A catalytic distillation structure (10) having a plurality of corrugated vertically disposed catalyst containing elements (12) separated by inert spacing elements (24) is disclosed. The catalyst containing elements (12) each have two layers of gas permeable material (18, 20), such as wire mesh, joined together at regularly spaced intervals (13) to form a single sheet (12) having pockets (22) disposed on the surface. A particulate catalyst (26) is disposed within the pockets (22). The catalyst (26) within the pockets (22) provides a reaction zone where catalytic reactions may occur and the gas permeable sheets (18, 22) provide mass transfer surfaces to effect a fractional distillation. The spacing elements (14) allow for a variation of the catalyst density and loading.
Structure pour distillation catalytique (10) comportant une pluralité d'éléments (12) verticaux alvéolés contenant le catalyseur, séparés par des entretoises inertes (24). Chacun des éléments (12) contenant le catalyseur comporte deux couches d'un matériau perméable au gaz (18, 20) tel que de la toile métallique reliées ensemble à intervalles réguliers (13) de façon à former une feuille unique (12) présentant à sa surface des poches (22) destinées à recevoir un catalyseur particulaire (26). Le catalyseur (26) présent dans les poches (22) constitue la zone de réaction catalytique tandis que les feuilles perméables au gaz (18, 20) constituent des surfaces de transfert de matière où s'opère la distillation fractionnée. Les entretoises (14) permettent de faire varier la densité et la charge du catalyseur.
