Description

Gasoline of mixing fuel burning mixed fuel burning and contains this by a kind of gasoline

Technical field

The present invention relates to clean fuel field, particularly gasoline of mixing fuel burning mixed fuel burning and contains this by a kind of gasoline.

Background technology

Along with society and expanding economy, the recoverable amount of automobile is increasing; Meanwhile, the ratio that emission from vehicles accounts in atmosphere pollution factor for the pollution of air is increasing. In order to alleviate the air pollution day by day increasing the weight of, clean fuel oil becomes the important directions of people's research.

In existing research and application, except the discharge of the improvement by PETROLEUM PROCESSING technique with less Vehicular exhaust, another important direction is to add and mix fuel burning in existing fuel oil, promotes on the one hand automobile power and reduces fuel consume, can reduce on the other hand exhaust emissions.

Existing research shows, polymethoxy dimethyl ether (DMM_n), have that (molecular formula is CH with diesel oil core component alkane₃(CH₂)_nCH₃) closely similar molecular structure, polymethoxy dimethyl ether general structure is CH₃O(CH₂O)_nCH₃, according to the similar general principle mixing, the intersolubility of itself and diesel oil is good;

Meanwhile, DMM_nThere is higher oxygen content (42%～49%) and higher Cetane number (DMM_3～8Cetane number all more than 78); Polymethoxy dimethyl ether (DMM_n) oxygen atom be combined with singly-bound with carbon atom, in conjunction with can be higher, easily activation forms the molecule with oxidative function, mixes at diesel oil the difficulty that has overcome burning anoxic and few oxygen in burning process, makes the engine combustion efficiency and heat utilization efficiency increase of motor vehicles. Causing carbon monoxide, hydrocarbon and soot decline in the tail gas of motor vehicles discharges, is a kind of clean energy resource of energy-saving and emission-reduction;

So lot of documents has been reported DMM_n, wherein n >=3, especially DMM_3～8Being suitable as the fuel burning of mixing of diesel oil, reporting such as the Chinese patent application of CN103666598A, is the diesel oil that a class is good is mixed fuel burning.

But, at DMM_nManufacture process in, generally all can have DMM₁And DMM₂Generate. In prior art, only has DMM_n≥3, especially DMM_3～8Mix burning for diesel oil, even in gasoline additive, be also the polymethoxy dimethyl ether that uses n >=3, as the Chinese patent application of CN103695047A is reported.

That is to say, at DMM_nManufacture process in the DMM that produces₁And DMM₂Because prior art does not find suitable purposes, thereby be all generally again to enter course of reaction as reactant finally also will need separation to remove as byproduct of reaction, make so on the one hand DMM_nManufacture process numerous and diverse, production efficiency is low, also makes on the other hand DMM_nTo prepare productive rate low, value-added content of product is low.

Summary of the invention
