Abstract
The energy consumption of conventional reactors for heterogeneous synthesis, e.g., ammonia synthesis and methanol synthesis, wherein the synthesis gas flows substantially axially through catalyst beds, is substantially reduced by inserting in at least one catalyst bed: two concentric cylindrical substantially perforated walls to laterally delimit the bed; a bottom closure between these walls; and optionally a diaphragm on top of the bed. Optionally also, a catalyst granulometry gradient may be employed in the upper part of the bed. An upper minor portion of at least one of the cylindrical walls may be unperforated. The synthesis gas now traverses the bed substantially radially.
