the present invention can reach 45, 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 on the plateau more than the height above sea level 3000M, using, 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 severe condition such as HTHP, production cost is also low, is beneficial to popularization.
