Liquid petroleum or chemical streams are upgraded by passing the stream countercurrent to the flow of a treat gas such as a hydrogen-containing gas in at least one reaction zone (r1, r2, r3). The reaction vessel (R) used in the practice of the present invention contains vapor passageway means (VB1, VB2, VB3, VB4, VB5) and optionally liquid passageway means (LD) to bypass one or more catalyst beds. This permits more stable and efficient reaction vessel operation.
Des flux de produits chimiques ou de produits de pétrole liquides sont valorisés lorsqu'on fait passer le flux à contre courant du flux d'un gaz de traitement, par ex. un gaz contenant de l'hydrogène, dans au moins une zone d'interaction (r1, r2 ou r3). La cuve à réaction (R) utilisée dans le cadre de la présente invention contient des passages (VB1, VB2, VB3, VB4, VB5) pour la vapeur, et éventuellement des passages (LD) pour un liquide, permettant de contourner au moins un lit catalytique, et donc d'accroître la stabilité et l'efficacité de fonctionnement de ladite cuve.
