TITLE CONVERTER FOR HETEROGENEOUS SYNTHESIS MORE PARTICULARLY FOR AMMONIA, METHANOL AND HIGHER ALCOHOLS APPLICANT Ammonia Casale S.A. INVENTOR Umberto ZARDI ABSTRACT A converter for heterogeneous synthesis. The converter contains a variable number of internal cartridges, each having a non-perforated external wall which forms an interspace with an internal shell wall. The converter also has a corresponding variable number of catalytic beds, each having granular catalyst. The catalyst beds are contained in a vessel having a closed bottom, an open top, and two cylindrical concentric perforated walls. The perforated walls allow for adduction and extraction of reaction gases which flow axially and radially through the catalyst beds. Heat exchangers are orientated on the same axis with the annular catalyst beds and consist of tube-bundles within a shell. Reaction gas feed tubes extend through some of the heat exchanger tube bundles.
