Abstract[English]
The present invention describes a method for preparing an amorphous silica-alumina-based material having incorporated therein, by means of precipitation, at least one acid solution and/or suspension of an aluminium source together with colloidal alumino-silicate particles having the structure of zeolite and conferring on the final material improved acidity relative to silica-alumina of the prior art, thereby providing a catalyst or a catalyst support that can be used in hydroconversion reactions.[French]
La présente invention décrit un procédé de préparation d'un matériau à base de silice alumine amorphe dans lequel on incorpore par précipitation avec au moins une solution et/ou une suspension acide d'une source d'aluminium, des particules colloïdales d'alumino-silicate ayant la structure de zéolithe et conférant audit matériau final une acidité améliorée par rapport aux silices alumines de l'art antérieur, de manière à fournir un catalyseur ou un support de catalyseur utilisable dans les réactions d'hydroconversion.
