Description
Technical field
A kind of petroleum catalytic cracking raw material adding set of the present invention, when being related to a kind of petroleum catalytic cracking, addition oil is former
The device of material, belong to PETROLEUM PROCESSING field.It is more particularly to a kind of to place whipping by being concentrated to catalyst, inject petroleum
When the very first time and catalyst contact raw material adding set.
Background technology
At present, oil is used as the acquisition raw material of fuel oil as a kind of natural energy resources, is used by a large amount of exploitations, is produced in chemical industry
By the raw material as solution, chemical fertilizer and plastics etc., the natural oil for exploiting to obtain usually requires to be refined a variety of to obtain industry
Separation product, realization make full use of, and cracking catalysis are one of significant process of petroleum refining, and raw material is made in the presence of catalyst
It is transformed into the products such as cracked gas, gasoline and diesel oil, usual raw material uses the heavy distillate obtained by crude distillation, and heavy evaporates
Point oil viscosity it is generally larger, existing frequently-used petroleum catalytic cracking method is that catalyst is put into reaction vessel, by original
Material is added directly into reaction vessel with catalyst haptoreaction, because the viscosity of raw material is larger, is gathered in around catalyst
Heavy end oil mobility is relatively low, and catalytic reaction is concentrated on around catalyst, and catalytic reaction is less efficient, in order to strengthen raw material
Mobility, typically now raw material is stirred using agitating device, catalyst rocks in reaction vessel with raw material, to follow-up
The recovery of catalyst impacts, existing frequently-used oil catalytic cracking unit, as publication number CN103725321A discloses one
Material is sent into riser with urging by the petroleum hydrocarbon catalytic cracking process and its device of kind high output of ethylene and/or propylene, the device
Agent carries out catalytic cracking reaction, and catalyst is immersed in petroleum, the raw material that new addition enters can not the very first time with urging
Agent haptoreaction, could carry out contact catalysis after agitation, and catalyst is flowed freely with raw material in reaction unit, subsequently urged
The collection of agent is more troublesome, and catalyst speed of related movement in reaction unit is slower, and raw material is anti-in whole reaction unit
Answer speed slower, it is less efficient.
