Abstract
The invention relates to a methanol gasoline which can be mixed with regular gasoline at a random ratio for using without modifying automobile fuel injection systems. The methanol gasoline is composed of, by weight, 82 to 88 parts of methanol, 2 to 4 parts of a modifier, and 10 to 14 parts of a calorific value increasing agent. The methanol gasoline possesses following advantages compared with conventional methanol gasoline: the methanol gasoline can be used alone, or can be mixed with national standard No.93 gasoline at a random ratio for using, and no vehicle modification is needed; no corrosion on oil pumps, oil systems, and oil atomizer nozzles is caused, and complete cleaning of vehicle fuel injection systems is not necessary for the first time of using; power of vehicles provided with the methanol gasoline is higher than powder of the same vehicles provided with national standard No.93 gasoline, and using energy consumption of a vehicle provided with the methanol gasoline is equal to that of a same vehicle provided with gasoline; swelling action of the methanol gasoline on plastic cement and swelling action of gasoline on plastic cement are the same; and when the methanol gasoline is mixed with gasoline, layering or emulsifying of the methanol gasoline is not caused even when the methanol gasoline is mixed with 3%, by mass, of water.
Description
Technical field
The present invention relates to a kind of vehicle fuel, be specifically related to a kind of methanol gasoline.
Background technology
Gasoline is normally raw material with oil, refines obtain C through multiple tracks technique
4-C
12aliphatic hydrocarbon and cyclic hydrocar-bons, methanol gasoline is then fuel based on Coal Chemical Industry Methanol product, more composite base gasoline, additive and the mixture obtained.The great advantage of methanol gasoline to reduce motor vehicle exhaust obnoxious flavour total amount, more cleans and be conducive to environment, therefore become study hotspot than traditional gasoline.
But when using large-proportion methanol gasoline (i.e. the methanol gasoline of methanol content more than 30%) in prior art, mainly contain following two kinds of defects: 1, use during methanol gasoline and electronic double controlled system must be installed, former car engine system is reequiped, this turn is carried out to injection system, increase its fuel charge, and when automobile power is not enough, conversion uses traditional base gasoline automatically; 2, the oil pump of resistance to alcohol using specialty is needed.
Vehicle through repacking uses methanol gasoline also to there will be following problem: 1, be short of power: show vehicle driving up, driving of turning on the aircondition, speed per hour is more than 100 kilometers; 2, energy consumption is large: compared with No. 93 conventional gasoline, observable index reaches 1:1.8, and some vehicle reaches 1:2(and namely travels 100 kilometers of consumption 10 liters, gasoline with a car, consumes 18 liters-20 liters with methyl alcohol).
Cause the reason of these defects and problem to be: methyl alcohol calorific value is low, and calorific value is 4650 kilocalories, and gasoline is 10200 kilocalories, and low the determining of calorific value is short of power, after changing engine system, increase fuel charge, cause energy consumption to increase; Methyl alcohol separates in transport and storage middle reaches and solves Jia Chuo and formic acid, first has very strong corrosive nature, specifically corrosive nature is had to oil pump, oil circuit and cylinder body, have corrosive nature to oil pump, oil circuit and cylinder body, methyl alcohol has stronger washing and solubility property, has cleanup action to the iron rust in fuel tank, oil circuit, dirt, colloid, cause oil circuit and fuel injection nozzle blocking, affect normal fuel injection, usual common oil pump monthly needs to change once, and the oil pump of resistance to alcohol changes once for 3 months; Fuel injection nozzle easily blocks, and to plastic cement swelling in oil piping system, has corrosion to oil pump, oil circuit, engine cylinder-body; Use first and must clean vehicle oil way system; Moisture time used in combination with gasoline in air enters after gasoline reaches 1%, and methanol gasoline demixing phenomenon will occur.
Summary of the invention
For above-mentioned the deficiencies in the prior art part, the object of the present invention is to provide and a kind ofly can to use with any proportioning of regular gasoline, do not need methanol gasoline that automobile injection system is reequiped.
For achieving the above object, the technical solution used in the present invention is: a kind of methanol gasoline is made up of following parts by weight of component: methyl alcohol 82-88 part, properties-correcting agent 2-4 part, heat value agent 10-14 part.
The purity of methyl alcohol should be massfraction and is more than or equal to 99.9%; Properties-correcting agent is the reagent playing katalysis when methanol gasoline burns, as fatty acid magnesium etc., or/and play the reagent of solublization, as alcohol compound, methyl tertiary butyl ether etc.; Heat value agent can improve the reagent of the combustion utilization efficiency of methanol gasoline, as benzene-like compounds, methylethyl ketone peroxide etc.
Preferred further, described methanol gasoline is made up of following parts by weight of component: methyl alcohol 85 parts, properties-correcting agent 3 parts, heat value agent 12 parts.
Further, described properties-correcting agent comprises following parts by weight of component: dehydrated alcohol 25-35 part, Virahol 15-25 part, ethyl acetate 25-35 part, trimethyl carbinol 15-20 part, tween 80 0.2-0.4 part, petroleum sodium sulfonate 0.2-0.4 part, benzotriazole 0.2-0.4 part, pyrazolone 0.05-0.15 part.
Tween 80 and Tween-80 are conventional emulsifying agent; Petroleum sodium sulfonate is alkyl sodium sulfonate, is generally the alkyl sodium sulfonate containing 14-18 carbon atom; Benzotriazole and benzotriazole; Pyrazolone and 5-pyrazolone, also known as 5-pyrazolone, English name 5-pyrazolone, its molecular structural formula is:
Preferred further, described properties-correcting agent comprises following parts by weight of component: dehydrated alcohol 30 parts, Virahol 20 parts, ethyl acetate 30 parts, the trimethyl carbinol 19 parts, tween 80 0.3 part, petroleum sodium sulfonate 0.3 part, benzotriazole 0.3 part, pyrazolone 0.1 part.
Further, described heat value agent comprises following parts by weight of component: pentane 7-13 part, hexane 7-13 part, dimethylbenzene 35-45 part, sherwood oil 35-45 part.
Preferred further, described heat value agent comprises following parts by weight of component: pentane 10 parts, hexane 10 parts, dimethylbenzene 40 parts, sherwood oil 40 parts.
The preparation method of described methanol gasoline comprises step:
A, dehydrated alcohol, Virahol, ethyl acetate, the trimethyl carbinol added stir in reactor after, then add tween 80, petroleum sodium sulfonate, benzotriazole, pyrazolone, then stir, leave standstill and namely obtain properties-correcting agent after at least 24 hours;
