| 摘要 |
A self activating catalyst for treating heavy hydrocarbon feedstocks that comprises a calcined particle comprising a co-mulled mixture made by co-mulling inorganic oxide powder, molybdenum trioxide powder, and a nickel compound and then forming the co-mulled mixture into a particle that is calcined to thereby provide the calcined particle. The self activating catalyst may be activated when it is contacted under suitable process conditions with a heavy residue feedstock having high nickel, vanadium and sulfur concentrations.
