Abstract:
1. A reaction device comprising a catalytic reactor of elongated shape along an essentially vertical axis, said reactor comprising several vertically-staged catalytic reaction zones of similar diameters, said reactor being suitable for the circulation of at least one moving-bed granular catalyst that descends successively into each of the reaction zones and comprises means ( 100 ) for introducing and means ( 101 ) for evacuating a reaction fluid, means ( 102 ) for introducing fresh or regenerated catalyst at the top of the reactor, and means ( 105 ) for evacuating spent catalyst from a lower part of the reactor, said reactor comprising: a) an upper reaction zone ( b) means ( c) means ( d) means ( e) conduit ( f) means for passing the catalyst mixture thus produced in said means for mixing to the reaction zone (
