A displacement gas is introduced below the continuous reforming reactor for this purpose

As shown in the image in the title, I would like to know why a purge gas needs to be introduced below the continuous reforming reactor
Blow off the oil and gas carried by the catalyst
Are there any hazards to using a catalyst to carry oil and gas for regeneration?
Oil and gas enter the raw oil lift pipeline where they condense. The lift pipeline is blocked, affecting the lifting of the catalyst.
It’s better to read more books! The answers are in the book!
When oil and gas enter the oxygen-rich environment of regeneration and coking, a large amount of heat is released, which damages the catalyst, leads to metal accumulation, and causes damage to the carrier
Prevent high-temperature oil and gas from entering the lifters and lift pipes and condensing, thereby avoiding interference with the lifting of the catalyst.
It also serves a cooling function, ensuring that the temperature of the catalyst entering the lift pipe does not exceed the operating temperature suitable for carbon steel
