A method and an apparatus for performing a continuous reaction with at least one liquid reaction phase incorporating at least one starting compound in the presence of at least one solid-phase catalyst, wherein the phases to be contacted are circulated through at least one pulsed reaction column (1), the liquid reaction phase is continuously fed into the middle or lower portion of the pulsed column (1), the liquid phase is circulated upwards through the pulsed column (1), and a counterflow made up of lumps (9) of a solid selective extraction compound is continuously circulated. Furthermore, each solid catalyst is continuously circulated through the pulsed column (1) in contact with the liquid phase.
L'invention concerne un procédé et une installation pour effectuer une réaction en continu avec au moins une phase liquide de réaction incorporant au moins un composé de départ en présence d'au moins un catalyseur en phase solide, caractérisés en combinaison en ce que l'on fait circuler les phases à mettre en contact dans au moins une colonne pulsée (1) de réaction, et en ce que l'on introduit en continu la phase liquide de réaction en partie médiane ou inférieure de la colonne pulsée (1), on fait circuler la phase liquide de bas en haut dans la colonne pulsée (1), et on fait circuler en continu à contre-courant des morceaux (9) de composé solide d'extraction sélective. On fait en outre circuler en continu chaque catalyseur solide dans la colonne pulsée (1) au contact de la phase liquide.
