[0043] 1. Mix toluene 10kg, xylene 25kg, carbon 5(C 5 h 12 )5kg and carbon 7(C 7 h 16 ) 3kg into the container.

[0044] 2. Add 1.5kg of antifreeze, 0.65kg of anti-oxidant and anti-glue agent, 0.20kg of metal deactivator, 0.03kg of detergent and dispersant, 1.5kg of preservative, and 3kg of emulsifier. Mix well by circulating with the pump.

[0045] 3. Add 30kg of isobutanol, 14kg of isopropanol, 2.8kg of isoamyl alcohol, and 4kg of ethanol, and circulate with a pump until the mixture is uniform.

[0046] In addition to achieving the functions of combustion-supporting, solvent-assisted, fuel-saving, low-temperature resistance, volatilization prevention, power increase, anti-corrosion and gum removal, steam pressure adjustment, and product stability, this method can also increase the octane number of the product, and is suitable for high The purpose product of m...

Embodiment 2

[0047] Embodiment two, a kind of methanol gasoline additive, its preparation method and steps are as follows:

[0048] 1. Mix toluene 23kg, xylene 4kg, carbon 5(C 5 h 12 ) 3kg into the container.

[0049] 2. Add 2.0kg of antifreeze, 1.5kg of preservative, 2.4kg of emulsifier, 0.68kg of antioxidant and anti-glue agent, 0.2kg of metal deactivator, and 0.02kg of detergent and dispersant. Mix well by circulating with the pump.

[0050] 3. Add 29kg of isobutanol, 20kg of isopropanol, 12kg of isoamyl alcohol, and 2.5kg of ethanol, and circulate with a pump until it is evenly mixed.

[0051] Due to the high content of toluene and low content of xylene, this method is suitable for the functions of combustion-supporting, solvent-assisted, fuel-saving, low-temperature resistance, volatilization prevention, power increase, anti-corrosion and gum removal, steam pressure adjustment, and product stability. Gasoline-based target product

Embodiment 3

[0052] Embodiment three, a kind of methanol gasoline additive, its preparation method and steps are as follows:

[0053] 1. Mix toluene 10kg, xylene 25kg, carbon 5(C 5 h 12 )5kg and carbon 7(C 7 h 16 ) 3kg into the container.

[0054] 2. Add 0.68kg of antioxidant and anti-adhesive agent, 0.20kg of metal deactivator, 0.03kg of detergent and dispersant, 1.5kg of preservative, and 4kg of emulsifier. Mix well by circulating with the pump.

[0055] 3. Add 30kg of isobutanol, 14kg of isopropanol, 2.8kg of isoamyl alcohol, and 3.8kg of ethanol, and circulate with a pump until the mixture is evenly mixed.

[0056] In addition to achieving the functions of combustion-supporting, solvent-assisted, fuel-saving, volatilization-preventing, power-increasing, anti-corrosion, colloid removal, vapor pressure adjustment, and product stability, this method can also increase the octane number of the product, because no antifreeze is added. , suitable for high methanol fuel in summer when th...

Abstract

The invention relates to a methanol gasoline additive and a methanol gasoline containing the same. The methanol gasoline additive comprises the following components in parts by mass: 4-32% of toluene, 4-42% of dimethylbenzene, 0.5-10% of C5H12 and C7H16, 3-43% of isobutanol, 4-33% of isopropanol, 0.8-15% of isoamyl alcohol, 1-8% of ethanol, 1-6% of antifreezing agent, 0.2-3% of antioxygen antigum inhibitor, 0.05-0.6% of metal passivator, 0.008-0.06% of detergent dispersant, 1-6% of preservative and 2-8% of emulsifier. The methanol gasoline is prepared by the following steps: uniformly mixing gasoline, naphtha, petroleum ether, 120# solvent oil, light hydrocarbon, methanol fuel and the methanol gasoline additive, and filtering through a modified attapulgite adsorption stabilizer. The methanol gasoline produced from the methanol gasoline additive is especially suitable for high altitude anoxia regions. The methanol gasoline has the advantages of quick cycling start, stable idle speed, low harmful substance emission during combustion, favorable dynamic performance in high altitude anoxia regions, high corrosion resistance, and no stratification at low temperature, and does not generate air resistance.

Description

technical field [0001] The invention belongs to the field of fuel chemical industry, in particular to a methanol gasoline additive and methanol gasoline containing the additive. Background technique [0002] The world today is facing two major problems: one is the oil energy crisis. The world's oil reserves are limited, and with economic development, oil consumption is increasing year by year. The second is environmental pollution. The number of automobiles in our country is increasing rapidly. When petroleum products are used as fuel, the carbon oxides, hydrocarbons, nitrogen oxides, sulfur oxides, and various carcinogens contained in the exhaust gas of automobiles seriously threaten people. health. In addition, the carbon dioxide emitted by automobiles leads to the destruction of the ozone layer and the increase of the global warming effect, which has caused serious deterioration of the air quality of the living environment. Therefore, actively seeking and developing c...
