An oxidic Co-M® catalyst presulfided by the SULFICAT ® process has been studied by XPS. Results indicate that the strong interaction of the alkylpolysulfide with the solid provokes a partial reduction of both the sulfur and molybdenum ions. Treated under hydrogen, the adsorbed species decompose at t
