    摘要: 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.
