CA 2243851

A column (410) having a region for reaction with distillation of fluid streams is provided with structures (428) including catalyst-filled containers (432) having liquid permeable upper surfaces (440) which allow for the accumulation and flow of liquid form a liquid stream. The containers (432) include catalyst beds (434) positioned beneath the upper surface (440) of the containers. A portion of the liquid on the containers is driven through the catalyst bed by the liquid head created by the accumulated liquid and is catalytically reacted. Another portion of the liquid may be directed through a downcomer (444) which allows the accumulated liquid to leave the container without passing through the catalyst bed so that higher volumetric flow rates can be achieved.

Une colonne (410) présentant une région pour la réaction avec distillation de courants de fluide, est dotée de structures (428) comprenant des récipients (432) chargés de catalyseur et présentant des surfaces supérieures perméables (440) qui permettent l'accumulation et l'écoulement de liquide provenant d'un courant de liquide. Les récipients (432) contiennent des lits catalytiques (434) placés au-dessous de la surface supérieure (440) de ceux-ci. Une partie du liquide sur les récipients est acheminée à travers le lit catalytique par la charge hydrostatique créée par le liquide accumulé et subit une réaction catalytique. Une autre partie du liquide peut être envoyée par un tube de retour (44) qui permet au liquide accumulé de sortir du récipient sans passer à travers le lit catalytique de sorte que des débits volumétriques plus élevés puissent être atteints.
