Abstract
The invention discloses an additive which can stabilize and synergize the effects of a vehicle-used methanol-diesel. Under the condition of stirring, certain amounts of n-caprylic alcohol, n-amyl alcohol, oleic acid, naphthenic acid, Span-80 and acrylic ester are respectively driven into a reactor and stirred at a slow speed to be fully and evenly mixed; then under the condition of cooling, set amount of triethanolamine is gradually added and fully stirred for complete reaction; after cooling to room temperature, barreling and sealing, the additive of the invention is obtained. The additive of the invention can enhance the burning efficiency of the methanol-diesel and achieve the purpose of saving the diesel. The methanol-diesel made by using the additive is not only transparent and stable but has good water resistance and cold resistance and can be stored for a long term; the performance indexes of the methanol-diesel can basically meet the requirements of commercial diesels, can be randomly mixed with other diesels without the phenomena of emulsion separation and phase separation and can be conveniently used; the additive can improve the shortcoming of low flash point of the methanol diesel and make up the deficiency of low cetane value of the methanol.
Description
Technical field
The invention belongs to the methanol fuel for vehicles technical field, especially relate to a kind of stable synergistic of methanol diesel for vehicle.
Background technology
Along with the high speed development of world economy, in continuous growth, based on the deficient relatively reality of the China's oil energy, develop actively fuel oil alternative industry is the requirement of national energy security to the demand of oil in countries in the world.There is tangible gap in all parts of the country in the research and development to methanol diesel-oil now, be difficult to solve that low temperature is anti-to be separated and to meet that water is anti-to be separated and the short phenomenon of phase separation of preservation period, and the methanol diesel-oil physical and chemical index of producing do not meet the performance requriements of derv fuel oil, and economic worth is not high.
Diesel oil burns in engine, because incomplete combustion, combustion thermal efficiency fails to give full play to, and fuel is not fully utilized, and produces over-emitting black exhaust simultaneously and pollutes environment.
At present, the domestic methanol diesel-oil that uses is oyster white, because the mutual solubility of diesel oil is poor, and immiscible with additive or emulsifying agent, emulsus and phenomenon of phase separation appear easily, and short with the methanol diesel-oil quality guaranteed period that existing additive or emulsifying agent are produced, can not standing storage, poor stability, the efficiency of combustion of methanol diesel-oil can not get improving, and make methanol diesel-oil can not satisfy the requirement of derv fuel oil.
Summary of the invention
Technical problem to be solved by this invention is at above-mentioned deficiency of the prior art, provide a kind of and can reduce environmental pollution, the methanol diesel-oil steady quality of producing, the stable synergistic of methanol diesel for vehicle that the methanol diesel-oil efficiency of combustion is improved significantly is to reach the purpose of saving diesel oil.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of stable synergistic of methanol diesel for vehicle is characterized in that the raw material composition and the weight percent of this additive is:
N-Octanol 8-20% Pentyl alcohol 10-25% oleic acid 15-30% naphthenic acid 10-25%
Trolamine 2-10% sorbester p17 2-8% acrylate 3-10%.
The preferred technical solution of the present invention is: a kind of stable synergistic of methanol diesel for vehicle is characterized in that the raw material composition and the weight percent of this additive is:
N-Octanol 20% Pentyl alcohol 25% oleic acid 25% naphthenic acid 15%
Trolamine 5% sorbester p17 3% acrylate 7%.
Preparation method of the present invention is: under whipped state, squeeze into n-Octanol, Pentyl alcohol, oleic acid, naphthenic acid, Arlacel-80 and the acrylate of above-mentioned weight percent in the reactor successively, make its complete uniform mixing under stirring at a slow speed, the trolamine that under cooling conditions, progressively adds above-mentioned weight percent then, fully stir, make to react completely, be cooled to room temperature after, the barrelling sealing promptly makes stable synergistic of methanol diesel for vehicle of the present invention.
The raw material of making additive of the present invention can obtain from biomass material, nearly all belong to oxygenatedchemicals, all become effective integral part of diesel oil fuel simultaneously, thereby the efficiency of combustion of favourable raising diesel oil, improve the low shortcoming of methanol diesel-oil flash-point, and the deficiency that remedies the methyl alcohol cetane value.
The present invention compared with prior art has the following advantages: additive of the present invention can improve the efficiency of combustion of methanol diesel-oil, reach the purpose of saving diesel oil, the methanol diesel-oil made from this additive is transparent and stable not only, water-fast cold resistance is good, the energy standing storage, and can be mixed arbitrarily with diesel oil, emulsus and phenomenon of phase separation can not appear, the convenient use, this additive can improve the low shortcoming of methanol diesel-oil flash-point, remedies the deficiency of methyl alcohol cetane value; Under emulsification, dispersion, hydrotropy and the stirring action of set amount additive product of the present invention, the methanol diesel-oil product that the methyl alcohol and the diesel oil of set amount can be formed transparent and stable, after testing, the performance index of the methanol diesel-oil of production can satisfy the requirement of commercial Dissel oil substantially.
Below by embodiment technical scheme of the present invention is described in further detail.
