Abstract (en)
[origin: US7220351B1] An apparatus and a process for catalytic cracking of a hydrocarbon feed is described, carried out in at least two reaction zones, one ( 30 ) operating in catalyst riser mode, wherein the feed and catalyst from regeneration zone ( 3 ) are circulated from bottom to top, the first gases produced are separated from the coked catalyst in a first separation zone ( 38 ), the catalyst is stripped ( 40 ), a first cracking and stripping effluent ( 42 ) is recovered and the coked catalyst is recycled ( 45 ) to the regeneration zone. Catalyst ( 12 ) from regeneration zone ( 3 ) and a hydrocarbon feed ( 19 ) are introduced into the upper portion of a dropper reaction zone ( 16 ), the catalyst and feed being circulated from top to bottom, the coked catalyst is separated from the second gases produced in a second separation zone ( 20 ), the second gases ( 24 ) produced are recovered and the coked catalyst is recycled ( 25 ) to the regeneration zone.
