Problems solved by technology

The main problems are as follows: 1. Stratification problem, that is, the miscibility problem of a large proportion of methanol and gasoline; 2. Low temperature start-up problem; 3. High temperature air resistance problem; 4. Low calorific value problem; Parts corrosion problems; six, swelling problems
[0003] Patent application number 200710018605.3 discloses a new type of environmentally friendly alcohol-based petroleum gasoline. Although it solves the problems of partial delamination and corrosion, it does not fundamentally solve the problems, and most of its components are still petrochemical gasoline. The process still produces a large amount of polluting tail gas such as sulfur dioxide and carbon monoxide

[0029] (1), feed intake: first open the reactor valve, then open the corresponding connection valve between the reactor and the blending tank, finally open the valve of the blending tank and start the machine, mix 40% methanol, 2% isobutanol, 1.5% of ether, 0.5% of dodecanol, 0.05% of hexamethylenetetramine, 0.05% of T501; 0.2% of N, N'-disalicylic-1,2 propylenediamine, 0.7% of Dimethyl carbonate is put into the reaction kettle after passing through ...

Embodiment 2

[0035] First weigh the following raw materials by weight percentage:

[0036] Main combustion agent: methanol 50%, dimethyl ether 42%

[0037] Combustion enhancer: 2% isobutanol, 1% ethanol

[0038] Ignition agent: ether 3.5%

[0039] Co-solvent: dodecyl alcohol 0.5%

[0040] Preservative: Hexamethylenetetramine 0.05%

[0041] Antioxidant: T501 0.1%;

[0042] Corrosion inhibitor: N,N'-disalicylic-1,2 propylenediamine 0.2%

[0043] Dispersant: dimethyl carbonate 0.65%

[0044] Its preparation method is the same as that of Example 1, except that in the feeding step, 1% ethanol and 2% isobutanol are mixed and put into the reactor for blending reaction. The new type of environmentally friendly fuel for vehicles prepared by the above method has high dispersion efficiency, the dispersion degree can reach micron level, the appearance is crystal clear, clean as water, and the performance of fuel is stable, and it has good shock resistance, strong power and sufficient combustion....

Embodiment 3

[0046] First weigh the following raw materials by weight percentage:

[0047] Main combustion agent: methanol 65%, dimethyl ether 30%

[0048] Combustion enhancer: 1% isobutanol, 1% ethanol

[0049] Ignition agent: ether 2%

[0050] Co-solvent: dodecanol 0.43%

[0051] Preservative: Hexamethylenetetramine 0.05%

[0052] Antioxidant: T501 0.07%;

[0053] Corrosion inhibitor: N,N'-disalicylic-1,2 propylenediamine 0.2%

[0054] Dispersant: dimethyl carbonate 0.25%

[0055] Its preparation method is the same as that in Example 2.

Description

technical field [0001] The invention relates to the field of fuel, in particular to an alcohol-based gasoline fuel and a preparation method thereof. Background technique [0002] With the continuous development of social economy, the consumption of petroleum products continues to increase, natural resources are gradually exhausted and scarce, and due to the rapid development of my country's economy, the large number of social and private vehicles, the large amount of vehicle exhaust emissions have endangered people's health and life safety At the critical moment when human beings are facing energy shortage and environmental crisis, people have designed a variety of alcohol-based gasolines. Although there are many alcohol-based gasolines, there are also many problems due to immature technology. The main problems are as follows: 1. Stratification problem, that is, the miscibility problem of a large proportion of methanol and gasoline; 2. Low temperature start-up problem; 3. Hig...
