Embodiment 1

[0064] A kind of high-stability methanol gasoline, which is prepared by mixing the following raw materials in volume percentage:

[0065] National standard 90# motor gasoline 40%

[0066] Industrial Methanol 41.5%

[0067] Phase stabilizer 15%

[0068] Vapor pressure regulator 3%

[0069] Anti-corrosion anti-swelling agent 0.5%.

[0070] The 15% phase stabilizer consists of: 5% methyl tert-butyl ether, 5% ethylene glycol butyl ether, 3% n-butanol, 2% MOA-3, and the vapor pressure regulator is dimethyl carbonate , the anti-corrosion and anti-swelling agent is benzotriazole. The above are volume percentages, and the same will not be described below.

[0071] The preparation method of this embodiment is as follows: at normal temperature and pressure, first add industrial methanol in proportion to the blending tank filled with national standard 90# motor gasoline, and then add phase stabilizer, vapor pressure regulator and Anti-corrosion and anti-swelling agent, after the ad...

Embodiment 2

[0074] The raw material composition volume ratio of this embodiment is the same as that of Example 1, and the difference is that: the 15% phase stabilizer consists of: 5% methyl tert-butyl ether, 5% ethylene glycol butyl ether, 3% normal Octanol, 2%MOA-3B, the vapor pressure regulator is diisopropyl ether, and the anti-corrosion and anti-swelling agent is n-butylamine.

[0075] The preparation method of this embodiment is the same as that of Example 1.

[0076] The methanol gasoline of this embodiment has high stability, its water solubility is 2.0%, its low temperature resistance is -33°C, its saturated vapor pressure is 65kPa, its swelling rate is 0.3%, and its corrosion degree of copper sheet is less than grade I, which effectively solves the problem of existing alcohol oil fuel. outstanding issues. The methanol gasoline of this embodiment has strong power, low fuel consumption, high efficiency and cleanliness, and low preparation cost, can be directly used by motor vehicl...

Embodiment 3

[0078] A kind of high-stability methanol gasoline, which is prepared by mixing the following raw materials in volume percentage:

[0079] National standard 90# motor gasoline 62.7%

[0080] Industrial Methanol 25%

[0081] Phase stabilizer 10%

[0082] Vapor pressure regulator 2%

[0083] Anti-corrosion anti-swelling agent 0.3%.

[0084] The 10% phase stabilizer consists of: 2% methyl tert-butyl ether, 2% ethylene glycol butyl ether, 5% n-butanol, 1% MOA-3; the vapor pressure regulator is dimethyl carbonate , the anti-corrosion and anti-swelling agent is benzotriazole.

[0085] The preparation method of this embodiment is as follows: at normal temperature and pressure, first add industrial methanol in proportion to the blending tank filled with national standard 90# motor gasoline, and then add phase stabilizer, vapor pressure regulator and Anti-corrosion and anti-swelling agent, after the addition is completed, use the pump to circulate, stir for 15 minutes, and finally ...

Abstract

The invention relates to a high-stability methanol gasoline and a preparation method thereof. High stability methanol gasoline is prepared by mixing the following raw materials in volume percentage: 40%~80% of motor gasoline, 10%~50% of industrial methanol, 7%~15% of phase stabilizer, 0%~5 of vapor pressure regulator % or anti-corrosion and anti-swelling agent 0.05%~1%. The method is: under normal temperature and pressure, add industrial methanol in proportion to the blending tank containing motor gasoline; add phase stabilizer, vapor pressure regulator and anti-corrosion and anti-swelling agent in proportion; use pump to circulate, stir 10-20 minutes; after standing in the blending tank for 1-2 hours, pour into the storage tank for later use. The methanol gasoline prepared by the invention has high stability, strong power, low fuel consumption, high efficiency and cleanliness, and low preparation cost, can be directly used by motor vehicle engines, and has good industrial production prospects.

Description

technical field [0001] The invention relates to a high-stability methanol gasoline and a preparation method thereof. Background technique [0002] With the rapid development of my country's economy, the production and sales of automobiles have increased significantly. Under the strong demand for vehicle fuels, a variety of alternative fuels for motor vehicles have emerged, among which methanol gasoline is the fastest growing. Methanol has high oxygen content, large latent heat of vaporization, wide range of sources, and low pollution of combustion products. Therefore, methanol gasoline is considered to be an ideal substitute for vehicle gasoline, but in the actual production, storage and use process, methanol gasoline has encountered Water phase separation, low temperature phase separation, high temperature air resistance, swelling, corrosion and other prominent problems, for this reason, researchers have conducted a lot of research work on improving the performance of metha...
