CA 2359960

The present invention relates to a process for the preparation of a hydroprocessing catalyst, to the catalyst composition obtainable by said process, and to the use of said catalyst composition in hydroprocessing applications. Said process comprises the steps of combining and reacting at least one Group VIII non-noble metal component in solution and at least two Group VIB metal components in solution in a reaction mixture to obtain an oxygen-stable precipitate, and sulphiding the precipitate.

Cette invention concerne un procédé de préparation d'un catalyseur d'hydrocraquage, une composition catalytique obtenue d'après ce procédé, ainsi que l'utilisation de cette composition dans des applications d'hydrocraquage. Ce procédé consiste à combiner et faire réagir au moins un composant métal non noble du groupe VIII en solution et au moins deux composants métal du groupe VIB en solution dans un mélange de réaction, ceci de manière à obtenir un précipité stable sur le plan de l'oxygène. Ce procédé consiste ensuite à sulfurer le précipité.
