Estimating the term…
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, characterized 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.
A hydrotreating catalyst comprising a support 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 the Elements, characterized in that it further includes at least one organic compound comprising at least two thiol functional groups separated by at least one oxygen-containing group of formula (I):
The catalyst as claimed in one of the preceding claims, characterized in that the organic compound of formula (I) is chosen from 2-mercaptoethyl ether and 1,8-dimercaptodioxaoctane (DMDO).
