A multi-bed catalytic converter comprising: a plurality of catalytic beds which are traversed in series by a process gas, sequentially from a first catalytic bed to a last catalytic bed of said plurality, and at least one inter-bed heat exchanger (7) positioned between a first catalytic bed and a second catalytic bed of said plurality, wherein at least the last catalytic bed of said plurality is adiabatic and is made of fine catalyst with a particle size not greater than 2 mm.

A reactor for hydrocarbon production that separates wax reaction products from lightweight gaseous reaction products. The reactor has a housing, a catalyst bed, a product recovery zone, and a stripping zone. The catalyst bed can be provided in multi-tubular and other fixed bed configurations. The stripping zone receives light-weight gas reaction products from the product recovery zone, while a gas outlet of the housing receives non-lightweight gaseous hydrocarbon reaction products from the product recovery zone. A wax outlet of the housing receives wax products from the product recovery zone.

In a cooled axial/radial flow converter, in which process gas passes from an outer annulus via a catalyst bed to an inner center tube, the catalyst bed is divided into identical modules stacked on top of each other. The process gas reaches the catalyst through openings facing the outer annulus, passes axially down the catalyst bed of each module, leaves the module through collectors in the bottom thereof, and flows to the center tube. The catalyst bed is cooled by cooling panels, in which the process gas is pre-heated to the reaction temperature, while at the same time the heat of reaction is partly removed from the catalyst bed. The converter is especially suitable as ammonia converter.
