The present invention relates to a hydrocarbon hydrotreating catalyst comprising a refractory oxide-based support, a Group VIII metal and a Group VIB metal. The catalyst has the formula (I): [Chemical 1] Wherein R 1 represents a C 2 to C 10 , preferably a C 2 to C 4 alkenylene group, a C 6 to C 18 arylene group or a C 7 to C 18 alkylene-arylene group, and each R 2 is independently represent hydrogen atom or C 1 -C 18 alkyl group, C 1 -C 18 alkenyl groups, C 6 -C 18 aryl group, C 3 -C 8 cycloalkyl group, or C 7 -C 20 alkylaryl or arylalkyl, Or two R 2 groups together form a divalent C 2 -C 18 group, wherein the carbon chain of the R 2 group is at least one heteroatom selected from S, N and O At least one organic compound selected from alkene diols). The invention also relates to a process for the production of such a catalyst and its use for hydroprocessing or hydroconversion. |
