[0016] Such as figure 1 As shown, the hydrocarbon feedstock from the bottom line 19 and the catalyst particles from the catalyst outlet pipe 16 are in contact with the riser 1, and the pre-lift steam enters the riser 1 from the gas line 18.
[0017] The top of the riser 1 is connected to the settler 2. In the settler 2, separation of the conversion products and stripping of the deactivated catalyst are performed. The treated raw materials are separated in the cyclone 3 at the top of the settler 2, and the separated conversion stream exits the settler 2 from the outlet line 4, and at the same time the deactivated catalyst flows downward by gravity into the bottom of the settler 2. Carry out general deactivated catalyst stripping. The deactivated catalyst after the stripping flows out from the bottom of the settler 2 and passes through the conveying pipe 5 to the regenerator 8. The conveying pipe 5 is provided with a control valve 6. In the regenerator 8, the coke deposited on the ...
