Hydrotreating process with mixed catalysts

摘要

Disclosed is a process for hydrotreating a hydrocarbonaceous feed wherein the feed is contacted in a mixed catalyst bed at a temperature of about 200 DEG C. to 450 DEG C., in the presence of hydrogne, which catalyst bed is comprised of: (a0 one or more catalysts comprised of at least one metal selected from Group VIB and at lease one metal selected from Group VIII of the Periodic Table of the Elements, on an inorganic oxide support material; and (b) one or more catlayst represented by MM'aSx where M is Cr or one or more divalent promoter metals selected from Mn, Fe, Co, Ni, Cu and Zn; M' is one or both of MO and W; x is 0.5 to 9, and a=1 when Cr is not one of metals represented by M, and 0.5
