Background technology
C4 alkene and iso-butane are with various trimethylpentanes as main component through the technical octane that alkylated reaction is generated
High-knock rating gasoline harmonic component, technical octane has high-octane rating, the burning few and relatively low vapour pressure etc. of noxious products
Advantage.Alkylated reaction can be divided into alkyl sodium sulfate metallization processes and hydrofluoric acid alkylation technique, Fluohydric acid. according to used catalyst difference
It is volatile severe toxicity chemical drugs, once reveals and environment and production will be caused serious harm, and alkyl sodium sulfate metallization processes master
Wanting shortcoming is that the discharge capacity of spent acid is bigger.China's many employings alkyl sodium sulfate metallization processes, it is considered that determine that alkyl sodium sulfate metallization processes is anti-
The rate-determining steps answering speed is the alkane mass transfer to acid, and therefore in alkyl sodium sulfate metallization processes, the contact situation of acid hydrocarbon is extremely important
Performance variable.The main effluent refrigeration-type sulfuric acid alkylation that alkyl sodium sulfate metallization processes is Stratco company of the U.S. of mesh first two is anti-
Answering the cascade reactor alkyl sodium sulfate metallization processes of technique and Kellogg company of the U.S., both technique all fails to reach preferable
Acid hydrocarbon exposure level, greatly limit reaction rate, adds reactor size.In addition alkyl sodium sulfate metallization processes or one are strong
Exothermic reaction, reaction temperature rising can make by-product increase, affect alkylate oil quality.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that one can solve acid hydrocarbon contact problems in alkyl sodium sulfate metallization processes
And the device for alkylate oil synthesis of exothermic heat of reaction problem.
Technical scheme is summarized as follows:
A kind of device for alkylate oil synthesis, including reactor body 1, is provided with reactant in the bottom of reactor body
Charging aperture 9, is provided with concentrated sulphuric acid charging aperture 8 in the bottom of reactor body, and the middle part of reactor body is provided with sulphuric acid discharging

Middle and lower part within reactor body is provided with packing layer 2, makes the upper surface of packing layer be positioned at sulphuric acid discharging opening 3 and liquid phase discharging
Between mouth 7, make the lower surface of packing layer between concentrated sulphuric acid charging aperture 8 and reaction-ure feeding mouth 9, set below packing layer
Being equipped with liquid distribution trough 11, reaction-ure feeding mouth 9 is connected with liquid distribution trough 11 by pipeline, position in reactor body
Mist eliminator 4 it is provided with between liquid phase discharging opening 7 and gas phase discharging opening 6.
The preferred Pall ring filler of filler or ring intalox filler.
Liquid distribution trough preferred tubular liquid distributor, disc type liquid distribution trough or shower nozzle type liquid distribution trough, it is also possible to select other
Conventional liquid distribution trough.
The invention have the advantage that a kind of device for alkylate oil synthesis has preferably acid hydrocarbon contact effect, accelerate reaction rate
Reduce alkane alkene ratio simultaneously, and can strictly control reaction temperature, reduce the generation of byproduct of reaction, thus improve alkyl chemical combination
Become yield and the quality of oil, and the energy consumption needed for iso-butane circulation can be reduced.
Accompanying drawing illustrates:
Fig. 1 is the device schematic diagram for alkylate oil synthesis.
