14 ABSTRACT This invention refers to a converter for heterogeneous catalytic synthesis under pressure, consisting of an external shell in a single piece and inside this of at least a cartridge containing a catalyst arranged in one or more beds contained in catalyst-carrying baskets, characterized by the fact that the external wall of these baskets is provided with means that protrude from the closed bottom and are coupled, in order to be supported, with means protruding from the internal continuous face which extends substantially along the entire axial height of the converter and is the nearest to the internal wall of the baskets. For the reactions at higher pressures, the wall holding the protruding support rings at the bottom of the baskets is a cartridge wall in a single piece that extends substantially along the whole shell and forms with this an airspace. For the reactions at lower pressures, the support rings of the basket bottoms protrude from the internal surface of the shell. At least one of the catalytic beds supported by the baskets or elementary cartridges is centrally crossed by an indirect heat exchanger.
