Description
Technical field
The present invention relates to petrochemical industry, be specifically related to a kind of methanol diesel-oil and preparation method thereof.
Background technology
Methanol diesel-oil is the fuel that diesel oil, methyl alcohol and optional additive form through strict flow process allotment according to certain volume or mass ratio.The use of methanol diesel-oil both can save petroleum resources, reduce cost, can reduce atmospheric pollution again, was a kind of novel energy of environment-protecting clean, had been subject to paying close attention to widely.
Although methanol diesel-oil has very significantly advantage with respect to traditional petrochemical industry resource, also there are various defectives in himself, and as corrodibility is high, mutual solubility is poor, flash-point is low, dynamic property is poor etc., wherein important one is exactly that the mutual solubility of methyl alcohol and diesel oil is poor.Methyl alcohol belongs to polar molecule, and the alkanes in the diesel oil becomes to belong to non-polar molecule, and according to the similar principle that mixes, methyl alcohol and diesel oil are difficult to mutually merge.Chinese patent CN101381632A discloses a kind of methanol diesel-oil, and it has added multi-component auxiliary material and additive improving the mutual solubility of methyl alcohol and diesel oil, but the raw material type that this methanol diesel-oil uses is many, complicated process of preparation, cost are higher.Chinese patent CN101955814A discloses a kind of dimethyl ether-methanol-diesel, with dme as main solubility promoter, strengthened the mutual solubility between methyl alcohol and the diesel oil, thereby improved the combustion and emission performance of integrated fuel, but the usage quantity of methyl alcohol is very little in this technical scheme, and inflammable and explosive dme addition is excessive, so the methanol diesel-oil cost of gained is high, potential safety hazard is large.Chinese patent CN102161922A discloses a kind of methanol diesel-oil, has wherein added the additive that contains ferrocene, although diesel fuel characteristics is improved, ferrocene is with high costs, causes the methanol diesel-oil holistic cost to rise.
In the existing research, be to adopt the mode of physics to increase methyl alcohol and diesel oil mutual solubility with additives such as tensio-active agent, solubility promoters mostly, the effect that obtains is very limited.
Summary of the invention
For overcoming the technological deficiencies such as existing methanol diesel-oil cost is high, mutual solubility is poor, performance is not good, the purpose of this invention is to provide a kind of methanol diesel-oil.
The preparation method who the purpose of this invention is to provide a kind of methanol diesel-oil.
Methanol diesel-oil provided by the invention comprises following raw material by weight: 100～300 parts of methyl alcohol, 400～700 parts of diesel oil, 50～200 parts of lipid acid, 20～150 parts of petroleum acids, 1～15 part of solubility promoter, 20～100 parts of aviation kerosenes, 0.1～5 part of cetane number improver and 1～10 part of zinc peroxide.
Preferably, described methanol diesel-oil comprises following raw material by weight: 150～250 parts of methyl alcohol, 450～650 parts of diesel oil, 100～150 parts of lipid acid, 50～100 parts of petroleum acids, 5～12 parts of solubility promoters, 50～80 parts of aviation kerosenes, 0.5～1.5 part of cetane number improver and 2.5～5 parts of zinc peroxides.
Wherein, described diesel oil is biofuel and/or fossil diesel fuel.
Wherein, the described diesel oil mixture that to be biofuel and fossil diesel fuel form with 1: 1～10 weight ratio.Preferably, the described diesel oil mixture that to be biofuel and fossil diesel fuel form with 1: 1～5 weight ratio.
Wherein, described biofuel is diesel-fuel blending biofuel.
Wherein, described lipid acid is non-animal grease class lipid acid, and preferably, described non-animal grease class lipid acid is one or more in palmitinic acid, oleic acid, linolic acid, the stearic acid.
Wherein, described solubility promoter is one or more in Virahol, propyl carbinol, isopropylcarbinol, n-Octanol, isooctyl alcohol, secondary octanol, the hexalin; Preferably, described solubility promoter is the mixture that is comprised of with arbitrary proportion Virahol, isopropylcarbinol and isooctyl alcohol; More preferably, described solubility promoter is by weight by Virahol: isopropylcarbinol: isooctyl alcohol=1～3: 1～5: 1～6 mixture that forms.With respect to the single-component solubility promoter, multi-component solubility promoter is better to the adsorption effect of free methanol, and especially the alcohol mixture of Virahol, isopropylcarbinol and isooctyl alcohol composition can play synergy, and is best to the adsorption effect of methyl alcohol.
Wherein, described cetane number improver is isooctyl ester nitrate.
Wherein, described aviation kerosene is preferably the 3# aviation kerosene.
Methanol diesel-oil provided by the invention has following characteristics:
(1) methanol diesel-oil system of the present invention has added zinc peroxide as catalyzer, make methyl alcohol at normal temperatures with petroleum acid and lipid acid generation esterification generating portion methyl esters, the methanol molecules of the adsorbable free existence of Ester forms common solution, the methanol molecules of dissociating in the minimizing system, the methanol molecules of also adsorbable free existence of the biofuel that similarly, adds in the system (main component is fatty acid methyl ester) forms common solution.In addition, the alcohols materials such as isooctyl alcohol as solubility promoter also can adsorb methanol molecules, the methanol molecules of dissociating in the further minimizing system.Based on this, the characteristic that recycling solubility promoter, biofuel and fossil diesel fuel are dissolved each other can make the methyl alcohol of absorption and fossil diesel fuel realize good dissolving each other.Also added aviation kerosene in the methanol diesel-oil system, it is a kind of good solvent, can promote the mutual solubility of solubility promoter, biofuel and fossil diesel fuel, thereby further improves the mutual solubility of methyl alcohol and fossil diesel fuel.
(2) in the methanol diesel-oil system of the present invention, fossil diesel fuel and biofuel have reduced condensation point owing to having adsorbed methyl alcohol (condensation point of methyl alcohol own is lower), thereby have improved diesel number, can be used as-use of 20# diesel oil.
