Abstract

<PICT:0454806/III/1> <PICT:0454806/III/2> In apparatus for effecting catalytic reactions in the gaseous phase the catalyst is placed in conduits 6 formed by the juxtaposition of a smooth wall 1 and a wall 3 having longitudinal grooves. The gases before entering the reaction spaces circulate along the back of the grooved wall, and the smooth wall is subjected to the contact of a heating or cooling fluid. The smooth and grooved walls may be in the form of concentric cylinders as shown, or they may be flat.
