PROCESS AND APPARATUS FOR REGENERATING CATALYST

Abstract: a catalyst regenerator vessel and a process for combusting carbonaceous deposits from catalyst is disclosed. the catalyst regenerator vessel comprises a combustion gas distributor in fluid communication with a combustion gas line for introducing a combustion gas to the vessel, a catalyst pipe, and a catalyst distributor in fluid communication with the catalyst pipe. the catalyst distributor comprises a header and a nozzle, the header and the nozzle are in fluid communication with the catalyst pipe for distributing coked catalyst to the vessel. the header comprises a header and a plurality of nozzles including an angular nozzle projecting at an angle to a longitudinal axis of the header. the process comprises delivering coked catalyst from a catalyst pipe to the catalyst distributor wherein the catalyst distributor discharges the coked catalyst from at least two sides of the catalyst pipe into the regenerator vessel.
