Hydroprocessing Catalyst, Preparation Method Thereof and Use of Same

摘要

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 C_1-18, an alkenyl group at C_2-18, an aryl group at C_6-18, a cycloalkyl group at C_3-8, an alkylaryl or arylalkyl group at C_7-20, or the two R₁ groups together form a divalent group at C_2-18, and R₂ represents an alkylene group at C_1-18, an arylene group at C_6-18, a cycloalkylene group at C_3-7, 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.
