Description

A kind of methanol fuel for vehicles

Technical field

The present invention relates to the fuel oil technology, is a kind of methanol fuel for vehicles specifically.

Background technology

In recent years, exhaustion day by day along with petroleum resources, the violent upheaval of oil market, oil extraction and stock are extremely unstable, relation between market supply and demand is unbalance, oil price soars again and again, cause the price of gasoline product to rise steadily, oil consumption has become a large number of expenditure in the daily life consumption, problems such as tail gas pollution is serious day by day in addition, people have more and more tended to highly effective energy-conserving environmental-protecting type lead-free synthetic gasoline---Aalcohols fuel oil, but because technical problem, methyl alcohol more is difficult to dissolve in a large number gasoline than ethanol in addition, comprise Japan, Germany, gasoline substantially all can only be sneaked into the methyl alcohol below 15% by various countries such as the U.S. in the exploitation of methanol gasoline, its shortcoming is existing methanol gasoline cost height, mutual solubility is poor, adding proportion is few, causes vapour lock and poor stability easily, spatter property is not high, to use the finished product wet goods, reach economical far away, environmental protection, green fuel and complete standard-required without processed oil are not suitable for extensively promoting the use of.

Summary of the invention

Purpose of the present invention is intended to improve the weak point in the prior art, provides that a kind of methyl alcohol occupancy volume is big, oil property good, methanol fuel for vehicles with low cost.

Technical scheme of the present invention is: a kind of methanol fuel for vehicles, and it contains (by weight percentage) methyl alcohol 15-50%, hydro carbons 15-55%, gasoline product 0-59%, methyl tertiary butyl ether 2-6% mixes benzene 3-8%, sanitas 0.4-0.6%, fire retardant 0.05-0.15%, lubricant 0.2-0.5%.

Described hydro carbons can be in direct current oil, petroleum naphtha, lightweight oil, the solvent oil any.

Above-mentioned methanol fuel for vehicles, it can also contain vapour pressure adjustment 0.2%.The effect that vapour pressure is adjusted is, 5-9 month envrionment temperature height, and the azeotropic point of methanol gasoline is low, and vapour pressure raises, and is easy to generate vapour lock, makes the engine cisco unity malfunction, has added after vapour pressure adjusts, and can reduce saturation vapour pressure.Vapour pressure is adjusted can be any one or two kinds of or two or more mixture in butanone, methyl propionate, propyl formate, methyl alcohol isobutyl ester, dipropyl ether, the hexanaphthene.

Compared with the prior art the present invention has outstanding substantive distinguishing features and progressive significantly: because each reasonable mixture ratio of components of the present invention, make dissolving in occupancy volume and can reaching 15-50% of methyl alcohol, occupy ratio considerably beyond existing methyl alcohol and be up to 15% level, methyl alcohol usage ratio technology realizes important breakthrough, even can also be fully need not existing gasoline product, break away from dependence, to the imbalance between supply and demand of alleviating petroleum products, solve problem such as energy deficiency and played vital role to oil.Processed oil of the present invention after testing, the product octane value surpasses 90, label can reach 90#, 93#, 95#, more than the 97#, have good anti-knocking property and stability, suitable vapo(u)rability, multiple advantages such as excellent spatter property and non-corrosiveness; After various vehicle numbers showed with thousand actual uses, use oil fuel of the present invention, engine easily started, dynamic property is strong, engine mildness, and noise is few, oil consumption is compared with similar label gasoline and is saved more than 10%, and this production engine of life-time service does not produce carbon distribution and colloid; Compare elimination carbon distribution 80-100% with similar gasoline, mechanical wear is little, improves power 15-20%; Compare with conventional gasoline, it is more abundant to burn, carbon monoxide, hydrocarbon polymer in the tail gas obviously reduce, the tail gas index is compared with national standard and is lower than 40-60%, and owing to raw material is easily purchased, easily stores, easily produced, with low cost, correspondingly reduced the price of processed oil, really belong to economic environment-friendly fuel, have good social benefit and economic benefit, be fit to very much promote the use of.

Below in conjunction with specific embodiment the present invention is done at length and to explain.
