Description
Technical field
The present invention relates to gasoline, particularly a kind of Dimethoxymethane gasoline.
Background technology
In order to solve the discharge of obnoxious flavour in vehicle exhaust, the quality improving automobile-used oil product is most effective means at present.Up to now, improve automotive oils quality and mainly contain two kinds of approach, one improves oil quality by oil refining, and a kind of is mix fuel burning or additive and the quality of improving fuel oil by adding.
In vehicle fuel, add that to mix fuel burning be significantly improve fuel oil quality, reduce the most effective approach of noxious gas emission in tail gas.Mixing fuel burning at present, to use more be Aalcohols fuel and ethers fuel.Aalcohols fuel comprises methyl alcohol, ethanol etc., but Aalcohols fuel exists low-temperature stratification, meets the shortcomings such as water stratification, and transport, storage, use have a large amount of difficulty, and therefore ethers fuel obtains and pays close attention to widely.
Dme takes the lead in opening the application beginning that ethers mixes fuel burning, but encounters the bottleneck being difficult to apply owing to being gaseous state under normal temperature and pressure.Methylal(dimethoxymethane), another name methylene dme, formaldehyde dimethyl acetal, methylal etc., belong to ethers isomer, exist at normal temperatures and pressures with liquid state, possess the most efficient burnup characteristics in ether material because it exists with carbon-oxygen bond without carbon-carbon bond, possessed excellent fuel oil and mix fuel burning character.
But the octane value of Methylal(dimethoxymethane) is lower than 90, it is mixed fuel burning as motor spirit and uses the problem existing and do not reach motor spirit octane value standard.The such as patent No. is that the Chinese patent of ZL200810045958.7 discloses a kind of Dimethoxymethane gasoline, and it is made up of Methylal(dimethoxymethane), benzene,toluene,xylene and gasoline, wherein being used as mixing fuel burning by Methylal(dimethoxymethane), having saved gasoline.Although this patent solves the low problem of Methylal(dimethoxymethane) octane value by adding benzene,toluene,xylene, but, benzene is a kind of to the virulent material of human body, and motor spirit national standard has strict restriction to its content, requires that its massfraction is not more than 1.0%.Although aromatic hydrocarbons is the significant contributor of octane value, aromatic hydrocarbons also can increase the formation of engine aspirating system and combustion chamber deposit, and impels CO, HC quantity discharged to increase, and especially increase the discharge of benzene, therefore motor spirit national standard also controls it.In a word, benzene,toluene,xylene etc. are limit the material added in oil quality, therefore can not get applying widely.
Summary of the invention
Object of the present invention is just for above-mentioned the deficiencies in the prior art, a kind of Dimethoxymethane gasoline based on multiple non-GB gasoline component is provided, it is by mixing the combination of fuel burning Methylal(dimethoxymethane) composition and petroleum naphtha, high octane gasoline component, decrease the usage quantity of gasoline component, cost-saving, and improve the heat utilization efficiency of fuel oil, reduce the discharge of obnoxious flavour in vehicle exhaust, and solve Methylal(dimethoxymethane) separately as mixing shortcoming existing when fuel burning uses.
To achieve these goals, the technical solution used in the present invention is such:
Based on a Dimethoxymethane gasoline for multiple non-GB gasoline component, comprise weight percent be 10% ~ 30% automobile-usedly mix fuel burning, the petroleum naphtha of 40% ~ 70% and the high octane gasoline component of 10% ~ 30%;
The wherein automobile-used raw material mixed fuel burning and comprise following weight part composition: Methylal(dimethoxymethane) (DMM) 88-95 part, tert pentyl methyl ether (TAME) 5-8 part, functional additive 2-5 part; Described functional additive comprises the raw material of following weight part composition: polyisobutylene succinamide 50-65 part, lipid acid 30-40 part, cerium dioxide 5-10 part.
Above-mentioned petroleum naphtha is crude oil straight run, and its octane value is greater than 40.Crude oil is after time processing, and petroleum naphtha is topmost product, because time processing is still-process, belongs to physical refining process, so petroleum naphtha octane value is between 50 to 60, can not increase.
Above-mentioned high octane gasoline component is selected from aromizing gasoline component, isomerization gasoline component and gasoline alkylate component, and its octane value is greater than 90.Aromizing, isomerization and alkylation be existing maturation put forward high-octane complete processing.
Further, in order to improve automobile-used quality product of mixing fuel burning, reduce adding of impurity, Methylal(dimethoxymethane) content >=99% in above-mentioned DMM, methanol content≤0.5%; Tert pentyl methyl ether content >=99% in above-mentioned TAME.
Median size≤0.8 μm of cerium dioxide in described functional additive, can ensure that cerium oxide particles suspends formation suspension in a solvent, thus make the catalytic activity of cerium dioxide higher.
The present inventor finds through many experiments, although Methylal(dimethoxymethane) has efficient burnup characteristics, it is mixed fuel burning use as gasoline and there is following shortcoming: the octane value of (1) Methylal(dimethoxymethane), lower than 90, does not reach Fuel Petroleum octane value standard; (2) boiling point of Methylal(dimethoxymethane) is lower, causes its saturated vapor pressure higher, easily produces if directly use the normal fuel injection that vapour lock affects engine; (3) oxygen level of Methylal(dimethoxymethane) is higher, causes easily occurring localized hyperthermia when burning and increases the discharge of oxynitrides.Therefore the present inventor is by adding a certain proportion of properties-correcting agent and functional additive solves the problems referred to above.
Tert pentyl methyl ether (TAME) has higher boiling point and octane value, and belong to ether material together with Methylal(dimethoxymethane), it adds as properties-correcting agent and can to solve the low and problem causing saturated vapor pressure high of Methylal(dimethoxymethane) boiling point and occur the problem that anti-knocking property are poor because octane value is lower in Methylal(dimethoxymethane) simultaneously.But the add-on of TAME is also have a definite limitation, by many experiments, contriver determines that the add-on of TAME is advisable at 5-8 weight part, especially with 5 weight parts for the best, if the component of TAME is too low, then octane value does not reach requirement, and the component of TAME is too high, because itself calorific value is lower than gasoline, the performance of engine can be affected, meanwhile, also can increase the discharge of oxynitrides in automobile emission.
Consider that Methylal(dimethoxymethane) oxygen level is higher, the present invention adds cerium oxide particles wherein simultaneously.Cerium dioxide and polyisobutylene succinamide and lipid acid form functional additive, cerium dioxide exists with suspended state in a solvent, form suspension, make it form homogenous combustion by changing oxygen catalysis thus avoid localized hyperthermia in the combustion processes of oil engine, thus the discharge of oxynitrides is declined.And polyisobutylene succinamide is the sanitising agent with stronger divergent function, lipid acid is anti-swelling agent, the two combination has the effect of dissolving power to carbon distribution, therefore pipeline can be prevented in fuel transfer system to block due to carbon distribution adding of functional additive, and cerium dioxide also can reduce the quantity discharged of oxynitrides.
Petroleum naphtha is the basic component of gasoline concoction, and be an indispensable part, it has sulfur-bearing low, not containing alkene, and the advantages such as price is low, but its octane value is low, needs the high-octane component of proportioning when gasoline blending.But high-octane component price, can not use in a large number, for cost consideration, is limited in 10% to 30%.Mix fuel burning and belong to adding portion, the octane value of gasoline can be improved, increase the oxygen level of gasoline, change gasoline combustion processes within the engine, make fuel combustion more abundant, and reduce the discharge of engine objectionable impurities, but, be not the The more the better of interpolation, because the calorific value of its this life is high less than gasoline, a large amount of interpolation can increase automobile energy consumption, so control below 30%.
Compared with prior art, the invention has the advantages that:
1, instant invention overcomes Methylal(dimethoxymethane) boiling point lower, cause the difficulty that saturated vapor pressure is higher, Dimethoxymethane gasoline of the present invention has qualified saturated vapor pressure, can normally work in gasoline engine.
2, Dimethoxymethane gasoline of the present invention has stronger mutual solubility than alcohol gasoline (methanol gasoline, ethanol petrol), meets water separating resistance and anti-low ternperature separation process.
3, the octane value of Dimethoxymethane gasoline that the present invention prepares can reach the standard of GB gasoline, its power is stronger than the GB gasoline with label, fuel consumption is also less, and in vehicle exhaust, the quantity discharged of carbon monoxide CO and hydrocarbon polymer HC also declines greatly.
4, to mix the main raw material Methylal(dimethoxymethane) production cost of fuel burning very low in the present invention, substantially increases the cost performance of Dimethoxymethane gasoline.
5, because TAME can improve octane value, do not need to add and be intended to carry high-octane component, so present invention, avoiding benzene,toluene,xylene etc. affects adding of oil quality material.
