| 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 characterised in that it also comprises at least one organic compound having formula (I) or (II) in which each R 1 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 R 1 groups together form a divalent group at C 2-18 , and R 2 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. |
