Description
Technical field
The invention belongs to petrochemical industry, specially a kind of alkylation reactor and alkylation reaction method, especially
Using sulfuric acid as the reactor and alkylation reaction method of catalyst isoparaffin and olefin alkylation reaction.
Background technology
With the increase of car ownership, vehicle exhaust is to the pollution getting worse of environment, thus to the pungent of motor petrol
More stringent requirements are proposed for alkane value and cleannes, this makes alkylation process and alkylate oil obtain extensive concern and attention.
Alkylation process is that a kind of important clean gasoline processing technology, product alkylate oil are non-conventions in oil refining process
The gasoline blend component thought, with no aromatic hydrocarbons, without alkene, low-sulfur, low-steam pressure, high-octane rating（RON 94~96, MON 92~
94）The advantages that.Current prevailing technology is liquid acid alkylation techniques, includes mainly sulfuric acid alkylation and hydrofluoric acid alkylation two
Kind, wherein since there is hydrofluoric acid very strong volatility and toxicity, China to run at present and in all sulfuric acid alkylations built
Method.In order to reduce side reaction, product quality is improved, sulfuric acid alkylation technological requirement operates at low temperature, due to sulphur under low temperature
Sour viscosity is big, extremely difficult miscible with iso-butane, thus the mixing of sour hydrocarbon is just at the focus on research direction of sulfuric acid alkylation technique.
Traditional alkylation reactor mainly uses mechanical agitation mode, as US3759318 proposes a kind of mechanical agitation
Formula acid hydrocarbon mixing reactor, reactor are provided with blender and stir the hybrid reaction for completing sour hydrocarbon by impeller high speed rotation, should
The disadvantage of method is to need high-speed stirred in sour hydrocarbon mixed process and consume a large amount of electric energy.US5443799 proposes one
Kind injection-type reactor is alkylated the technology of reaction, and feeding manner is first mixed with sulfuric acid for iso-butane and contacted again with alkene instead
It answers, i.e., iso-butane is sprayed by injector is mixed to form emulsion with sulfuric acid, and alkene carries out reverse haptoreaction with the emulsion again,
But make reaction temperature due to contacting effect etc. at it（8~20 DEG C）Higher, side reaction is serious.CN203295447U is proposed
A kind of shell and tube alkylation reactor, tube side are conversion zone, and shell side is heat exchange area, and tube body both ends are respectively pre- distributed areas
Region is flowed out with reactant, which is suitable for isoparaffin and low-carbon alkene and generates Gaoxin under liquid acid catalyst effect
The reaction of alkane value alkylate oil, since this method is conventional shell-and-tube reactor, that there are device structures is complicated, formation efficiency is low,
The problems such as material side reaction is serious in pipe.
Packing reactor is a kind of new alkylation reactor, as CN201410175970.5,
CN201310140601.8, CN201510738217.7, CN201210100634.5 etc..By taking CN201210100634.5 as an example,
The document discloses a kind of alkylation reactor, it is made of, fills out one section or more the structured packing with cavity structure in reactor
The cavity of material is provided at both ends with coolant distribution pipe, forms heat transfer zone in cavity, forms reaction zone between cavity and cavity, reacts
Area and heat transfer zone are arranged in reactor radially alternating, and reaction zone and heat transfer zone are not communicated with.Existing material filling type alkylation reactor
Although haveing a certain upgrade in certain sport technique segments tool, comprehensive performance still needs to further increase.
From the point of view of current technology development both at home and abroad, the research of new sulfur acid alkylation processes is sour based on improving mostly
Hydrocarbon mixability strengthens mass transfer, accelerates reaction rate, and how continuous and stable remove reaction heat, keep reaction process temperature,
The direction of side reaction is reduced, but still is had the following problems：（1）Since alkylated reaction is exothermic reaction, material is unevenly distributed
（Including radial material distribution and axial material are distributed）The side reaction that can aggravate olefinic polymerization occurs, and influences the product of alkylate oil
Quality；（2）Since sour hydrocarbon is immiscible, and the viscosity of acid is big, and the interfacial mass transfer resistance in the alkylation process for being is big, passes
Matter and reaction rate are low, it is therefore desirable to which the surface area for providing sour hydrocarbon reaction simultaneously, provides the mass transfer force of reaction mass also ten
Divide important；（3）Reaction heat in reaction process（Including radial reaction heat and Axial response heat）It needs to remove in time, otherwise can go out
Existing hot localised points occur side reaction and reduce reaction efficiency, and more satisfactory mode is that reactor maintains original state always
Isothermal reaction process, but actually can only be infinite approach and be unable to reach.
In conclusion for alkylation process, exploitation is a kind of uniform, anti-along the radial and axial temperature of reactor
Efficient, side reaction is answered to lack reaction process and equipment, with overcome the deficiencies in the prior art, for the advanced of alkylated reaction technology
Property and high efficiency are of great significance.
