Description
Technical field
The present invention relates to sedimentation agent technical field, be specifically related to a kind of catalytic cracked oil pulp sedimentation agent and preparation method thereof,
Application.
Background technology
Catalytic cracking (FCC) slurry oil is the heavy product at the bottom of FCC apparatus main fractionating tower tower, is to be 343-593 DEG C by boiling point
No conversion hydrocarbon compounds composition, it is in addition to containing silica-alumina catalyst fine powder, possibly together with substantial amounts of condensed-nuclei aromatics.FCC slurry
There is good economic worth, its can 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 due to FCC slurry contain 2000～9000ppm catalyst solid powder and make its economic scale and
Increment utilization is very limited.Substantially effectively to utilize FCC slurry, it is necessary to the catalyst solid powder in removing slurry oil.
The technology of existing Removal of catalyst pressed powder includes: natural sedimentation, auxiliary agent sedimentation, Filtration, electrostatic divide
From method and centrifugal separation etc..Natural sedimentation is the method used the earliest, only by gravitational settling, but due to catalyst fines
Granule tiny (diameter is between 1～80 μm), the viscosity of slurry oil and proportion are the biggest, the existence of electric double layer in addition, so effect
Rate is low, the cycle is long, it is difficult to industrially large-scale application.Electrostatic separation rule can due to processing procedure will necessarily occur certain
Phenomenon that a little parts surfaces are wrapped up by oil and ideal effect can not be reached.Centrifugal separation processes large batch of slurry oil because of very difficult,
So the not value of commercial Application and example.Filtration is the highest to the requirement of equipment, and Sinopec petrochemical industry science is ground
Study carefully institute's layer and use metal micro-holes Filtration separating FCC slurry repeatedly, but microporous pipe easily to block the use cycle short, it is difficult to industry should
With.Chemical settling agent method is the cost-effective method of one that development in recent years is got up, it is possible to significantly improve catalyst fines
Sedimentation velocity and removing speed.Chinese patent CN1297981A discloses a kind of catalyst powder in catalytic cracking oil slurry that removes
Method, be in catalytic cracked oil pulp add 0.05～2.0 weight the amines of %, fats, silicone oil, sulphonic acids Sulfonates it
In one or more flocculant mix homogeneously after, flocculating sedimentation 16～48 hours at 80～100 DEG C, isolate
Layer clear liquid, lower floor's flocculation liquid centrifugation 5～after 20 minutes at 80～100 DEG C, obtain centrifugal clear liquid, above two clear liquid is made
For clarified oil product.This patent claims can be by solid content in slurry oil except to below 50ppm, the clarified oil after Removal of catalyst powder be received
Rate reaches 98 weight more than %.Chinese patent CN01113133.0 uses the surfactant adding 100-1000ppm in FCC slurry
Compounds settling aids, uniformly mixes, and keeps slurry oil temperature 50-120 DEG C natural subsidence 12-60 hour in settling tank, from
And the catalyst fines removal efficiency increased may be up to 70-90%.But the problem of above technology mostly sedimentation time length, thus increase
The build the side of settling tank and expense, industrial more difficult enforcement.
