Abstract

The apparatus for the continuous catalytic removal of binder from metallic and/or ceramic shaped bodies produced by powder injection molding, which comprises a binder removal furnace through which the shaped bodies pass in a transport direction and are brought to a suitable process temperature, a feed facility for introduction of a process gas which is required for binder removal and comprises a reactant, at least one facility for the introduction of a protective gas into a reaction space of the binder removal furnace and a flare to burn the gaseous reaction products obtained in binder removal, wherein one or more devices which lead to a flow of the process gas directed transversely to the transport direction in the apparatus are present.
