Patent

CA 2595335

The invention relates to a hydrocarbon hydroprocessing catalyst comprising a support based on at least one refractory oxide, at least one metal from group VIII and at least one metal from group VIB. The inventive catalyst is characterised in that it also comprises at least one organic compound having formula (I) or (II) in which each R1 represents independently an alkyl group at C1-18, an alkenyl group at C2-18, an aryl group at C6-18, a cycloalkyl group at C3-8, an alkylaryl or arylalkyl group at C7-20, or the two R1groups together form a divalent group at C2-18, and R2 represents an alkylene group at C1-18, an arylene group at C6-18, a cycloalkylene group at C3-7, or a combination of same. The invention also relates to a method of preparing one such catalyst and to the use thereof for hydroprocessing or hydrocracking.

L'invention concerne un catalyseur d'hydrotraitement d'hydrocarbures, comprenant un support à base d'au moins un oxyde réfractaire, au moins un métal du groupe VIII et au moins un métal du groupe VIB, caractérisé en ce qu'il comprend en outre au moins un composé organique de formule (I) ou (II) dans laquelle chaque R1 représente indépendamment un groupe alkyle en C1-18, alcényle en C2-18, aryle en C6-18, cycloalkyle en C3-8, alkylaryle ou arylalkyle en C7-20, ou les deux groupes R1 forment, conjointement, un groupe divalent en C2-18, et R2 représente un groupe alkylène en C1-18, arylène en C6- 18, cycloalkylène en C3-7, ou une combinaison de ceux-ci, un procédé de préparation d'un tel catalyseur et l'utilisation du catalyseur pour l'hydrotraitement ou l'hydrocraquage.
