CA 2408189

A process for purifying an olefin feed comprising a content of phosphorus- containing impurities, said process comprising contacting said olefin feed with a sorbent selected from the group consisting of an acidic ion exchange resin, an acidic zeolite, an acidic alumina, a neutral alumina and an activated carbon, under conditions and for a time effective to reduce said content of phosphorus-containing impurities and to produce a purified olefin feed.

L'invention concerne un procédé de purification d'une charge oléfinique qui présente des impuretés contenant du phosphore. Ledit procédé consiste à mettre en contact ladite charge oléfinique avec un sorbant sélectionné dans le groupe constitué par une résine échangeuse d'ions de l'acide, une zéolite acide, une alumine acide, une alumine neutre et un carbone activé. Ce procédé est mis en oeuvre sous des conditions et pendant une durée qui permettent de diminuer la teneur en impuretés contenant du phosphore et de produire une charge oléfinique purifiée.
