Embodiment 1

[0011] Embodiment 1: get 15 parts of methanol, 83 parts of gasoline for subsequent use. First, add the following raw materials in the reaction kettle according to the weight ratio: 0.25% polyvalent isoamyl alcohol and 0.25% monohydric fatty alcohol as a solubilizer, 0.1% C 9-12 Alkanes, 0.1% refined coal tar and 0.2% anhydrous hydrazine, antioxidant 0.05% surfactant phosphoric acid, 0.1% amide, 0.1% dimethoxy and 0.1% alkanoic acid, metal corrosion inhibitor 0.1 % benzotriazole, 0.1% organic amine and 0.2% passivator, rubber swelling inhibitor 0.1% ferrocene, 0.05% organic amine, 0.1% preservative, 0.1% ethyl acetate, Additives are generated by uniform mixing. Then add 15 parts, that is, 15% methanol and additives in the reaction kettle according to the weight ratio to mix, so as to generate modified methanol. Finally, 83% gasoline is mixed with modified methanol to produce finished methanol gasoline.

Embodiment 2

[0012] Example 2: Take 20 parts of methanol and 77.5 parts of gasoline for later use, and add the following raw materials in the reaction kettle according to the weight ratio: 0.25% polyvalent isoamyl alcohol and 0.25% monohydric fatty alcohol as a solubilizer, and 0.1% energy-enhancing and consumption-reducing agent C 9-12 Alkanes, 0.2% refined coal tar and 0.2% anhydrous hydrazine, antioxidant 0.1% surfactant phosphoric acid, 0.1% amides, 0.1% dimethoxy and 0.1% alkanoic acid, metal corrosion inhibitor 0.2% benzotriazole, 0.1% organic amine and 0.2% passivator, rubber swelling inhibitor 0.2% ferrocene, 0.1% organic amine, 0.1% preservative, 0.2% ethyl acetate The additive is formed by uniform mixing; then 20 parts of methanol is added to the reaction kettle according to the weight ratio and mixed with the additive to produce modified methanol; finally, 77.5 parts of gasoline and modified methanol are mixed to produce the finished product modified methanol gasoline.

Embodiment 3

[0013] Embodiment 3: get 30 parts of methanol and 67 parts of gasoline for subsequent use. First, add the following raw materials in the reaction kettle according to the weight ratio: 0.3% polyvalent isoamyl alcohol and 0.3% monohydric fatty alcohol as a solubilizer, 0.2% C 9-12 Alkanes, 0.3% refined coal tar and 0.4% anhydrous hydrazine, antioxidant 0.1% surfactant phosphoric acid, 0.1% amides, 0.1% dimethoxy and 0.1% alkanoic acid, metal corrosion inhibitor 0.2% benzotriazole, 0.25% organic amine and 0.1% passivator, rubber swelling inhibitor 0.2% ferrocene, 0.15% organic amine, 0.1% preservative, 0.1% ethyl acetate Mix evenly to form additives; then add 30 parts, that is, 30% methanol and additives in the reaction kettle according to the weight ratio, and mix with additives to generate modified methanol; finally, mix 67% gasoline with modified methanol to generate finished methanol gasoline.

Abstract

The invention discloses a methanol gasoline and a preparation method thereof, relating to the field of new energy. The methanol gasoline comprises 15-30wt% of methanol, 67-83wt% of gasoline and 2-3wt% of additive. The preparation method comprises the following steps: pouring solubilizer, energy increasing and consumption reducing agent, anti-oxidant, metal corrosion inhibitor, rubber swelling inhibitor into a reaction vessel according to a required proportion with stirring, mixing uniformly to obtain an additive; mixing the additive with methanol according to a required proportion to obtain modified methanol; and mixing the modified methanol with gasoline according to a required proportion to obtain the methanol gasoline. The methanol gasoline disclosed in the invention has the advantagesof simple preparation and good performance, can be used mixed with a national standard gasoline in any proportion with similar energy consumption with the national standard gasoline and emission indexes that conforms to requirements of environmental protection, and can be widely used for various petrol-engined motor vehicles, such as car, carriage, fork truck, power-assisted vehicle, farm vehicle, motorcycle, load wagon and forklift.

Description

technical field [0001] The invention relates to a methanol gasoline and a blending method. Background technique [0002] The world is currently facing two major problems, one is the oil energy crisis, and the other is environmental pollution. my country's energy structure is "more coal, less oil and less gas". Since 1993, it has become a net importer of oil. In the past five years, the average annual increase in oil demand has exceeded 7%. By 2009, the national oil consumption has exceeded 400 million tons. The degree of dependence on foreign countries exceeds 54%, and China is becoming one of the major oil consumption countries in the world. More than 60% of my country's oil consumption is used for motor vehicles. How to find new alternative energy sources for vehicles has become a national strategy. The National Development and Reform Commission promulgated the "Special Report on the Development of my country's Alcohol Ether Fuel and Alcohol Ether Clean Vehicles" in 2007,...
