US 9,212,324 B2 · Hydroprocessing catalyst, preparation method thereof and use of same

Abstract

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 characterized 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 C1-18, an alkenyl group at C2-18, an aryl group at C6-18, a cycloalkyl group at C3-8, an alkylaryl or arylalkyl group at C7-20, or the two R1 groups together form a divalent group at C2-18, and R2 represents an alkylene group at C1-18, an arylene group at C6-18, a cycloalkylene group at C3-7, 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.
