Abstract

Suivant ce procédé, on mélange un support à base d'oxyde minéral réfractaire avec une solution commune d'un composé d'un métal des groupes IVA, IB, VIB, VIIB et VIII de la table périodique et d'un acide carboxylique soufré choisi parmi les acides carbothioliques, carbothioniques, carbodithioliques et mercaptocarboxyliques, afin de déposer le composé métallique sur la surface externe du support, la solution commune étant tout d'abord, avant mélange avec le support vieillie pendant un laps de temps de 5 minutes à 24 heures à une température de 25 à 100 degrés C, le temps de vieillissement décroissant lorsque la température croît.
