Abstract
Device for holding a granular catalyst suitable for use in the decontamination of exhaust gas from an internal combustion engine. The device comprises a housing which is closed by means of end plates and provided with a gas inlet and gas outlet and in which there is disposed a sleeve having perforated walls which are substantially circular in cross-section, this sleeve being disposed therein substantially concentrically with respect to the gas inlet. The device is provided with one or more flow-defining means which are accommodated in the housing, the gas flow-defining means causing gas admitted to the housing to be at least partially directed in a substantially axial direction so as to form a stream flowing under increased static pressure towards one of the end regions of the sleeve.
