Abstract
A catalytic cracking apparatus comprises a catalyst lift pot having a first diameter, a riser-reactor having a mouth connected to the lift pot and defining a second diameter which is smaller than the first diameter, and a plug member which axially extends into the lift pot from the lower end thereof. The riser-reactor and plug member are situated so that fluid flowing through the lift pot before flowing into the riser-reactor flows radially inward across an upper end surface of the plug member. The apparatus further comprises a device for introducing a fluidizable catalyst through a sidewall of the lift pot, and a device for releasing liquid oil feedstock and atomizing fluid into the lift pot from the upper end surface of the plug member.
