Description
Technical field:
The present invention relates to a kind of biofuel that is applicable to oil engine and preparation method thereof, relating in particular to a kind of is the biological liquid fuel and preparation method thereof of major ingredient with the alcohols material.
Background technology:
The hydrocarbon fuel gasoline that the most of oil engine of China uses, diesel oil etc. all are to extract to make from oil, and oil is non-renewable resource.Therefore, become the novel energy that emphasis is promoted based on the Aalcohols fuel of alcohols material as renewable energy source, and form an industry gradually.At present, though there is the Aalcohols fuel of many types, the component complexity of most of Aalcohols fuel, price height, and preparation process complexity need special support equipment; Also have the part Aalcohols fuel just simply alcohols material to be mixed with hydrocarbon fuel, do not add any supplementary additive, this Aalcohols fuel mixed effect is poor, can not substitute gasoline and use.The patent No. 03130368.4 " Aalcohols fuel " discloses a kind of Aalcohols fuel, and its major ingredient is methyl alcohol, ethanol, propyl alcohol and ignition dope, and ignition dope is methylcarbonate or tricresyl phosphate.Though this Aalcohols fuel component is simple, good environmental protection is not owing to add any hydrocarbon fuel in its component, there is not the alcohols modifier yet, be fuel fully with the alcohols, because alcohols is different with the performance of hydro carbons, so this Aalcohols fuel can not mix use arbitrarily with gasoline; In addition, the manufacturing technique requirent of this Aalcohols fuel is higher, and fuel is synthetic can not to carry out at normal temperatures.
Summary of the invention:
The technical problem to be solved in the present invention is: provide that a kind of preparation technology is simple, raw material sources are abundant, cost is low, can substitute gasoline fully and be used in oil engine, also can arbitrary proportion and gasoline mix the biological liquid fuel that uses, to solve above-mentioned the deficiencies in the prior art.
The technical scheme that solves the problems of the technologies described above is: a kind of biological liquid fuel, and it is a mixture composed of the following components, each component concentration is calculated as by weight in the mixture:
Ethanol 500～600 weight part Virahols 6～8 weight parts

Methylcarbonate 1～3 weight part
Described ethanol, methyl alcohol are respectively industrial ethyl alcohol and industrial methyl alcohol; Described dimethylbenzene is p-Xylol or o-Xylol or both mixtures.
Another technical scheme of the present invention is: a kind of preparation method of biological liquid fuel, and it is that each component materials of forming biological liquid fuel of the present invention is mixed under normal temperature, normal pressure according to the following steps:
A, in ethanol, add the ethanol modifier: add 500～600 parts by weight of ethanol and 1～3 parts by weight of ethanol modifier pyridine in the reactor simultaneously, stir while feeding in raw material, treat the reinforced back continuation stirring 2～4 minutes that finishes, make the Denatured alcohol mixed solution;
B, add methyl alcohol: in the Denatured alcohol mixed solution of making, add 200～300 weight part methyl alcohol, stir, treat that the reinforced back that finishes continues to stir after 2～4 minutes, static 2～4 minutes, make first, alcohol mixeding liquid while feed in raw material;
C, add petroleum naphtha: in first, alcohol mixeding liquid, add 100～200 weight part petroleum naphthas, stir while feeding in raw material, treat the reinforced back continuation stirring 2 minutes that finishes, add 10～50 weight part dimethylbenzene again, stir while feeding in raw material, treat the reinforced back continuation stirring 2～4 minutes that finishes;
D, interpolation additive: in first, the alcohol mixeding liquid that has added petroleum naphtha and dimethylbenzene, add the Virahol of additive 6～8 weight parts and n-propyl alcohol, acetone, neopentyl glycol, each 1～3 weight part of methylcarbonate successively, stir while feeding in raw material, wait to feed in raw material to finish afterwards to continue to stir and promptly made the present invention's biological liquid fuel in 3～5 minutes;
E, packing, check: the biological liquid fuel of making is bottled or jar also check as required.
Because adopt technique scheme, the present invention has the following advantages:
1, raw materials cost is low, the source is abundant.Constituting main ingredient alcohols material of the present invention and can extract from materials such as corn, wheat, potato class, tangerine bar and make, also can extract from sugar waste, is renewable resources, can directly buy on market.Petroleum naphtha is the byproduct of refinery, and the present invention uses petroleum naphtha not only to utilize refuse as raw material, and has reduced cost, and all the other starting material all can directly be purchased from the market, and the source is abundant.
2, the feature of environmental protection is good, calorific value is high.Because the present invention is based on alcohols material, the alcohols material calorific value is than hydrocarbon fuel height, capable of reducing energy consumption, alcohols material is mainly based on carbon, oxygen in addition, can not produce the gas of contaminate environment such as sulfurous gas during burning, can reduce discharge of harmful gases in the exhaust gases of internal combustion engines, the every technical indicator of the present invention's biological liquid fuel and the method for inspection are referring to subordinate list one.
3, can substitute gasoline fully and be used in oil engine.The present invention is owing to added various additives, each component can well be mixed, also added pyridine as the ethanol property-modifying additive, changed the alcoholic acid proterties, make it more approaching, not only can substitute gasoline fully and be used in oil engine, can also mix with arbitrary proportion and gasoline and use with the proterties of hydrocarbon fuel, increase the kind of fuel, to remedy the supply shortage of natural fuel.
4, the preparation method is simple.Preparation method of the present invention is simple, does not need special support equipment, only needs raw material is dropped into mixing stirring in the reactor in proportion, can synthesize at normal temperatures and pressures.
