Abstract

Described here is a system (8; 9; 50) of walls for catalytic beds of reactors (1) for the heterogeneous synthesis of chemical compounds characterized in that it comprises a wall (14) of predetermined thickness in direct contact with a catalytic bed (7) for containing it, said wall having a plurality of portions (17) permeable to gases and a plurality of portions (19; 54; 55) impermeable to gases, said portions (17) permeable to gases each being equipped with a plurality of slits (18; 52, 53; 60; 70) of a size such as to allow the free passage of the synthesis gases through them but not the passage of the catalyst.
