Abstract
The present invention relates to the new methods that a kind of catalysis prepares gasoline alkylate.It is characterized in that with double-core
Description
Technical field
The present invention relates to a kind of preparation method of gasoline alkylate, in particular to a kind of polyetheramine ionic liquid is urged
The method that change prepares gasoline alkylate.
Background technique
Gasoline alkylate is by certain alkane alkene by iso-butane and C4 alkene than alkylated reaction occurs under the catalysis of acid
Be prepared, its main component is the mixture of C8 isoparaffin, mainly include trimethylpentane (TMP) and dimethyl oneself
Alkane (DMH), wherein the content of TMP is more, and the capability of antidetonance of gasoline alkylate is better.Gasoline alkylate has octane number high, steams
Air pressure is low, and arene content is lower, and the hardly series of advantages such as sulfur-bearing.This makes gasoline alkylate can be used as an ideal
Mixed composition and gasoline arrange in pairs or groups, then obtain that there is high-octane environmentally friendly gasoline.Currently, the alkylation vapour in the whole world
The yield of oil is 102,000,000 tons/year, but is only able to satisfy the whole world the desired amount of 10% or so, and produces the technology of gasoline alkylate
Still remain larger defect.Therefore, the clearer production technology of gasoline alkylate is each major company, the world and researchers weight
The project of point research.
Alkylated reaction usually along with polymerization reaction and cracking reaction, reduces the selectivity of C8 alkylate oil, higher
Alkane alkene than being the key that alkylated reaction is gone on smoothly with suitable acidity.Due to solubility of the iso-butane in acid system
It is extremely low, and alkene is soluble in acid system, the polymerization of alkene in order to prevent, alkylated reaction is usually required in high alkane/alkene ratio
Lower progress.It is just industrial as the gasoline alkylate production technology of catalyst using the concentrated sulfuric acid or hydrofluoric acid from the thirties in last century
Change and uses till today.Although technique is very mature, there are still many inevitable drawbacks for these strong acid catalysts.Example
Such as sour consumption is big, equipment seriously corroded, spent acid are difficult to handle, environmental pollution is serious.Solid acid catalyst can to equipment because of it
The corrosivity and hypotoxicity ignored, and excellent catalytic performance and higher selectivity are shown, cause the extensive of people
Concern.But the fatal defects of solid acid catalyst easy in inactivation in successive reaction, so that it is anti-in iso-butane/butene alkylated
Application pause in answering stays in laboratory stage.Therefore, a kind of efficient, environmental protection, safety, and alkylation can be recycled are found
Catalyst becomes the emphasis of contemporary scientific research.
In numerous catalyst for alkylation reaction, ionic-liquid catalyst is undoubtedly one of great potential.Due to its tool
There is steam to force down, nonflammable, thermal stability is high, and numerous inherent advantages, the people such as acidity is adjustable have been widely used in electricity
Chemistry, liquid/liquid extraction, numerous reactions such as catalysis and polymerization simultaneously achieve good effect.Then people make ionic liquid
It is applied in iso-butane/butene alkylation for catalyst and is filled with expectation.From 1994, Chauvin etc. first will
[C4mim]Cl–AlCl3] ionic liquid be used for catalyzing iso-butane alkane/butene alkylation, achieve better catalytic effect
Later, constantly to the type of ionic liquid, structure is designed and optimizes to reaction condition people, to reach more
Excellent effect.Studying more is metal chloride type Lewis acidic ionic liquid catalysts, although such catalyst is used for
Alkylated reaction has obtained preferable catalytic effect, but since it easily causes the irreversible inactivation of catalyst to water sensitive, therefore limits
Its industrialized development is made.

Alkane needed for low reaction/alkene ratio, substantially reduces cost of material.(3) by selecting different polyethers chain lengths, polyetheramine is adjusted
The viscosity of ionic liquid.The viscosity for adjusting ionic liquid is unlikely to excessive, has both kept also ensuring that the good solubilising of unstripped gas
Reaction is gone on smoothly；In addition it is important that, also to realize that the alkylate oil of generation is separated with ionic liquid automatically, is not required to
Want special processing step.(4) new catalyst system catalytic performance is superior, and reaction can be catalyzed under normal temperature and pressure, is wanted to equipment
It asks low, is advantageously implemented industrialized production.(5) ionic liquid and alkylate oil split-phase are good, and ionic-liquid catalyst can be efficient
It is recycled multiple.(6) hydrophobicity for utilizing polyetheramine ionic liquid, can also realize polyetheramine ionic liquid it is simple again
It is raw.A certain amount of water only need to be added into the ionic liquid being used for multiple times, the acid soluble oil in ionic liquid can be removed, it is real
The regeneration of existing ionic liquid.And in the regeneration of conventional ionic liquid, to use a large amount of organic solvent as extractant, water
Replace conventional organic solvent, not only significantly reduces operating cost, but also avoid environmental pollution.
The technical scheme of the present invention is realized as follows:
Using polyetheramine ionic liquid as catalyst, a certain amount of trifluoromethayl sulfonic acid, catalyzing iso-butane alkane and isobutene are added
