Abstract
A baffle is installed on the wall of a regenerator vessel to push catalyst away from the wall to ensure adequate exposure to regeneration gas and complete combustion of coke from the catalyst. We have found that in deep beds, catalyst can flow down the walls and escape sufficient exposure to regeneration gas and undergo too little regeneration.
Claims20
A process for combusting coke from catalyst comprising:
- delivering coked catalyst to a regenerator vessel;
- delivering regeneration gas to said regenerator vessel for combusting coke from said catalyst to produce flue gas and regenerated catalyst;
- pushing catalyst away from a wall of the regenerator vessel;
- separating said flue gas from said regenerated catalyst;
- discharging regenerated catalyst from said regenerator vessel;
- and
- discharging flue gas from said regenerator vessel.

A catalyst regenerator vessel for combusting coke from catalyst comprising:
- a wall of said regenerator vessel;
- a catalyst inlet for feeding catalyst to said vessel;
- a distributor for distributing regeneration gas to said vessel;
- a baffle on said wall for pushing catalyst away from said wall;
- a separator in communication with said regenerator vessel for separating gas from said catalyst;
- a flue gas outlet for discharging flue gas from said vessel;
- and
- a regenerated catalyst outlet for discharging regenerated catalyst from said vessel.
