Description
Technical field
A kind of method for improving catalytic cracking unit yield of gasoline, belong to the catalytic cracking technology field of petroleum refining.
Background technology
When catalytic cracking unit performs the condition of production of voluminous gasoline, mainly from raw material, catalyst, reaction depth, product
Extract etc. improves gasoline yield.The method that gasoline yield is improved by improving raw material composition mainly improves lightweight in raw material
Oil product（Such as wax oil）Content, reduce as far as possible and be not easy to crack the residual oil of component, refined rich in condensed-nuclei aromatics, colloid, asphalitine etc.
Wax tailings mix refining ratio.At present, crude oil increasingly in poor quality, the oil plant to be processed of catalytic cracking unit are also more difficult to add
Work, this method can not fundamentally solve the problems, such as that raw material is overweight.
The method for emulsifying catalytically cracked material has the research of more than 30 years abroad, also there is 10 years of researches at home
History, but laboratory scale is basically limited at present.Theoretically and laboratory's data are explainable, after Emulsified,
The progress of catalytic cracking reaction will be greatly promoted, improves reaction depth, improves product distribution.
In a kind of method of existing pretreating catalytic conversion hydrocarbon oil crude material, using by emulsifying agent, passivator, stabilization aid
Emulsifier emulsification is sent into the catalytically cracked material of water, catalytic cracking reaction, vapour are carried out in 2kg/h riser middle- scale device
Oil, light oil, the yield of total liquid yield are all than not emulsified raw material increase.Also in the prior art, catalytically cracked material is multiple
In the presence of co-emulsifier, after mulser emulsifies, catalytic cracking reaction is carried out, also improves gasoline, diesel oil, light oil and total
Liquid receives yield.But prior art is all under normal pressure and lower temperature（Less than 100 DEG C）Catalytically cracked material is emulsified, and in industry
In production process, the preheating temperature of catalytically cracked material is generally higher, reaches 140 DEG C ~ 220 DEG C or so, is difficult at this temperature
Stable emulsification state is formed, and when the oil emulsion formed under normal pressure, low temperature enters nozzle under the feeding temperature of catalytic unit
The fluctuation of pressure at nozzle is easily caused, it is unfavorable to producing.Now lack a kind of vapour of raising catalytic unit that can be by a relatively large margin
Oil yield, while improve catalytically cracked gasoline motor method and the technology of research octane number (RON).
The content of the invention
The technical problem to be solved in the present invention is：Overcome the deficiencies in the prior art, there is provided one kind improves catalytic cracking feeds
Dispersiveness and fogging degree and cracking level it is high raising catalytic cracking unit yield of gasoline method.
The technical solution adopted for the present invention to solve the technical problems is：The side of the raising catalytic cracking unit yield of gasoline
Method, it is characterised in that：It will treat that catalytically cracked material, water and emulsifying agent first enter back into emulsifying device emulsification through premixer mixing,
The mass ratio for treating catalytically cracked material, water and emulsifying agent is 88 ~ 89.7：8.5~10：1.8 ~ 2, the oil emulsion of gained is straight after emulsification
Tap into and carry out catalytic reaction into catalytic unit；Emulsification condition is in the emulsifying device：In cutting for 6000r/min ~ 8000r/min
While cutting stirring, pressure 1.3MPa ~ 1.4MPa in emulsifying device, 180 DEG C ~ 195 DEG C of temperature are kept.
Emulsification condition more universal at present is typically all the vapourizing temperature in normal pressure and water（100℃）Under emulsified,
But preheating temperature of the obtained oil emulsion in catalytic cracking on this condition（140-220℃）Lower is difficult to keep stable state,
It is just vaporized before oil emulsion enters catalyst cracker nozzle, both do not reach the purpose of " microexplosion ", and cause nozzle again
Locate pressure oscillation, influence catalytic cracking normal operating and nozzle life.Before catalytic unit feed nozzle increase newly premixer and
The efficient emulsifying device of profit, specified temp and the catalytically cracked material of pressure are mixed with emulsifying agent and water and mixed by premixer

Oil emulsion is by primary atomization, and because the boiling point of water and oil difference is larger, water first vaporizes, and volume drastically expands, and generates huge
Pressure, moment pop oil droplet, become many small oil droplets, and this process is referred to as " microexplosion " or secondary-atomizing.Secondary-atomizing carries
The high atomizing effect of catalytically cracked material, greatly improves contact of the raw material with catalyst, improves the vaporization rate of feedstock oil,
So as to improve catalytic cracking reaction effect, catalytic cracking unit yield of gasoline is improved, while improve catalytically cracked gasoline motor method
And research octane number (RON).
