[0002] Wood alcohol gasoline is one of the many preferred options for alternative automotive fuels.

[0003] Wood alcohol has a high octane number, and the octane number of the synthesized wood alcohol gasoline is also high, but it does not meet the national octane number standards for various gasoline brands, which affects the use effect. The present invention can produce automotive wood alcohol gasoline that meets the national standard brands. Summary of the Invention

[0004] The purpose of the present invention is to provide a gasoline synthesized from wood alcohol, naphtha, gasoline, additives, anti-corrosion and anti-gelling agents, combustion accelerators, etc., wherein the amount of wood alcohol incorporated is large, stratification does not occur during storage and use, automobile exhaust pollution can be minimized, there is no adverse effect on automobile engines, combustion effect is good, production costs can be reduced, and the gasoline for use with wood alcohol of various grades meeting national standards can be synthesized under normal temperature and pressure conditions.

[0005] The present invention is to synthesize various grades of wood alcohol gasoline for automobiles according to national standards, which is characterized in that the composition (weight %) is:

[0006] The wood alcohol described in the present invention is wood alcohol with a content of ≥99% that is filtered through a 400-mesh net.

[0007] The additive of the present invention is composed of the following components (weight %):

[0008] The anti-corrosion and anti-glue agent of the present invention is in the form of Dimethyl phthalate 10.0-80.0% Dipentene 3.0-50.0% Benzotriazole 5.0-60.0%

[0009] The combustion accelerator of the present invention is in the form of Peroxide 5.0-40.0% Toluene 8.0-60.0% Xylene 10.0-80.0%

[0010] The method for producing synthetic wood alcohol gasoline for automobiles of various brands meeting national standards is as follows, calculated by weight percentage:

[0011] Under normal temperature and pressure conditions, wood alcohol, naphtha, gasoline, additives, anti-corrosion and anti-gelling agents, and combustion accelerators are placed in respective containers, mixed evenly according to the proportion of the components, and then sealed for storage; one of the methods: under normal temperature and pressure conditions, acetone, n-butanol, methyl tert-butyl ether, S-80, and trimerized linoleic acid are mixed evenly according to the proportion of the components, and then filtered; two of the methods: under normal temperature and pressure conditions, dimethyl phthalate, dipentene, and benzotriazole are mixed evenly according to the proportion of the components, and then filtered; three of the methods: under normal temperature and pressure conditions, peroxide, toluene, and xylene are mixed evenly according to the proportion of the components, and then filtered.

[0012] The wood alcohol described in the present invention is the main combustion agent of the fuel, which generally has a higher octane number than gasoline, a large evaporation heat, a large gasification expansion coefficient, and a high heat utilization rate; naphtha and gasoline serve as ignition agents and main combustion agents; the additives mainly consist of cosolvents (acetone, n-butanol) and stabilizers (S-80, trimerized linoleic acid); the addition of methyl tert-butyl ether to the components can improve the cold start characteristics and acceleration of gasoline, promote complete combustion of fuel, reduce black smoke emitted by the engine, and achieve the goals of pollution prevention, clean energy, and a clean environment; the addition of S-80 and trimerized linoleic acid can further promote the mutual dissolution of various raw materials, and solve the problems of fuel stratification and oil clumping; the anti-corrosion and anti-gelling agent consists of a rust inhibitor (benzotriazole) and an anti-rubber swelling agent (dimethyl phthalate, dipentene); the combustion accelerator consists of peroxide, toluene, and xylene, which increases the calorific value and enhances power.

[0013] Compared with the prior art, the present invention has the following features:
