Abstract

Cette invention a trait à un procédé permettant d'améliorer le fonctionnement d'un processus de conversion d'alcynes portant de 2 à 6 atomes de carbone (de l'acétylène, de préférence) contenus dans un fluide contenant un hydrocarbure au moyen d'hydrogène pour produire les alcènes correspondants. Avant que des améliorations n'y aient été apportées, ce processus utilisait un certain volume de catalyseur d'hydrogénation nécessaire pour assurer la conversion des alcynes portant de 2 à 6 atomes de carbone en produit converti contenant moins d'alcynes que le fluide contenant un hydrocarbure. Les améliorations apportées consistent à mettre en contact, dans une zone de réaction adiabatique à un seul étage, dans des conditions de réaction, le fluide contenant un hydrocarbure renfermant des alcynes portant de 2 à 6 atomes de carbone (de l'acétylène, de préférence) avec un catalyseur contenant du palladium, de l'argent et un composé à base de fluorure de métal alcalin, sous un volume de conversion approprié inférieur au volume de catalyseur d'hydrogénation.
