Description
Technical field
The present invention relates to sedimentation agent technical fields, and in particular to a kind of catalytic cracked oil pulp sedimentation agent and preparation method thereof,
Using.
Background technique
Catalytic cracking (FCC) slurry oil is the heavy product of FCC apparatus main fractionating tower tower bottom, be by boiling point be 343-593 DEG C
Unconverted hydrocarbon compound composition, it is except also containing a large amount of condensed-nuclei aromatics containing in addition to silica-alumina catalyst fine powder.FCC slurry
With good economic value, can be used as the raw material of carbon black oil, needle coke and rubber filling oil, be alternatively arranged as being hydrocracked and
The raw material of FCC, but made due to catalyst solid powder that FCC slurry contains 2000~9000ppm its economic scale and
Increment is utilized and is very limited.Substantially effectively to utilize FCC slurry, it is necessary to remove the catalyst solid powder in slurry oil.
The technology of existing Removal of catalyst solid powder includes: natural sedimentation, auxiliary agent sedimentation, filtration method, electrostatic point
From method and centrifugal separation etc..Natural sedimentation is the method used earliest, only leans on gravitational settling, but due to catalyst fines
Particle it is tiny (diameter is between 1~80 μm), the viscosity and specific gravity of slurry oil are all larger, in addition the presence of electric double layer, thus effect
Rate is low, the period is long, it is difficult to industrially large-scale application.Electrostatic separation rule can due to will necessarily occur in treatment process certain
A little parts surfaces cannot be reached ideal effect the phenomenon that oil package.Centrifugal separation handles large batch of slurry oil because being difficult,
So there is no the values and example of industrial application.Requirement of the filtration method to equipment is very high, and Sinopec petrochemical industry science is ground
Institute's layer is studied carefully using metal micro-holes filtration method separating FCC slurry repeatedly, but easily to block service life short for microporous pipe, it is difficult to which industry is answered
With.Chemical settling agent method is a kind of cost-effective method developed in recent years, can significantly improve catalyst fines
Sinking speed and removing speed.Chinese patent CN1297981A discloses a kind of removing catalyst powder in catalytic cracking oil slurry
Method, be added in catalytic cracked oil pulp 0.05~2.0 weight amine of %, fats, silicone oil, sulphonic acids Sulfonates it
One of or more than one flocculant after mixing, flocculating setting 16~48 hours, are isolated at 80~100 DEG C
Layer clear liquid, lower layer's flocculation liquid be centrifugated 5 at 80~100 DEG C~after twenty minutes, obtain centrifugal clear liquid, above two clear liquid work
To clarify oil product.The patent claims to remove solid content in slurry oil to 50ppm hereinafter, the clarified oil after Removal of catalyst powder is received
Rate weighs % or more up to 98.Chinese patent CN01113133.0 is using the surfactant that 100-1000ppm is added into FCC slurry
Class compound settling aids uniformly mix, and keep 50-120 DEG C of slurry oil temperature natural subsidence 12-60 hours in settling tank, from
And increased catalyst fines removal efficiency may be up to 70-90%.But the problem that the above technology mostly sedimentation time is long, to increase
The build the side and expense of settling tank, industrially more difficult implementation.
