Description
Technical field
The present invention relates to a kind of automobile-used fuel burning of mixing, particularly a kind of dimethoxymethane composition.
Background technology
In order to solve the discharge of pernicious gas in vehicle exhaust, the quality of improving automobile-used oil product is effective method at present. Up to now, improve automotive oils quality and mainly contain two kinds of approach, one is to improve oil quality by oil refining, and a kind of is the quality of mixing fuel burning or additive and improve fuel oil by adding.
In vehicle fuel, add that to mix fuel burning be significantly to improve fuel oil quality, reduce the most effective approach of noxious gas emission in tail gas. Mixing at present fuel burning, to use more be Aalcohols fuel and ethers fuel. Aalcohols fuel comprises methyl alcohol, ethanol etc., but Aalcohols fuel exists the shortcoming such as low-temperature stratification, chance water stratification, in transport, storage, use, has a large amount of difficulties, and therefore ethers fuel has obtained paying close attention to widely.
Dimethyl ether has taken the lead in opening the application beginning that ethers is mixed fuel burning, but due under normal temperature and pressure, be gaseous state run into be difficult to application bottleneck. Dimethoxymethane, another name methylene dimethyl ether, formal, dimethoxym ethane etc., belong to ethers isomers, exists at normal temperatures and pressures with liquid state, because it exists without carbon-carbon bond and possessed the most efficient burnup characteristics in ether material with carbon-oxygen bond, possess good fuel oil and mix fuel burning character.
But the octane number of dimethoxymethane is lower than 90, and it is mixed fuel burning as motor petrol and uses the problem that does not reach motor petrol octane number standard that exists. The Chinese patent that is ZL200810045958.7 such as the patent No. discloses a kind of Dimethoxymethane gasoline, and it is made up of dimethoxymethane, benzene,toluene,xylene and gasoline, wherein dimethoxymethane is used as mixing fuel burning, has saved gasoline. Although this patent is by adding the aromatic hydrocarbon substance such as benzene,toluene,xylene to solve the low problem of dimethoxymethane octane number, but, benzene is a kind of to the virulent material of human body, and motor petrol national standard has strict restriction to its content, requires its mass fraction to be not more than 1.0%. Although aromatic hydrocarbons is the main contributions person of octane number, aromatic hydrocarbons also can increase the formation of engine aspirating system and combustion chamber deposit, and impels CO, HC discharge capacity to increase, and especially increases the discharge of benzene, and therefore motor petrol national standard is also controlled it. In a word, benzene,toluene,xylene etc., for the material that restriction in oil quality adds, 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 composition is provided, it uses as the automobile-used fuel burning of mixing, can save the use amount of gasoline, improve the heat utilization efficiency of fuel oil, reduce the discharge of pernicious gas in vehicle exhaust, and solved dimethoxymethane existing shortcoming when mixing fuel burning and use separately.
To achieve these goals, the technical solution used in the present invention is such:
As an automobile-used dimethoxymethane composition of mixing fuel burning, comprise the raw material of following weight portion composition: dimethoxymethane (DMM) 88-95 part, tert pentyl methyl ether (TAME) 5-8 part, functional additive 2-5 part; Wherein functional additive comprises the raw material of following weight portion composition: polyisobutenyl succimide 50-65 part, aliphatic acid 30-40 part, ceria 5-10 part.
Preferably, dimethoxymethane composition of the present invention comprises the raw material of following weight portion composition: 90 parts of dimethoxymethane (DMM), 5 parts of tert pentyl methyl ethers (TAME), 5 parts of functional additives; Wherein functional additive comprises the raw material of following weight portion composition: 55 parts of polyisobutenyl succimides, 35 parts, aliphatic acid, 10 parts of cerias.
Further, in order to improve the product quality of the present composition, reduce adding of impurity, dimethoxymethane content >=99% in above-mentioned DMM, methanol content≤0.5%; Tert pentyl methyl ether content >=99% in above-mentioned TAME.
Average grain diameter≤0.8 μ the m of ceria in described functional additive, can ensure cerium oxide particles in solvent, suspend form suspension, thereby make the catalytic activity of ceria higher.
The inventor is through many experiments discovery, although dimethoxymethane has efficient burnup characteristics, it is mixed fuel burning use as gasoline and has following shortcoming: the octane number of (1) dimethoxymethane, lower than 90, does not reach Fuel Petroleum octane number standard; (2) boiling point of dimethoxymethane is lower, causes its saturated vapor pressure higher, and easily producing vapour lock if directly use affects the normal fuel injection of engine; (3) oxygen content of dimethoxymethane is higher, is prone to localized hyperthermia and increases the discharge of oxynitrides while causing burning. Therefore the inventor is by adding a certain proportion of modifier and functional additive to solve the problems referred to above.
Tert pentyl methyl ether (TAME) has higher boiling point and octane number, and belong to ether material together with dimethoxymethane, it adds into can solve dimethoxymethane boiling point in dimethoxymethane simultaneously low and cause problem that saturated vapor pressure is high and because octane number is compared with the low problem that occurs that anti-knock properties are poor as modifier. But the addition of TAME is also to have certain limitation, inventor determines that by many experiments the addition of TAME is advisable at 5-8 weight portion, especially taking 5 weight portions as best, if the component of TAME is too low, octane number does not reach requirement, and the component of TAME is too high, because itself calorific value is lower than gasoline, the performance that can affect engine, meanwhile, also can increase the discharge of oxynitrides in automobile emission.
Consider that dimethoxymethane oxygen content is higher, the present invention adds cerium oxide particles therein simultaneously. Ceria and polyisobutenyl succimide and aliphatic acid form functional additive, ceria exists with suspended state in solvent, form suspension, thereby make it in the combustion process of internal combustion engine, form even burning and avoid localized hyperthermia by changing oxygen catalysis, thereby the discharge of oxynitrides is declined. And polyisobutenyl succimide is the cleaning agent with stronger divergent function, aliphatic acid is anti-sweller, the two combination has the effect of solvability to carbon distribution, therefore can prevent in fuel transfer system that pipeline is because carbon distribution stops up adding of functional additive, and ceria also can reduce the discharge capacity of oxynitrides.
Compared with prior art, the invention has the advantages that:
1, to have overcome dimethoxymethane boiling point lower in the present invention, causes the difficulty that saturated vapor pressure is higher, makes automobile-used mixing after fuel burning dimethoxymethane mixes in gasoline component can make internal combustion engine normally move.
2, dimethoxymethane composition of the present invention has stronger intersolubility than the automobile-used burning Aalcohols fuel (methyl alcohol, ethanol) of mixing, and meets water separating resistance and anti-cryogenic separation.
3, the present invention has overcome containing oxygen and has mixed fuel burning because its incomplete dissolving to carbon distribution causes the bottleneck of promoting the use of that oil circuit stops up, and the present invention can be come into the market rapidly as the Dimethoxymethane gasoline of mixing fuel burning.
4, the present invention mixes fuel burning and mixes after gasoline component, has greatly improved the heat utilization efficiency of gasoline component, also greatly reduces the noxious gas emission in vehicle exhaust simultaneously.
5, to mix the primary raw material dimethoxymethane production cost of fuel burning very low in the present invention, greatly improved the cost performance of Dimethoxymethane gasoline.
6,, because TAME can improve octane number, do not need to add and be intended to carry high-octane aromatic hydrocarbons component, so the present invention has avoided benzene,toluene,xylene etc. to affect adding of oil quality material.
