Description
Technical Field
The invention belongs to the technical field of fuels, and particularly relates to a method for synthesizing methanol diesel.
Background
With the development of economy, the problem of insufficient petroleum backup resources is fully developed, the large consumption of petroleum fuels and the atmospheric pollution caused by the petroleum fuels are the problems to be solved urgently, the solution is to replace the traditional fuels with alternative fuels, and the development of coal fuels is an important way for solving the problems. Compared with diesel oil, the existing alternative energy source has the advantages of wide resources, easy availability, convenient transportation and acceptable cost, and meanwhile, the methanol is also a clean fuel which is accepted worldwide. From the characteristics, the methanol diesel oil at the present stage has considerable physical advantages when being used as a substitute environment-friendly fuel in the future.
There are also some alcohol-based fuels on the market at present, but these fuels cannot be stored for a long time, are not stable enough, cannot allow water to be added, even if a very small amount of water invades, can be emulsified and layered during storage, transportation and use, are not easy to ignite and are corrosive. The synthesis process of the alcohol-based fuel generally needs a large amount of additives, the inherent cost is increased, the process is complicated, the dosage of the additives is required to be particularly accurate, and the target product cannot be obtained after deviation.
Disclosure of Invention
The invention aims to provide a formula and a method for synthesizing methanol diesel, which are used for solving the problems and providing the methanol diesel and the synthesis method thereof, wherein the methanol diesel is simple in process, mild in reaction condition, high in reaction efficiency, low in energy consumption, economical and environment-friendly.
In order to achieve the above purpose, the invention adopts the following technical scheme:
the methanol diesel oil consists of the following raw materials in percentage by volume: 40-70% of light coal tar, 5-18% of methanol and the balance of auxiliary agent; the auxiliary agent consists of the following raw materials in percentage by volume: 3 to 20 percent of aviation kerosene, 2 to 20 percent of kerosene, 5 to 35 percent of ethyl acetate, 0.1 to 3 percent of ferrocene, 0.2 to 9 percent of isobutanol, 0.3 to 9 percent of propylene glycol, 0.5 to 10 percent of dimethyl carbonate and 1 to 5 percent of propylene glycol methyl ether.
The method for synthesizing the methanol diesel comprises the following steps:
step one, adding isobutanol, propylene glycol and propylene glycol methyl ether into methanol;
step two, adding the aviation kerosene and the kerosene mixed solution into the denatured methanol obtained in the step one, and uniformly stirring at 150-225 ℃ and 1-1.5 Mpa; when the temperature exceeds 150 ℃, the solubility of the denatured methanol and aviation kerosene is greatly improved, and as the flash point of an alcohol substance is usually lower than 20 ℃, the flash point of diesel oil is quite high, the safety performance of the denatured methanol and aviation kerosene is improved, and the problem of insufficient combustion liquid power is also enhanced by mixing the denatured methanol and aviation kerosene, but when the temperature exceeds 150 ℃, the oleyl alcohol mixture does not have flame retardant components and is extremely easy to ignite; reaching the limit at 225 ℃, the oleyl alcohol mixed solution has surface film-forming flame-retardant components and is not easy to ignite; no significant change at temperatures exceeding 225 ℃; when the pressure exceeds 1Mpa, the solubility of the denatured methanol and aviation kerosene is greatly improved, when the temperature is 150 ℃ and the pressure exceeds 1MP, the vapor pressure of the methanol is 1385KPa, the impurities in the oleyl alcohol mixed solution are gradually reduced, the purity is slowly improved, and the corrosion prevention technology is in a half-solution state; reaching the limit when reaching 1.5Mpa, when the temperature is 225 ℃ and the pressure is 1.5MPa, the vapor pressure of the methanol is 4036KPa, the oleyl alcohol mixed solution has no obvious impurities, the purity reaches the standard purity of the experiment, and the anti-corrosion technology is completely solved.
Step three, adding ethyl acetate and dimethyl carbonate into the light coal tar;
and step four, mixing the products obtained in the step two and the step three, adding ferrocene, and uniformly stirring at 50-90 ℃ and 1-1.5 Mpa. At 50-90 ℃, the solubility is better and the mutual dissolution is faster, and the solution can not be separated into segregation after cooling, and the aldehyde acid can be effectively inhibited, so that the problem of colloid dispersion can be solved; the solubility is better and the mutual dissolution speed is faster when the pressure is 1-1.5Mpa, the solution is not separated into segregation after being cooled, and the condition that the oleyl alcohol mixed solution is not denatured again is ensured.
In order to further realize the invention, the first step and the third step are carried out at normal temperature and pressure.
In order to further realize the invention, the stirring rotation speed in the second step and the fourth step is 30-60r/min. Too high a speed may emulsify the solution, producing a negative effect.
Compared with the prior art, the invention has the beneficial effects that:
the methanol has low cost, high octane number, wide ignition limit, and oxygen content of more than 50 percent, and is fully combusted, thus being a clean fuel accepted worldwide. However, methanol has strong toxicity to human body, low heat value, poor antiknock property, low self-ignition point, low flash point, insolubility in oil and certain corrosiveness to nonferrous metals and rubber products. But the reserves of coal mines in China are large, so that the alcohol resources are very rich.
The diesel oil has the advantages of high heat value, high flash point, no toxicity and no corrosion.
Before the additive is added, methanol cannot be mutually dissolved with oil, after the additive is added, the methanol generates freeness, is mutually dissolved with kerosene, has polarity and strong hydrophilicity, and can be infinitely dissolved in water; diesel belongs to petroleum fuel and has hydrophobicity. When methanol is denatured, the hydrophilicity of the methanol is reduced, and the combination of carboxylic acid groups and hydroxyl groups can generate condensation reaction, wherein the reaction principle is that electron cloud on carboxyl carbon is biased to carbon-based oxygen and positively charged, and the nucleophilic attack of alcohol oxygen to carbon can be initiated to obtain ester. Amphiphilic molecules are adopted to form a micelle with solubilizing capability on methanol in diesel oil, and mutual dissolution is realized through the solubilizing effect of the micelle. Thereby greatly improving the solubility with the oil substances. As the content of other substances in methanol increases, the solubility with oil substances increases.
From the cost problem, among common solvents, the lowest price of methanol and the highest price of propylene glycol methyl ether become the primary problems that the cost becomes higher along with the increase of the carbon content and the solubility of methanol and oil substances is improved on the premise of reducing the cost as much as possible.
Aviation kerosene is often used as an additive in diesel oil as a fuel to reduce the oil-producing congealing point, but is miscible with denatured methanol in step two in order to increase the flash point of alcohol substances. Alcohol flash points are generally below 20 ℃, the danger is high, and diesel flash points are above 60 ℃, so that the diesel is safer. On the premise of realizing mutual dissolution of methanol and diesel, the flash point of the diesel cannot be reduced, and the danger is increased. The main processing mode of the current diesel oil is that the light coal tar is hydrogenated, the sulfur content and the nitrogen oxide content of the light coal tar are reduced to reach the national VI emission standard, and the sulfur content and the nitrogen oxide content can be reduced by adding methanol into the light coal tar in a phase-changing way, but the safety and the combustibility of the light coal tar can not be reduced while the emission requirement is met, so that the combustibility of the light coal tar is improved in the step 3, and the final step is needed to be completed. This order cannot be disturbed, otherwise mutual dissolution cannot be completed.
The method has the advantages of cheap and easily obtained raw materials, low cost, simple process, mild reaction conditions, low energy consumption, no post-treatment, environment friendliness, high yield of the product up to 99.9%, high yield and good quality.
