Abstract:
Preparation of a catalyst having at least one metal from group VIII, at least one metal from group VIB and at least one support; in succession: i) one of i1) contacting a pre-catalyst with metal from group VIII, metal from group VIB and support with a cyclic oligosaccharide naming at least 6 α-(1,4)-bonded glucopyranose subunits; i2) contacting support with a solution containing a precursor of metal from group VIII, a precursor of said metal from group VIB and a cyclic oligosaccharide composed of at least 6 α-(1,4)-bonded glucopyranose subunits; or i3) contacting support with a cyclic oligosaccharide composed of at least 6 α-(1,4)-bonded glucopyranose subunits followed by contacting solid derived therefrom with a precursor of metal from group VIII and a precursor of metal from group VIB.
