<p>A device for use in the catalysis of a chemical reaction has a container (1) with a fluid inlet (5) thereto and a fluid outlet (6) therefrom and a substantial number of catalyst bodies (8) assembled therein. The catalyst bodies (8) are packed in the container (1) in a pre-determined orientation comprising one or more trains (7) thereof occupying the cross-section of the container (1). In order to reduce resistance to flow of reactants through the device, each of the catalyst bodies (8) has a plurality of internal channels of an ordered, pre-determined size and arrangement for permitting substantially unrestricted flow of reactants therethrough. Also, the or each train (7) is aligned with the general direction of flow of reactants through the device to define pathways for reactants to pass therethrough in this general direction. The catalyst bodies (8) each carry catalytically active material for the reaction.</p> |
