The invention relates to a method for hydrogenating aromatic polymers in the presence of catalysts and in the presence of a hydrocarbon which contains oxygen, whereby, as a catalyst, a metal or a mixture of metals of subgroup VIII of the periodic table is charged together with a supporting material comprised of silicon dioxide, aluminum dioxide or a mixture thereof.
L'invention concerne un procédé d'hydrogénation de polymères aromatiques en présence de catalyseurs et en présence d'un hydrocarbure contenant de l'oxygène. Comme catalyseur, on utilise un métal ou un mélange de métaux du groupe secondaire VIII de la classification périodique des éléments, avec un support de dioxyde de silicium, d'oxyde d'aluminium ou constitué d'un mélange de ceux-ci.
