Abstract
A system for treatment of one or more flowing materials includes a support bed (32) comprising a plurality of support elements (34). The support bed may have a void fraction of at least 45%. An active bed (36), such as a bed of catalytic elements, may be supported by the support bed. The void fraction of the support bed may be larger than that of an equivalent bed of conventional, spherical elements, enabling significant improvements in the flow rate of reactants through the bed and/or a reduced pressure drop across the support bed.
Claims21
A system for treatment of one or more flowing materials comprising:
- a shell;
- a support bed in the shell comprising a plurality of support elements, the support bed having a void fraction of at least 50%;
- an active bed in the shell supported by the support bed;
- and
- wherein the support bed has an activity towards the one or more flowing materials which is less than 20% of that of the active bed on a basis of weight.
A system for treatment of one or more flowing materials comprising:
- a support bed comprising a plurality of non-spherical support elements, the support elements each defining at least one through passage, said support bed having a void fraction of at least 45%;
- and
- a bed comprising a plurality of active elements supported by the support bed, the support elements having an activity per unit weight towards the flowing materials which is no greater than 20% of the activity per unit weight of a majority of the active elements in the bed of active elements.
