Patent

CA 2595319

The invention relates to a hydrocarbon hydroconversion catalyst comprising a carrier based on refractory oxide, a metal of the group VIII, and a metal of the group VIB. Said catalyst is characterised in that it also comprises at least one organic compound selected from the alkene diols of formula (I) wherein R1 represents a C2-10 alkenylene group, preferably C2-4 alkenylene, a C6-18 arylene group, or a C7-18 alkylene-arylene group, and each R2 independently represents a hydrogen atom or a C1-18 alkyl group, a C1-18 alkenyl group, a C6-18 aryl group, a C3-8 cycloalkyl group, or a C7-20 alkylaryl or arylalkyl group, or the two groups R2 together form a divalent C2-18 group, the carbonated chain of the R2 groups containing or carrying at least one heteroatom selected from S, N and O. The invention also relates to a method for preparing one such catalyst, and to the use of said catalyst for hydrotreatment or hydroconversion.

L'invention concerne un catalyseur d'hydroconversion d'hydrocarbures, comprenant un support à base d'oxyde réfractaire, un métal du groupe VIII et un métal du groupe VIB, caractérisé en ce qu'il comprend en outre au moins un composé organique choisi parmi les alcène-diols de formule (I) dans laquelle R1 représente un groupe alcénylène en C2-10, de préférence en C2-4, un groupe arylène en C6-18 ou un groupe alkylène-arylène en C7-18, et chaque R2 représente indépendamment un atome d'hydrogène ou un groupe alkyle en C1-18, alcényle en C1-18, aryle en C6-18, cycloalkyle en C3-8, alkylaryle ou arylalkyle en C7-20, ou les deux groupes R2 forment, conjointement, un groupe divalent en C2-18, la chaîne carbonée des groupes R2 pouvant contenir ou porter un ou plusieurs hétéroatomes choisis parmi S, N et O, un procédé de préparation d'un tel catalyseur et l'utilisation du catalyseur pour l'hydrotraitement ou l'hydroconversion.
