Patent ID: 8822363

Claim:
A process for regenerating a catalyst composition, wherein said catalyst composition comprises a molecular sieve and at least 10 wt. % coke having a C/H molar ratio in the range of 0.26 to 5, said process comprising: (a) contacting said catalyst composition with a first oxidative medium having oxygen and water in a reactor at first conditions sufficient to form a first regenerated catalyst composition having at least 50 wt. % less coke than said catalyst composition; and (b) monitoring the oxygen concentration at an exit of said reactor, and when said oxygen concentration drops below 10% of the oxygen concentration at said first conditions, then (c) contacting at least a portion of said first regenerated catalyst composition with a second oxidative medium having oxygen at second conditions sufficient to form a second regenerated catalyst composition having at least 50 wt. % less coke than said first regenerated catalyst composition, wherein said catalyst composition in step (a) and said first regenerated catalyst composition in step (b) have contacted a total amount of water in the range of 1 to 50 weight water per weight of said second regenerated catalyst composition.
