The invention involves a method for treatment of a charge comprising at least hydrocarbons containing at least three carbon atoms per molecule, including acetylenic and diolefinic hydrocarbons. The method entails the passage of the charge through a distillation zone linked to a hydrogenation reaction zone comprising at least one catalytic hydrogenation bed inside or outside the distillation zone, in which at least a portion of the acetylenic and diolefinic hydrocarbons contained in the charge is hydrogenated in the presence of a hydrogen-rich gas flow. This method is particularly relevant to the treatment of catalytic cracking products.
L'invention concerne un procédé de traitement d'une charge comprenant au moins des hydrocarbures contenant au moins 3 atomes de carbone par molécule, parmi lesquels des hydrocarbures acétyléniques et dioléfiniques, ledit procédé comprenant le passage de ladite charge dans une zone de distillation associée à une zone réactionnelle d'hydrogénation, comprenant au moins 1 lit catalytique d'hydrogénation intérieur ou extérieur à ladite zone de distillation, dans laquelle on réalise l'hydrogénation d'au moins une partie des hydrocarbures acétyléniques et dioléfiniques contenus dans ladite charge, en présence d'un flux gazeux riche en hydrogène. Ce procédé s'applique particulièrement au traitement de produits issus du craquage catalytique.
