Description
Technical field
The present invention relates to grading plant technical field, particularly relate to a kind of reforming catalyst negative pressure fluidised form wind-transformation vehicle type physics
Grading plant.
Background technology
Continuous reformer is the device for the purpose of producing high-octane gasoline blending component and aromatic hydrocarbons.Its reaction exists
Carry out equipped with in the mobile bed radial reactor of catalyst made from platonic, during plant running, both can add in reactor
Add catalyst, it is also possible to from reactor, draw off catalyst.
Nearest period plant running within about 3 years, be one cycle, therebetween due to upstream raw material factor and behaviour in running
Factor of making has local run aways phenomenon to form dwarf's ball, owing to dwarf's the biggest catalyst of ball intensity produces mill in cyclic process sometimes
Damage, have partial catalyst wear and tear in cyclic process in the course of time and diminish, this part diminish catalyst be easy for blocking Johnson
Net and not circular regeneration, carbon deposition quantity of catalyst of long duration the most constantly rises and ultimately forms Johnson's selvage temperature runaway tympanites modification
(often occur in and bottom four anticentre pipes, heave horizontal strength fracture race agent phenomenon).
Catalyst the most constantly circulates, and makes the surfaces externally and internally of catalyst can produce knot carbon.Device is in general feelings
Under condition, the highest control of carbon deposition quantity can circular regeneration below 6%.
In catalyst recycle process, having partial catalyst that circulation is not fully achieved, the catalyst that this part does not flow claims
For " dead band catalyst ", for several times after circulation, the carbon deposition quantity of dead band catalyst may be up to 20～50%, when unloading catalyst, dead band
Catalyst can be entrained in low C catalyst outside outflow device, so forms catalyst contamination, and quantity depends on the scale of device, sets
The operating procedure that meter and catalyst draw off is relevant, and pollution rate reduces many, typically 5%～about 35%.
Existing experience have shown that, if in catalyst containing about 3% high C catalyst (phosphorus content > 8%), this catalyst
Should not use again, dead band agent or to accompany the agent of part dead band for the damage of equipment be during regenerator is turned " burning in vain " by " black burning "
Occur.Under " black burning " operating mode, the oxygen distribution of regenerator is: scorch region oxygen content is 0.5～1.3%, and oxychlorination district oxygen content is
0%；Under " in vain burn " operating mode, the oxygen distribution of regenerator is: scorch region oxygen content is 0.5～1.3%, oxychlorination district oxygen content be 4～
20%.The dead band catalyst of graphitization burns slowly under the environment of scorch region, " black burning ", after turning " burning in vain ", dead band agent is by burning
When Jiao Qu enters oxychlorination district, can burn rapidly under oxygen environment at 510 DEG C of high temperature, 4～20%, produce high temperature, sometimes temperature
Up to more than 1100 DEG C, the fusing of regenerator internals can be made, make sintering of catalyst.
Reformer unload during agent by dead band catalyst contamination catalyst medium high carbon catalyst total mass fraction about 5%～
35%, wherein 95～65% is the catalyst that can be continuing with.Therefore dress can not directly be returned, it is necessary to use windmill type classification skill
The catalyst that can return dress use is branched away by art, and in population in Zhenhai Refine-Chemical Company, five four reforming technique grading effects reach more than 98%.
At present, the shortcoming that the pellet type catalyst vibrating fluidized bed density classification technology of domestic use exists has (1) classification to imitate
Fruit is the highest；(2) there is abrasion that (3) in the classification process catalyst easy moisture absorption is lost；(4) density contrast catalyst below 3% can not divide
Level.
