Description

A kind of Vehicular methanol petrol

Technical field

The present invention relates to a kind of Vehicular methanol petrol.

Background technology

The twentieth century later stage, be subjected to the influence of international petroleum price increase and petroleum resources short supply, carried out a large amount of and extensive experimental for methanol gasoline and carbinol gasoline fuel automobile both at home and abroad, solution from basic basic theory to actual application problem and automobile related system structure Design are transformed, that all carries out is very deep, for the development of methanol gasoline and additive and carbinol gasoline fuel automobile is had laid a good foundation.The supply of national gasoline fuel with low-ratio methanol such as Japan, the U.S. and West Europe is very general at present.The M15 high-cleaness methanol gasoline has been released in domestic on probation and research work since the methanol fuel 1980s, carries out demonstration in areas such as Shanxi, Henan and promotes.And at the methanol gasoline of 15%-85% and additive thereof owing to be subjected to the restriction of methyl alcohol physicochemical property, have that the material intermiscibility is poor, power descends, meet technical barriers such as water stratification, cold start-up difficulty, hindered its industrialization and commercialization process.

Summary of the invention:

The technical problem to be solved in the present invention be Gonna breakthrough generally acknowledge in the world when methanol content above 15% the time, the global problem that must adjust and optimize prime the fuel system and engine just, solve corrodibility, swelling property, cold start-up difficulty that methanol content ran at 15%～85% o'clock effectively, degradation technical barrier under hot gas resistance, chance moisture one-tenth, the power.

The present invention is prepared by volume and need be become by following material:

White gasoline or solvent oil, petroleum naphtha, polymerization edible vegetable oil 5%～85%; Methyl alcohol 5%～85%; Additive 1%～10%.

Wherein, additive is formed by following material blending, and each material shared volume ratio in methanol gasoline is as follows:

Methyl tertiary butyl ether 3%～5%; Methylal(dimethoxymethane) 1%～5%, acetone 1%～4%, the trimethyl carbinol 1%～1.2%, fatty acid amine 1%～3%, cerous nitrate 0.5%～1.5%, ether 1%～2%.

Compound method of the present invention is as follows:

Methyl alcohol, white gasoline (or solvent oil, petroleum naphtha, polymerization edible vegetable oil), additive are injected the one-level mixing tank simultaneously by the different directions convection current,, all pump into the secondary mixing tank again and promptly prepare and finish when each ingredients substance after all filling is finished in proportion.

The present invention is broken and solved that methanol content can not surpass 15% worldwide technological puzzle in the carbinol gasoline fuel, have following useful effect:

1, motor car engine is not proposed new requirement, have stable versatility and substituting;

2, can solve corrosion and the swelling problem of automobile in using;

3, do not exist during automobile uses because of methyl alcohol or additive and produce wearing and tearing;

4, can mix use with other alcohols motor spirit arbitrary proportion of ethanol vapor wet goods, also can directly mix use with mark gasoline arbitrary proportion with common;

5, need not service station's facility, equipment and environmental reconstruction;

6, production scene and service station environment are nontoxic;

7, not stratified, the good stability (inductive phase, min was greater than 1100) of product in suitability for industrialized production, accumulating and the vehicle use;

8, the actual effect of using is better than with the common GB gasoline of label;

9, under plateau, cold, hot environment, vehicle uses does not have the difficult problem of startup;

10, in the vehicle use, tail gas does not detect methyl alcohol, formaldehyde emissions;

11, no tangible power waste in the actual use of vehicle;

12, have good water-absorbent, need not to clear up the ponding in the fuel tank during vehicle uses;

13, with the common GB gasoline of label compare, in exhaust emission, the CO quantity discharged reduces by 83%～85%, and the HC quantity discharged reduces by 20%～30%; N and O compound quantity discharged reduce by 20%～30%;

14, its overall performance meets or exceeds the standard of GB 90#, 93#, 97# white gasoline; 15, do not have other derived materials in the production process and produce, noresidue material in service station's produces.

Embodiment:

Below in conjunction with example embodiments of the present invention are further described.

Embodiment 1: this methanol gasoline, it is become by the mixed raw material of certain volume ratio: white gasoline (or solvent oil, petroleum naphtha, polymerization edible vegetable oil) 82%, methyl alcohol 15%, additive 3% (composition of additive is because of the difference in season, feed of base oil different and adjust to some extent change)

Embodiment 2, this methanol gasoline, it is the mixed raw material one-tenth by following volume ratio; White gasoline (or solvent oil, petroleum naphtha, polymerization edible vegetable oil) 64%, methyl alcohol 30%, additive 6%.

Embodiment 3, this methanol gasoline, it is the mixed raw material one-tenth by following volume ratio; White gasoline (or solvent oil, petroleum naphtha, polymerization edible vegetable oil) 53%, methyl alcohol 40%, additive 7%.

Embodiment 4, this methanol gasoline, it is the mixed raw material one-tenth by following volume ratio; White gasoline (or solvent oil, petroleum naphtha, edible vegetable oil) 45%, methyl alcohol 45%, additive 10%.

The compound method of these methanol gasolines, white gasoline (or solvent oil, petroleum naphtha, edible vegetable oil), methyl alcohol and additive are injected the one-level mixing tank simultaneously by the different directions convection current, when each ingredients substance after all filling is finished in proportion, all pump into the secondary mixing tank again and promptly prepare and finish.

Claims (2)
