Technical field
The present invention relates to a kind of vehicle fuel, in particular, the present invention relates to a kind of Vehicular light hydrocarbon fuel composition.
Background technology
Methyl alcohol oxygen molecule content reaches 50% (gasoline oxygen molecule content is 0), combustionvelocity 52 meter per seconds (M/S) (gasoline 38M/S), the methyl alcohol combustion heat value have only gasoline half, after methyl alcohol and hydrocarbon polymer (hydrocarbon) fuel mix, burn in cylinder, because rate of combustion is fast, engine cylinder mean effective pressure force rate uses gasoline to improve, therefore use identical amount, the distance that automobile runs is identical with use gasoline.
Methyl alcohol is the product of coal, gas production, and 1.5～1.8 tons of coals can be made 1 ton of methyl alcohol, and cost is than low many of gasoline, and price has only gasoline about 40% No. 90.Lighter hydrocarbons (butane, pentane, hexane hydrocarbon mixture) are petrochemical industry refinery byproducts, and because of octane value is low, volatilization is exceedingly fast, so can not directly use as motor spirit.How with methyl alcohol and the combination of petrochemical industry refinery lighter by-products, making it can be used as vehicle fuel is the very problem of concern of people institute.
Summary of the invention
The technical issues that need to address of the present invention are to disclose a kind of Vehicular light hydrocarbon fuel composition, to overcome the defective that prior art exists.Satisfy the needs of relevant field development.
Technical conceive of the present invention is such:
The present invention's imagination is with anhydrous methanol or dehydrated alcohol, lighter hydrocarbons (butane, pentane, hexane hydrocarbon mixture) and toluene or dimethylbenzene or produce the shifting block oil of toluene and the mixture replacing automobile gasoline fuel of light aromatics interpolation fluorocarbon surfactant, to improve the combustion heat value and the capability of antidetonance of fuel, cost is low, capable of saving fuel again, also can reduce simultaneously the discharging of exhaust pollutant, in petroleum resources nervous periods, contribution is arranged very.
Vehicular light hydrocarbon fuel composition of the present invention, the weight part of component is as follows:
Lighter hydrocarbons 100 weight parts
Anhydrous methanol or dehydrated alcohol 1-100 weight part
Solubility promoter 0-52 weight part
Aromatic hydrocarbons (tops and the light aromatics of toluene, dimethylbenzene or production toluene) 3-100 weight part
Cation fluorine carbon surface active agent 0.004-0.04 weight part
CMT (cyclopentadiene tricarbonyl manganese) 0-0.66 weight part
Said lighter hydrocarbons (light alkanes) are the hydrocarbon mixture of butane, pentane and hexane, are the by-product topses of petrochemical industry refinery, lightweight solvent oil, products such as C5 component, for example the pentane cut separated of natural gas condensate;
Said solubility promoter is selected from methyl tertiary butyl ether (methyl tert-butyl ether, MTBE), tert amyl methyl ether(TAME) (methyl tertamyl methyl ether, TAME), a kind of in tertiary butyl alcohol (tert-butylalcohol, TBA) or isopropylcarbinol (iso-butanol) etc.;
MTBE, TAME, TBA are good gasoline antiknock, and isopropylcarbinol is the volatility that solubility promoter also can improve gasoline.Toluene, dimethylbenzene are solubility promoter, also are octane value, combustion heat value improving agent.
It is anhydrous methanol more than 99.5% that said anhydrous methanol must adopt weight purity, and its rule of origin is handled through removing moisture content in coal or Sweet natural gas, and anhydrous methanol be one of future source of energy of mankind's expectation.Anhydrous methanol, dehydrated alcohol, MTBE, TAME, TBA, isopropylcarbinol etc. are oxygenatedchemicals again, can allow the burning of alcohol hydrocarbon fuel composition more complete, also help the improvement of environmental pollution.
Anhydrous methanol or dehydrated alcohol are with respect to the lighter hydrocarbons (butane, pentane, hexane hydrocarbon mixture) of 100 weight parts, and addition is the 1-100 weight part, and its addition system decides according to the octane value (RON) of employed lighter hydrocarbons.For example the octane value of lighter hydrocarbons (RON) is 82, and the octane value of anhydrous methanol (RON) is 110; Anhydrous methanol uses 15 weight parts to add aromatic hydrocarbons 15 weight parts and lighter hydrocarbons (butane, pentane, hexanes mixtures) 70 weight parts, the octane value (RON) that can obtain the methyl alcohol light-hydrocarbon fuel is 90, the general engine compression ratio that is fit to is that 9.0: 1 following automobiles use, and substitutes No. 90 gasoline.
Moreover, anhydrous methanol 20 weight parts, mixed light-hydrocarbon 70 weight parts, BTX aromatics 10 weight parts, CMT 0.0025 weight part, its octane value are 93 units, suitable engine compression ratio is that 9.3: 1 following automobiles use, and substitutes No. 93 gasoline.Anhydrous methanol 25 weight parts add solubility promoter MTBE5 weight part, mixed light-hydrocarbon 60 weight parts, and aromatic hydrocarbons 10 weight parts, CMT 0.0025 weight part, its octane value are 95 units, are fit to 9.5: 1 automobiles of engine compression ratio and use, and substitute No. 95 gasoline.Anhydrous methanol weight part 30 adds aromatic hydrocarbons 25 weight parts, and mixed light-hydrocarbon 45 weight parts, its octane value are fit to 9.5: 1～10: 1 engines of engine compression ratio and use greater than 97, substitute No. 97 normal benzenes.
Because anhydrous methanol or dehydrated alcohol and lighter hydrocarbons (butane, pentane, hexane hydrocarbon mixture) all can dissolve each other at normal temperatures, in the easily layering of back of dissolving each other, particularly when steam temperature is lower than 15 ℃, mutual solubility is poor, at this shortcoming, can use fluorocarbon surfactant, this has not only hydrophilic but also oleophilic characteristics, diffustivity is extremely strong, and uniformly attached to the interface of methyl alcohol and hydrocarbon polymer (lighter hydrocarbons, aromatic hydrocarbons) molecule, and, stronger protection against corrosion, antirust and anti-wear effect are arranged at metal and the thin film of rubber surface formation one deck; Use solubility promoter to solve this problem in case of necessity.And anhydrous methanol or dehydrated alcohol and lighter hydrocarbons are when temperature is more than 15 ℃, and mutual solubility is better, therefore need to reduce the solubility promoter dosage.With respect to the lighter hydrocarbons (butane, pentane, hexane hydrocarbon mixture) of 100 weight parts, solubility promoter use the 0-52 weight part also can, when temperature is higher, needn't add solubility promoter and can reach purpose.
Aromatic hydrocarbons comprises toluene or dimethylbenzene or its mixture, the tops of production toluene, light aromatics etc.
Said fluorocarbon surfactant is fluoroalkyl amine salt or quaternary ammonium salt cationic fluorocarbon surfactant, is selected from a kind of or its mixture in formula (1), (2) or (3):
