<p>A catalyst for treating heavy hydrocarbon feedstocks. The catalyst comprises a calcined particle comprising a co-mulled mixture made by co-mulling inorganic oxide powder, molybdenum trioxide powder, and a nickel compound or cobalt compound, or both compounds, and then forming the co-mulled mixture into a particle that is calcined to provide the calcined particle. The calcination is conducted at a temperature such that at least 20% of the pore volume of the calcined particle is in pores of greater than 5,000 Å and less than 70% of the pore volume of the calcined particle is in the pores having a pore size in the range of from 70 to 250 Å.</p> |
