Abstract
A fluid catalytic cracking unit of the type having a reactor vessel positioned directly over a regenerator vessel. A pair of catalyst wells are mounted on the lower interior portion of the regenerator vessel and are each in communication with an associated conduit. The other end of each conduit is connected to an atomizing lift pot positioned beneath the lowest level of the regenerator vessel. The atomizing lift pot is placed in fluid communication with the reactor vessel via a riser reactor which may be either internal or external to the regenerator vessel. Plug valves or slide valves may be used to control the flow of regenerated catalyst from the regenerator to the lift pot.
