Abstract
One exemplary embodiment can be a process for mixing catalyst in a regenerator. The process can include providing a first stream of catalyst, a second stream of catalyst mixed with the first stream of catalyst, and an oxygen-containing gas to a chamber via a distributor of the regenerator. Generally, the chamber imparts a swirl to at least one of the oxygen-containing gas, the first catalyst, and the second catalyst for regenerating the catalyst.
Claims14
A regenerator for regenerating catalyst, comprising:
- A) a base;
- wherein the base comprises:
- 1) at least one wall;
- 2) a first conduit for transporting catalyst;
- and
- 3) a second conduit for transporting catalyst;
- B) a gas distributor proximate to a bottom of the base;
- and
- C) a chamber positioned over the gas distributor and spaced apart from the at least one wall;
- wherein the chamber forms at least one outlet and terminates in a cap for imparting a swirl to a gas rising therefrom.
