Title (EN) PROCESS FOR SELECTIVE HYDROGENATION OF AN OLEFINIC FEED STREAM CONTAINING ACETYLENIC AND DIOLEFINIC IMPURITIES
(FR) PROCEDE D'HYDROGENISATION SELECTIVE D'UN COURANT D'ALIMENTATION OLEFINIQUE CONTENANT DES IMPURETES ACETYLENIQUES ET DIOLEFINIQUES
Abstract: front page image
(EN)A process for selective hydrogenation of a C¿2? and C¿3? olefinic feed stream containing acetylenic and diolefinic impurities whereby the acetylenes and diolefins impurities are selectively hydrogenated concurrently in a vapor phase process without first separating the C¿2? and C¿3? olefinic gases into separate feed stream.
(FR)La présente invention concerne un procédé d'hydrogénisation sélective d'un courant d'alimentation oléfinique C¿2? et C¿3? contenant des impuretés acétyléniques et dioléfiniques qui permet d'hydrogéniser sélectivement et simultanément les impuretés acétylènes et dioléfines dans un processus en phase vapeur sans séparation préalable des gaz oléfiniques C¿2? et C¿3? en un courant d'alimentation séparé.
