The alcohol-ether fuel is an ideal product to substitute for the diesel oil No.0.

Description

Car and boat alcohol ether fuel for diesel and gas-liquid synthesizing method thereof

Technical field

The present invention relates to a kind of fuel, especially a kind of car and boat diesel engine alcohol ether synthol.

Background technology

At present, the fuel that various transport facilitys are used, all gasoline, diesel oil in oil, to extract.Along with The development in society and economy, the fuel that needs of aspects such as industry, agricultural, communications and transportation constantly increases, but petroleum resources are more and more poorer, can't satisfy social desirability and market supply.Therefore,, seek a kind of ideal oil as substitute of diesel product, become one of important subject in the contemporary science and technology field from long term growth.Along with promoting China, national technical industry policy implements the deeply further of clean fuel plan and this fuel producing technology of development, the alternative use of synthetic liquid fuel is towards gathering materials on the spot, reduce transportation, help advancing the chemical industry fast development, being the trend of social development, also is the energy strategy decision-making of China.On July 4th, 2006, general office of National Development and Reform Committee printed and distributed the notice of dme industry development symposium meeting summary, had proposed to accelerate the requirement of fuel substitute exploitation.

Summary of the invention

The objective of the invention is to provide a kind of refiting engine that do not need, can use with existing diesel oil, the cetane value height can substitute diesel oil more than No. 0 fully, can reduce blowdown again, and technology is simple, less investment, the alcohol ether synthol of easily applying.

The present invention is achieved in that

Each material component and weight proportion that the present invention forms are:

36 parts of methyl alcohol;

30 parts of No. 0 diesel oil;

31 parts of solvent oils;

2.5 parts of additives;

0.5 part of dme.

Additive is meant totally 5 kinds of the trimethyl carbinol, tween 20, cerous nitrate, n-hexyl alcohol and nucleus magnetic resonance agent.

The ratio that additive accounts for total amount is: 1 part of the trimethyl carbinol, tween 20 are 0.8 part, 0.4 part of cerous nitrate, 0.25 part of n-hexyl alcohol, 0.05 part of nucleus magnetic resonance agent.

Gas-liquid synthesizing method of the present invention is: methyl alcohol, diesel oil, solvent oil are dropped in the retort in regular turn, heat to 45～55 ℃, stirred under 0.2kg pressure 12～18 minutes, add additive and dme again, mix and stirred 3～5 minutes, filter through essence, leave standstill, get finished product.

The performance of various raw materials in prescription and effect are as follows:

Methyl alcohol is the main fuel of this fuel, and the latent heat of vaporization, steam output are big.Contain aerobic in the methyl alcohol, required air quantity is few during burning, realizes perfect combustion easily, and combustion exhaust CO measures decline, because its vapour pressure latent heat is big, mixed air temperature needs to descend when vaporization, has improved inner cooling conditions, reduced inlet air temperature simultaneously, thereby gassing factor improves, and has improved dynamic performance.Waste gas alleviates the diluting effect of combustible gas, also has good anti-knocking property.The advantage of methyl alcohol is that tail gas has only 1/3rd of ordinary diesel oil to atmospheric exhaust emission, possesses the condition of the automobile-used bunker fuel (No. 0 diesel oil) of the preparation of being used in again.Methyl alcohol combines with the dme gas-liquid, possesses two-fold advantage, makes spout aerosolization more on the direct injection ic engine, igniting easily, increased the ability that diesel engine bears a heavy burden and goes up a slope, complementary again shortcoming separately, the adding of adding multiple additives makes it improve power function more.

Additive is made up of igniting combustion supporting agent, catalyzer and sanitas cetane number booster.Add the igniting combustion supporting agent and played the not smooth effect of methyl alcohol direct starting, have easily start, the characteristics that ignition characteristic is good, the feature that mixes.Dme is selected in igniting combustion supporting agent of the present invention for use, in order to improve the effect of car power and explosive power.Catalyzer is selected the trimethyl carbinol for use, has the calorific value of raising, increases horsepower, promotes dissolving each other of various raw materials, has solved the layering of synthol and has prevented the effect of oily group.Sanitas is selected tween 20 and cerous nitrate for use, can play the caused multiple metallic corrosion of pure fuel and suppress effect preferably, because alcohols has very high water absorbability, in preparation process, alcohol contains a spot of organic acid, also can form organic acid because of oxidation in storing and using.The existence of acidic substance like this causes the corrosion of metal parts in the fuel system, influences the life-span of engine, therefore adds sanitas and is absolutely necessary.Because the dual function of n-hexyl alcohol and nucleus magnetic resonance agent in the additive, greatly improve the cetane value of synthol, make it reach No. 0 more than the standard, can improve flash-point (remaining silent) again to reach 〉=55 ℃, reduced the whole proportion of synthetic propellant combination, also have fume-eliminating energy-saving, wear-resistant effect, make power increase under the situations such as synthetic propellant combination is overweight under steam, upward slope.

Pure ethers car and boat fuel of the present invention, the experiment of navigating through driving in a few years and compare with prior art has following remarkable advantage:

(1) do not need refiting engine, can use with, can use separately yet with existing ordinary diesel oil.Having reduced the consumption of diesel oil to greatest extent, is the desirable articles for use that substitute No. 0 diesel oil with new forms of energy.

(2) methanol content is up to 36%, and No. 0 diesel oil of fuel outward appearance and commodity is the same.

(3) cetane value is up to (seeing survey report) more than 48.4, is up to surpass No. 50.2, do not conform to lead, and do not pollute during products production, when emission by exhaust pipe waste gas than No. 0 diesel oil reduction blowdown 55%.

(4) production process need not high temperature, high pressure, and technology is simple, and is easy to operate, less investment, and abundant raw material, cost are low, and the rate of economizing gasoline height is easy to apply.

(5) ignition characteristic good, easily start, non-oxidation, few burn into thermo-efficiency height.Its performance index are near the standard (result who detects at the on-the-spot odd test of product quality supervision and testing institute proves) of No. 0 diesel oil that surpasses national regulation.

(6) has good anti-knocking property, security and stability.

Application and Development of the present invention will be brought very big economic benefit and atmospheric layer environmental protection benefit to society.
