Abstract
The present application discloses a molecular sieve-based catalyst modification apparatus. The apparatus comprises a feed unit, a modification unitand a cooling unitconnected in sequence; the feed unit comprises a catalyst feed unitand a modifier feed unit, a catalyst and a modifier are introduced into the modification unitrespectively by the catalyst feed unit and the modifier feed unit and are discharged from the modification unit after sufficient reaction in modification unit, and then enter the cooling unitfor cooling. The present application further discloses a use method for the molecular sieve-based catalyst modification apparatus. The use method comprises: introducing a catalyst and a modifier into the modification unitrespectively through the feed unit; wherein the catalyst is modified by the modifier in the modification unit, and then discharged to the cooling unitto cool until the temperature is lower than 50° C., and then the cooled modified catalyst is transferred to any storage device.
