Abstract

L'invention concerne un procédé d'injection de gaz dans un liquide et d'inhibition de la démixtion du gaz n'ayant pas réagi et du liquide dans un réacteur à circulation. Selon l'invention, le gaz est injecté dans le liquide par un ou plusieurs jets de liquide dirigés de haut en bas, qui sortent par un ou plusieurs injecteurs à la partie supérieure du tube de circulation, et est entraîné vers le bas par un courant de gaz et de liquide circulant dans ledit tube de circulation, s'élève dans un espace annulaire et - dans la mesure où il n'a pas réagi est entraîné en grande majorité à nouveau vers le bas en passant par dessus le bord supérieur du tube de circulation.
