CA 2514456

A reactor configuration especially suitable for interphase mass transfer and mixing of multiple phases, i.e. gas(es), liquid(s), and solid(s) where reaction is catalyzed by a solid catalyst comprises a draft tube reactor wherein the solid catalyst particles are maintained in an annular space (25) between the draft tube (21) of the reactor and an annulus-defining wall by means of filter elements (26, 27) positioned downstream and optionally also upstream from the catalyst bed.

L'invention concerne un ensemble réacteur particulièrement adapté au transfert de masse entre phases et au mélange de plusieurs phases, soit gaz, liquide(s) et solide(s), la réaction étant catalysée par un catalyseur solide. Cet ensemble comprend un réacteur à tube de circulation, les particules du catalyseur solide étant maintenues dans un espace annulaire (25) entre le tube de circulation (21) du réacteur et une paroi annulaire au moyen d'éléments filtrants (26, 27) disposés en aval et, éventuellement, en amont du lit catalytique.
