The method may further include passing the decoked catalyst to a combustor and combusting a supplemental fuel in the combustor to heat the decoked catalyst and produce a heated catalyst, passing the heated catalyst to an oxygen soak zone and contacting the heated catalyst with a second oxygen-containing gas to produce a reactivated catalyst, and passing the reactivated catalyst to the reactor."
