| 摘要 |
The invention relates to a catalyst for hydroconversion of hydrocarbons, comprising a support made from at least one refractory oxide, at least one group VIII metal and at least one group VIB metal, characterised in further comprising at least one organic compound with at least two thiol functions separated by at least one oxygenated group of formula (I): HS—CxHyOz-SH (I), where x=1 to 20, preferably 2 to 9 and for example x=6, y=2 to 60, preferably 4 to 12 and z=1 to 10, preferably 1 to 6. The invention further relates to a method for preparation, a method for activation of said catalyst and use of the catalyst for the hydrotreatment and/or hydrocracking of hydrocarbons.
