    摘要： An apparatus for mixing regenerated and carbonized catalyst involves obstructing upward flow of catalyst by one or more baffles between a catalyst inlet and a feed distributor. Each catalyst stream may be passed to opposite sides of a riser. Baffles obstruct upward flow to effect mixing of regenerated and carbonized catalyst to obtain a more uniform temperature and catalyst mixture before contacting the feed.

    摘要： Disclosed is a process for disengaging regenerated catalyst from flue gas in a catalyst regenerator so as to avoid re-entrainment of catalyst that has settled into a bed in the catalyst regenerator using a disengaging device. A disengaging arm of the disengaging device has an outer shell that encloses the arm, an inner shell with a slot for allowing catalyst and flue gas to exit the arm and an outer baffle having a lower edge located below the opening in the outer wall. The baffle directs the catalyst and flue gas downwardly and limits radial flow. Catalyst and flue gas enter the disengaging arm through an opening in an outer wall of a riser section at a first superficial velocity and exits through a slot in a bottom of the disengaging arm at no more than 1.33 the first superficial velocity.
