Description
Technical field
The present invention relates to a kind of vehicle fuel, more particularly, the present invention relates to a kind of alcohol hydrocarbon fuel composition for vehicular.
Background technology
Methyl alcohol oxygen molecule content is up to 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 byproduct light hydrocarbon, 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 alcohol hydrocarbon fuel composition for vehicular, 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 the mixture replacing automobile gasoline fuel of anhydrous methanol or dehydrated alcohol, lighter hydrocarbons (butane, pentane, hexane hydrocarbon mixture) and toluene or dimethylbenzene interpolation fluorocarbon surfactant, to improve the combustion heat value and the capability of antidetonance of fuel, capable of saving fuel again, also can reduce simultaneously the discharging of tail gas pollution, in petroleum resources nervous periods, contribution is arranged very.
Alcohol hydrocarbon fuel composition for vehicular of the present invention, the weight part of component is as follows:
Lighter hydrocarbons (butane, pentane, hexane hydrocarbon mixture) 100 weight parts
Methyl alcohol or ethanol 3-30 weight part
Solubility promoter 3-15 weight part
Cation fluorine carbon surface active agent 0.004～0.04 weight part
Said lighter hydrocarbons (butane, pentane, hexane hydrocarbon mixture) are the by-product topses of petrochemical industry refinery, 180# 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) toluene, the dimethylbenzene etc.;
MTBE, TAME, TBA are good gasoline antiknock Elixirs, and isopropylcarbinol is the volatility that solubility promoter also can improve gasoline.Toluene, dimethylbenzene are solubility promoter, also are octane values, the 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 or dehydrated alcohol are with respect to the lighter hydrocarbons (butane, pentane, hexane hydrocarbon mixture) of 100 weight parts, and addition is the 3-30 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 84, and the octane value of anhydrous methanol (RON) is 130; Anhydrous methanol uses 15 weight parts to add solubility promoter MTBE 5 weight parts and butane, lighter hydrocarbons (butane, pentane, hexane hydrocarbon mixture) 80 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, methyl alcohol 20 weight parts, mixed light-hydrocarbon 75 weight parts mix MTBE 5 weight parts, and its octane value is 93 units, and 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 MTBE 5 weight parts, and mixed light-hydrocarbon 70 weight parts, 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 solubility promoter 5 weight parts, and mixed light-hydrocarbon 65 weight parts, its octane value are fit to 9.5: 1～10: 1 engines of engine compression ratio and use 97, substitute No. 97 high standard gasoline.
Because anhydrous methanol or dehydrated alcohol and lighter hydrocarbons (butane, pentane, hexane hydrocarbon mixture) all can dissolve each other at normal temperatures, in the back layering easily of dissolving each other, particularly when steam temperature is lower than 15 ℃, mutual solubility is poor, at this shortcoming, can use fluorocarbon surfactant, this agent to have not only hydrophilic but also oleophilic characteristics, diffustivity is extremely strong, and uniformly attached to the interface of methyl alcohol and hydrocarbon polymer (hydrocarbon, 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 addition.The lighter hydrocarbons of phase Right what 100 weight parts (butane, pentane, hexane hydrocarbon mixture), solubility promoter use the 0-25 weight part also can, when temperature is higher, needn't adds solubility promoter and can reach purpose.
Said fluorocarbon surfactant is fluoroalkyl amine salt or quaternary ammonium salt cationic fluorocarbon surfactant, be selected from formula (1), (2) or (a kind of or its mixture in 3:
