Title
(EN) A PROCESS FOR HYDROGENATING AROMATIC POLYMERS
(FR) PROCEDE D'HYDROGENATION DE POLYMERES AROMATIQUES
Abstract
(EN) The present invention is directed to a hydrogenation catalyst and a process for hydrogenating an aromatic polymer having a number average molecular weight (Mn) of from 40,000 to less than 120,000 comprising contacting the aromatic polymer with a hydrogenating agent in the presence of a silica supported metal hydrogenation catalyst, characterized in that the silica has a pore size distribution such that at least 95 percent of the pore volume is defined by pores having diameter from 300 to 1000 angstroms, less than 4 percent of the pore volume is defined by pores having a diameter of 200 angstroms or less and at least 80 percent aromatic hydrogenation is achieved.
(FR) L'invention porte sur un catalyseur d'hydrogénation et un procédé d'hydrogénation d'un polymère aromatique d'un poids moléculaire moyen (Mn) compris entre 40.000 et moins de 120.000, consistant à mettre en contact ledit polymère aromatique avec un agent hydrogénant en présence d'un catalyseur métallique d'hydrogénation sur un support de silice dont la distribution en taille des pores est telle qu'au moins 95 % du volume des pores est fait de pores d'un diamètre compris entre 300 et 1000 Å, et moins de 4 %, de pores d'un diamètre de 200 Å ou moins, ce qui permet d'obtenir au moins 80 % d'hydrogénation aromatique.
