Abstract: A process and apparatus for catalytic conversion of feedstock and separating catalyst from product gas comprises a first hydrocarbon feedstock contacted with a first stream of catalyst in a first riser to produce a first mixture of catalyst and product gases. A second hydrocarbon feedstock is contacted with a second stream of catalyst in a second riser to produce a second mixture of catalyst and product gases. The first riser and/or the second riser may terminate within a reactor vessel. The first mixture of catalyst and product gases from the first riser pass into a first disengagement chamber within the reactor vessel. The second mixture of catalyst and product gases pass from the second riser into a second disengagement chamber within the same reactor vessel.

Abstract: Apparatuses and methods for cooling catalyst are provided. In one embodiment, an apparatus for cooling catalyst includes a catalyst cooler vessel having a catalyst inlet for receiving catalyst. The apparatus includes a gas distributor lance positioned in the catalyst cooler vessel and having a gas outlet configured for injecting gas into the catalyst. The apparatus also includes a heat exchange tube positioned in the catalyst cooler vessel and having an outer surface. The heat exchange tube is configured to transfer heat from the catalyst to a heat exchange fluid. The apparatus further includes a hard surfacing material located on the outer surface of the heat exchange tube.
