    Abstract: The catalytic reactor with downward flow comprises a chamber (1) containing at least two solid catalyst beds (2; 11) separated by an intermediate zone comprising an essentially horizontal collecting plate (5) communicating with a vertical collecting pipe (7) for receiving fluids collected by the collecting plate, with a means for injecting a quenching fluid (8) emptying into the collecting pipe. An annular mixing chamber (9) is located below the collecting plate (5). A predistribution plate (11) is arranged below the chamber (9).The injection means (8) comprises a tubular portion that empties into the collecting pipe (7) in such a way as to inject quenching fluid in a direction forming an angle θ between 45° and 135° with the direction D from the axis of the mixing chamber measured at its input end.
