CA 2201590
A halogenated compound (I) containing one or more >C=O, olefinic and/or aromatic >C=C< groups is hydrogenated for producing a halogenated compound (II) having no or a decreased level of >C=O, olefinic and/or aromatic >C=C< groups. In the hydrogenation process a liquid feed stream comprising one or more of these compounds (I) is contacted with a hydrogen-rich gaseous stream and a liquid recycle stream comprising one or more of these compounds (II) in the presence of a catalyst.
Composé halogéné (I) contenant un ou plusieurs groupes ?C=O, oléfiniques et/ou ?C=C? aromatiques, qui est hydrogéné pour produire un composé halogéné (II) ne possédant pas ou seulement une quantité réduite de groupes ?C=O, oléfiniques et/ou ?C=C? aromatiques. Dans le processus d'hydrogénation, un flux de départ liquide comprenant un ou plusieurs des composés (I) est mis en contact avec un flux gazeux riche en hydrogène et un flux de recyclage liquide comprenant un ou plusieurs des composés (II), en présence d'un catalyseur.
