Claim:
A hydroprocessing catalyst comprising a carrier based on at least one refractory oxide, at least one metal of group VIII and at least one metal of group VIB of the Periodic Table of Elements, characterized in that it also comprises at least one organic compound selected from the alkenediols of formula (I) in which R 1 represents a C 2 -C 10 alkenylene group, a C 6 -C 18 arylene group or a C 7 -C 18 alkylene-arylene group; and each R 2 independently represents a hydrogen atom, C 1 -C 18 alkyl, C 2 -C 18 alkenyl, C 6 -C 18 aryl, C 3 -C 8 cycloalkyl, C 7 -C 20 alkylaryl or C 7 -C 20 arylalkyl group, or the two R 2 groups together form a C 2 -C 18 divalent group, it being possible for the carbon chain of the R 2 groups to contain or bear one or more heteroatoms selected from S, N and O.
