Abstract

L'invention concerne un procédé pour effectuer des réactions entre un gaz et un liquide dans un réacteur à écoulement. On injecte un gaz sous la forme de bulles ayant un diamètre compris entre 0,1 et 4 mm dans un liquide qui s'écoule vers le bas à une vitesse de 0,2 à 0,5 mm/s. Le rapport du volume de liquide au volume du gaz doit être supérieur à 8 : 1 et le temps de séjour du gaz doit être d'au moins 6 secondes par mètre de longueur du reacteur. On peut ainsi atteindre, en un seul passage, le degré de réaction voulu.
