| description | This disclosure relates to a process for regenerating a catalyst composition, wherein the catalyst composition comprising a molecular sieve and at least 10 wt.% coke having a C/H ratio in the range of 0.26 to 5, the process comprising (a) contacting the catalyst composition with a first oxidative medium having oxygen and water at first conditions sufficient to form a first regenerated catalyst composition having at least 50 wt.% less coke than the catalyst composition; and then (b) contacting at least a portion of the first regenerated catalyst composition with a second oxidative medium having oxygen, and optionally water, at second conditions sufficient to form a second regenerated catalyst composition having at least 50 wt% less coke than the first regenerated catalyst composition, wherein the catalyst composition in step (a) and the first regenerated catalyst in step (b) have contacted total amount of water in the range of 1 to 50 weight water per weight of the second regenerated catalyst composition. |
