Patent

CA 2672953

The invention relates to a catalyst for hydroconversion of hydrocarbons, comprising a support made from at least one refractory oxide, at least one group VIII metal and at least one group VIB metal, characterised in further comprising at least one organic compound with at least two thiol functions separated by at least one oxygenated group of formula (I) : HS-CxHyOz-SH (I), where x =1 to 20, preferably 2 to 9 and for example x = 6, y = 2 to 60, preferably 4 to 12 and z = 1 to 10, preferably 1 to 6. The invention further relates to a method for preparation, a method for activation of said catalyst and use of the catalyst for the hydrotreatment and/or hydrocracking of hydrocarbons.

L'invention concerne un catalyseur d'hydroconversion 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 comportant au moins deux fonctions thiol séparées par au moins un groupement oxygéné de formule (I) : HS-CxHyOz-SH (I) dans laquelle x est un nombre entier de 1 à 20, de préférence de 2 à 9, par exemple x est égal à 6, y est un nombre entier de 2 à 60, de préférence de 4 à 12, et z est un nombre entier de 1 à 10, de préférence de 1 à 6. Procédé de préparation et procédé d'activation dudit catalyseur, et utilisation du catalyseur activé pour l'hydrotraitement et/ ou l'hydrocraquage d'hydrocarbures.
