The preparation method of the methanol diesel oil is characterized by including (1) mixing methanol and cosolvent according to a contain volume ratio, stirring uniformly to obtain denatured methanol; and (2) adding the denatured methyl alcohol obtained in the step (1) into diesel oil according to a certain volume ratio, and stirring uniformly to obtain the methanol diesel oil. The methanol diesel oil prepared is good in stability and high in lubricity, physicochemical indexes of the methanol diesel oil meet national standards for the fuel oil, materials for the methanol diesel oil are easy to obtain, and the preparation method is simple.
Description
Technical field
The present invention relates to a kind of methanol diesel-oil and preparation method thereof, belong to the oil product manufacture field.
Background technology
Methanol fuel is a kind of New-type fuel, showing larger advantage aspect performance and the practical application thereof, its boiling point is lower than diesel oil, and gas mixture forms comparatively fast and be more even, the methyl alcohol oxygen level is high simultaneously, its inflammability limit is wide than diesel oil, so its combustionvelocity is fast, is conducive to perfect combustion, and reduce and discharge fume, there are some researches show, the carbon granules concentration during the methanol diesel-oil burning is very low, is smokeless basically; And methyl alcohol vaporizing latent heat is larger, when forming gas mixture, can reduce inlet air temperature, thereby improves gassing factor, can improve to a certain extent the burning of engine, improves thermo-efficiency, also can suppress NO
XFormation with soot.Therefore, methyl alcohol has obtained abundant attention both domestic and external as vehicle fuel.
Methanol diesel-oil generally is Water in Oil emulsion, be that methyl alcohol is disperse phase, diesel oil is external phase, methyl alcohol is dispersed in the diesel oil with pearl, owing to containing hydroxyl in the methanol molecules, exists interfacial tension at the interface of methyl alcohol and diesel oil, and the surface tension gap of diesel oil and methyl alcohol is larger, so methanol diesel-oil is a kind of thermodynamic unstable system, methyl alcohol can not stable dispersion, easily assembles and separates.For this reason, stable methanol diesel-oil be prepared, suitable tensio-active agent must be added as solubility promoter.
Summary of the invention
The present invention aims to provide a kind of preparation method of methanol diesel-oil, and its methanol diesel-oil that makes has good stability, oilness is high, and raw material is easy to get, the simple advantage of method, and its physical and chemical index all meets the fuel oil national standard.
The preparation method of a kind of methanol diesel-oil of the present invention comprises.
(1) according to certain volume ratio, methyl alcohol is mixed with solubility promoter, get denatured methyl alcohol after stirring.
(2) according to certain volume ratio, the denatured methyl alcohol of step (1) gained is blended in the diesel oil, stir and all namely get afterwards methanol diesel-oil.
Preferably, the volume ratio of the methyl alcohol described in the step (1) and solubility promoter is 1:0.5-1.
Preferred, the volume ratio of the denatured methyl alcohol described in the step (2) and diesel oil is 1:3-5.
Further preferably, the solubility promoter described in the step (1) is oleic acid.
The methanol diesel-oil of the present invention preparation has good stability, oilness is high, and raw material is easy to get, the simple advantage of method, and its physical and chemical index all meets the fuel oil national standard.
Embodiment
Embodiment one.
(1) get 20mL methyl alcohol, 15mL oleic acid mix and stir after namely get denatured methyl alcohol, for subsequent use.
(2) get 80mL0# diesel oil, the prepared denatured methyl alcohol of 20mL step (1) mixes and stirs, and namely gets methanol diesel-oil.
Embodiment two.
(1) get 20mL methyl alcohol, 10mL oleic acid mix and stir after namely get denatured methyl alcohol, for subsequent use.
(2) get 60mL0# diesel oil, the prepared denatured methyl alcohol of 20mL step (1) mixes and stirs, and namely gets methanol diesel-oil.
Embodiment three.
(1) get 20mL methyl alcohol, 20mL oleic acid mix and stir after namely get denatured methyl alcohol, for subsequent use.
(2) get 100mL0# diesel oil, the prepared denatured methyl alcohol of 20mL step (1) mixes and stirs, and namely gets methanol diesel-oil.
Embodiment four.
The physicochemical property test of methanol diesel-oil.
Above-described embodiment 1 prepared sample is carried out the mensuration of cetane value (Q/FSHFY), calorific value (GB/T384-1981) close flash point (GB/T267-1988), condensation point (GB/T510-1991) viscosity (GB/T265-1988), density (GB/ T1884-2000), colloid mass concentration (GB/T509-1988) and thermostability etc., the results are shown in shown in the following table.
Can find out by upper table, because the mixing of methyl alcohol, diesel-fuel cetane number decreases, but institute joins the methanol diesel-oil cetane value and meets diesel oil standard; The calorific value of methanol diesel-oil is than the height of pure diesel oil, and its calorific value increases with the increase of methyl alcohol; And equal low than pure diesel oil of its flash-point and viscosity, the volatility that flash-point reduces the explanation methanol diesel-oil increases to some extent, and the oilness that viscosity reduces the explanation methanol diesel-oil increases to some extent; The density of methanol diesel-oil is less than the density of pure diesel oil, and reason is that the adding of methyl alcohol increases the density of methanol diesel-oil.Though the corrosion level of methanol diesel-oil is slightly stronger than pure diesel oil, but still meet corrodibility standard (corrodibility 1 grade, 2 grades qualified), state this, methanol diesel-oil can not cause corrosion to diesel engine and member thereof, can normally use; The good thermal stability of methanol diesel-oil.Simultaneously, because the adding of methyl alcohol, the H of generation, O and OH free radical have activated diesel combustion process greatly, and the colloid that deposits is converted into CO and the H that is conducive to burn
2, make its burning more abundant.
