Description
Technical field
The invention belongs to vehicle fuel technical fields, and in particular to a kind of aqueous alcohol ethers diesel fuel and its preparation
Method.
Background technique
Alcohol-ether fuel mainly includes methanol, dimethyl ether, is to be considered highly important substitute energy source for petroleum now, is also claimed
For coal-based alcohol ether fuel, the low-carbon oxygen-containing fuel mainly synthesized by coal by gasification, as widest automobile-used substitution vapour
The fuel of oil, diesel oil, not only increases comprehensive resource utilization rate, and be of great significance to reducing environmental pollution, meanwhile, by
The alcohol-ether fuel of coal conversion extremely meets the developing direction of coal conversion, coal gasification, has good economy.Currently, having had
Much the research that alcohol-ether fuel and gasoline, diesel oil are mixed with new fuel is reported.
Alcohol ether diesel oil for vehicles is formed in volume or weight than a certain proportion of alcohol ethers fuel formulations are added in diesel oil
A kind of environment friendly energy conservation fuel, however, during alcohol ether and diesel oil mix, it usually needs addition composite auxiliary solvent helps
Stable homogeneous system is formed, since alcohol ethers and diesel oil itself physicochemical property difference are larger, selects suitable cosolvent very
Key, studies have reported that adjusting the flash-point of alcohol ethers by water phase.But in the alcohol ethers diesel fuel for being added to water phase, according to
So there is a problem of stability difference, in order to improve its compatibility, also has been reported that addition includes acidic materials or the lipids such as oleic acid
The cosolvent of matter (such as ethyl acetate etc.) carries out hydrotropy, but unsatisfactory to the improvement of product stability.
And find in actual production, the substances such as methanol mixed with diesel oil can be emulsified when meeting water, it is general and
Speech, the full combustion of diesel oil can be promoted by forming Diesel Oil-methanol ternary emulsifying system, save petroleum resources, but its stability
It is not easy to control, so that oil plant is become muddy, whiten, or even generate floating material or flocculate, influences hybrid fuel appearance character, seriously
Ground even has an adverse effect to combustion chamber, pipeline, and some reasons are since impurity content is higher in the industrial production for methanol
Caused by, in general, the above problem can be improved by carrying out purifying upgrading processing to methanol, but production cost is improved simultaneously.Another party
Face, the alcohols materials such as methanol itself have stronger hydrophily, but its absorption moisture is more, poorer with the intersolubility of diesel oil, sternly
Important place can lead to oil layer, stability is poor.
China's Sulfur Content in Petroleum Products is higher at present, has aggravated the pollution level of automotive emission, has contained compared to gasoline
There is more impurity, it is easier to pollute environment, therefore deep desulfuration processing is carried out to diesel oil, it is miscellaneous that part is also removed while desulfurization
Matter.However, polycyclic aromatic hydrocarbon nitrogenous compound, the sulphur-containing substance etc. in diesel oil have certain influence to the lubricity of diesel oil, these
After devolatilization, diesel fuel lubricity is deteriorated, and causes motor car engine serious wear.
Summary of the invention
In order to solve the above technical problems, the present invention provides a kind of aqueous alcohol ethers diesel fuel, contain water, first described
In the diesel oil of the fuel such as alcohol, dimethyl ether, by the way that long-chain fatty alcohol is added, long chain fatty acids ester admixture carries out hydrotropy, lubrication, nothing
Purification process need to be carried out to the alcohol ethers class A fuel A such as methanol, can be obtained stability height, lubricity is good, diesel oil service performance is improved,
Reduce the novel environment friendly fuel of tail gas charcoal discharge amount, application value with higher.
On the one hand, the present invention provides a kind of aqueous alcohol ethers diesel fuel, and in parts by weight, the fuel includes:
Preferably, in parts by weight, the aqueous alcohol ethers diesel fuel includes:
Wherein, the auxiliary agent is the mixture of long-chain fatty alcohol and long-chain fatty acid ester, in aqueous alcohol ether of the invention
Hydrotropy, wear-resisting, synergism characteristic are played in class diesel fuel, contributes to form stable solution, increase the fuel to the packet of water
Capacitive makes the additive amount of water reach nearly 20%, while enhancing the lubricity of fuel, reduces the abrasion to engine.
Preferably, the long-chain fatty alcohol is the chain fatty alcohol with 6-18 carbon atom, such as Lauryl Alcohol, 14
Carbon alcohol, the pure and mild octadecanol of 16 carbon；The long-chain fatty acid ester is to be formed by the fatty acid with 6-18 carbon atom with alcohol
Monoesters or polyester, such as glycerol stearate monoesters, palmitinic acid fourth diester, Glyceryl Monolaurate, myristic acid glycerol list
Ester, Trivent OCG etc..Inventor has found that the mixability of the auxiliary agent is more complicated, to shape by orthonormal design of experiments
Higher at the effect of stablizing solution, that is, the ingredient mixed is more, and fuel is more stable, and as contained acids object in the auxiliary agent
Matter can destroy the stability of fuel, may be since acid and the Cucumber in diesel oil, methanol fuel, dimethyl ether fuel (can
Can be alkaline matter) it is reacted.
Preferably, the weight ratio of the long-chain fatty alcohol and long-chain fatty acid ester is 1:1-3.
Diesel oil used in the present invention is preferably national standard diesel oil, such as No. 5 derv fuels, No. 0 derv fuel ,-No. 10 vehicles
With diesel oil, in the case where the improvement of auxiliary agent helps, the addition of water, alcohol ether class A fuel A will not significantly improve the condensation point of diesel oil, especially solidifying
The higher diesel product of point.
Methanol used in the present invention is industrial methanol, can be manufactured by methods known in the art, such as can be by
The preparation such as natural gas, coal bed gas, oven gas, and denatured alcohol auxiliary agent can be wherein added, the industrial methanol needs not move through spy
Different purification process, but the content of methanol need to be in 75% or more, preferably 80-85%.Similarly, dimethyl ether used in the present invention
The industrial dimethyl ether that can be manufactured by methods known in the art, wherein the purity of dimethyl ether is 70% or more.
Without limitation, it can also be added and other commonly add in aqueous alcohol ethers diesel fuel of the invention in fuel
Add agent, such as ignition improver, antidetonation catalyst, rubber accelerator, antioxidant etc., condition is not influence the burning spy of fuel
Property.
On the other hand, the present invention also provides the preparation method of above-mentioned aqueous alcohol ethers diesel fuel, the method includes
Auxiliary agent is heated to 40-50 DEG C, is passed through in the stirring at normal temperature tank equipped with diesel oil, is added methanol, dimethyl ether, water, be sufficiently stirred
It is uniformly mixed, stands and obtain stable liquid, as aqueous alcohol ethers diesel fuel.
Technical solution of the present invention has the advantages that
In the diesel oil containing fuel such as water, methanol, dimethyl ether, by the way that long-chain fatty alcohol, long chain fatty acids is added
Ester admixture carries out hydrotropy, lubrication, without carrying out purification process to the alcohol ethers class A fuel A such as methanol, can be obtained stability height, profit
The good novel environment friendly fuel of slip improves water content, increases hybrid fuel in transport, cargo handling process to the containment of water.Together
When, added long-chain fatty alcohol, long chain fatty acids ester admixture auxiliary agent have the function of hydrotropy, lubrication, improve the resistance to of diesel oil
Mill property reduces the abrasion to engine, to attributes such as condensation point, the flash-points of fuel without damaging influence.And compared to common bavin
For oil, due to being mixed into the water and alcohol ether class A fuel A of nearly half weight, diesel oil service performance is improved, the discharge of tail gas charcoal is reduced
Amount, and character is stablized, application value with higher.
