CA 2228946

Catalyst comprising from 0.1 to 15 % by weight of platinum and/or palladium and from 2 to 40 % by weight of at least one metal of the actinium series, said weight percentages indicating the amount of metal based on the total weight of carrier, supported on an acidic carrier. Use of this catalyst in a process wherein a hydrocarbon feedstock comprising aromatic compounds is contacted with the catalyst at elevated temperature and pressure in the presence of hydrogen. Process for the preparation of the above catalyst, which process comprises incorporating the catalytically active metals into the carrier followed by drying and calcining.

L'invention concerne un catalyseur supporté par un véhicule acide, comprenant 0,1 à 15 % en poids de platine et/ou de palladium et 2 à 40 % en poids d'au moins un métal de la série des actinium, lesdits pourcentages en poids indiquant la quantité de métal par rapport au poids total du véhicule. Elle porte aussi sur l'utilisation de ce catalyseur dans un procédé dans lequel la charge d'hydrocarbures comprenant des composés aromatiques est mise en contact avec le catalyseur à des température et pression élevées. Elle se rapporte enfin au procédé de préparation dudit catalyseur, qui consiste à incorporer les métaux à action catalytique au véhicule, à sécher et à calciner le tout.
