Abstract

The invention relates to a kind of substitute for petrol and preparation method thereof, it can pass through reconstructed coal, it is 1-12 hydrocarbon oxygen compound that Sweet natural gas, petroleum gas, refinery gas, biogas get carbonatoms, is prepared than four or more this compound by different volumes then to obtain.The present composition is used for substituting the fuel of gasoline as oil engine, has the character and the function of gasoline, and burning is more complete, institute's waste discharge tolerance is far below gasoline, can play under need not any utility appliance to prolong internal-combustion engine life-span and reduce effects such as environmental pollution.

Description

The present invention is on a kind of substitute for petrol for being used as new energy and preparation method thereof, more specifically the composition that regular price gasoline is used as fuel is substituted on a kind of, the substitute for petrol is particularly suitable for using in internal combustion engine, do not damage machine with nontoxic, complete burning, combustor service life and the features such as reduce environmental pollution in extension, and the present invention can be according to the composition that different qualities are configured to the need for difference.

As developing rapidly for modernization industry improves constantly with automaticity, the mankind are growing day by day to the demand of the energy, and tap a new source of energy the purpose that always people pursue.The appearance of oil has carried out huge revolution as internal combustion engine invention to mankind's civil zone, but but day by day exhaustion can not meet the demand of current and future world for oil production rate and storage.It is also day by day short as the gasoline of oil staple product, so far there are no the product substituted.

But on the one hand be the energy shortage, on the other hand again be that the energy fails abundant reasonable employment, such as substantial amounts of casing-head gas and without right gas due to transport factor, the effect utilized is not very high.Simultaneously with the industrial use of a large amount of fuel, the engine exhaust as used in communications and transportation goes out substantial amounts of waste gas, reduces the quality of the environmental factors such as big gas and water, directly threatens the health and safety of the mankind.In order to overcome energy shortage and environmental pollution, the numerous method of many personages' propositions existing so far and measure.By using natural gas, the base stock such as casing-head gas prepares various industrial chemicals, and product also not under it is hundreds of, but the person that makees automotive fuel can be directly used in（Such as motor vehicle fuel）There is presently no for the certainly environmental pollution that is situated between, it is to avoid motor vehicle emission poisonous fume, and exhaust device is handled provided with more than tens of kinds.But in fact all not up to be enough to overcome the stage of these problems, the problem of fundamentally solving this two aspect.

The present invention problem be exactly be situated between determine two present on problems there is provided a kind of substitute for petrol as new energy.Said composition can not only replacing gasoline completely purposes, be completely suitable for all with the system of gasoline, moreover it is possible to reduce waste discharge tolerance and play Environmental Role.

It is an object of the invention to provide a kind of composition for being used to replace gasoline, it is combined by the hydrocarbon oxygen compound of different molecular weight and is made, and wherein the carbon number of compound is 1 to 12, and number of hydrogen atoms is 2 to 24, and oxygen atomicity then 0 to 3.

Another object of the present invention is to provide a kind of composition of substitute for petrol, said composition has the property and function similar to gasoline, in the internal combustion engine that may be used in gasoline, and acquisition is enough satisfied effect, in the case of internal combustion engine is played without any servicing unit, reduce or avoid it to discharge waste gas, such as CO, NO, NO₂, SO₂, SO₃Deng so as to environmental protection.

Further object of the present invention is to provide a kind of method for preparing substitute for petrol, and any four or more compound stirring is combined among alkane, unsaturated hydrocarbons, aromatic hydrocarbon, alcohol ether, aldehyde ketone and ester.

Compound for raw material of the present invention can be for alkane such as：
