And system.
Background technology
Global Oil resource heaviness trend aggravates, catalytic cracking (Fluid catalytic cracking, FCC) conduct
Processing of heavy oil deep technical also increasingly seems important.More than 1.5 hundred million tons, the yield of slurry oil accounts for China's catalytic cracking year processing capacity
The 5%~10% of catalytic cracking treating capacity, catalytic cracking byproduct slurry oil yield also increase year by year.The property of catalytic cracked oil pulp
Extremely special, component is based on condensed-nuclei aromatics, the general not alkyl side chain of belt length, and average molecular mass is larger, left 500
The right side, it is slightly lighter than subtracting slag.Catalytic cracked oil pulp is inferior heavy oil, wherein containing substantial amounts of catalyst granules, if directly applied, this
A little solid particulate matters can cause serious influence to slurry oil deep processed product and upstream device, be unfavorable for the comprehensive utilization of slurry oil.

M solid particle.
(2) sedimentation separation method：Including natural sedimentation and chemical deposition method, natural sedimentation clean-up effect is not high, efficiency
Low, disengaging time length, equipment is huge, it is difficult to remove the particle that diameter is less than 20 μm.
(3) it is separated by filtration method：The solid catalyst particle in slurry oil is intercepted by using a kind of poromerics and reached
Purpose is separated, this method is simple to operate, but can not remove micron particles.
(4) electrostatic separation method：Separating effect is influenceed by factors such as slurry oil property, catalyst particle sizes, equipment
Complicated, investment is greatly.
(5) chemical assistant partition method：Promote catalyst granules conglomerate using emulsifying agent, flocculant so that most of
Flocculating setting is to reach the purpose of separation from slurry oil for catalyst granules, but this method uses chemical reagent, easily to pipe-line equipment
Cause to corrode, it is also possible to impact slurry oil property.
With the development of science and technology, the method for emerging many extract and separate purifications, supercritical liquid extraction technique are made
Show one's talent for the recent decades new development novel green chemical separation technology that gets up in numerous methods.Supercritical fluid has gas concurrently
The technological parameter such as the dissolution characteristics and mass transfer characteristic of body and liquid, pressure and temperature that can be by changing extraction process, selectivity
Ground comes out required component extracting.But because supercritical extraction technique is there is extracting pressure is high, extraction time length, especially
It is for catalytic cracked oil pulp, solid catalyst particle is contained in slurry oil, it is carried out using supercritical liquid extraction technique
Processing, extraction efficiency is than relatively low, so as to limit its application.
