A process for hydroprocessing a heavy hydrocarbon oil, comprising contacting a heavy hydrocarbon oil in the presence of hydrogen with a mixture of hydroprocessing catalyst I and hydroprocessing catalyst II wherein
- catalyst I comprises a Group VIB metal component and optionally a Group VIII metal component on a porous inorganic carrier, said catalyst having a specific surface area of 100-180 m2/g, a total pore volume of at least 0.55 ml/g, and a pore size distribution for inhibiting sediment formation and promoting asphaltene removal such that at least 50% of the total pore volume in pores with a diameter of at least 20 nm (200 Å) and at least 65% of the total pore volume in pores with a diameter of 10-120 nm (100-1200 Å), wherein less than 25% of the total pore volume of catalyst I is in pores having a diameter of 10 nm (100 Å) or less, and
- catalyst II comprises a Group VIB metal component and optionally a Group VIII metal component on a porous inorganic carrier, said catalyst having a specific surface area of at least 100 m2/g, and a pore size distribution for providing catalytic activity and inhibiting sediment formation such that a total pore volume of at least 0.55 ml/g, 30-80% of the pore volume in pores with a diameter of 10-20 nm (100-200 Å), and at least 5% of the pore volume in pores with a diameter of at least 100 nm (1000 Å), wherein less than 25% of the total pore volume of catalyst II is in pores having a diameter of 10 nm (100 Å) or less, and
- wherein catalyst I has a larger percentage of its pore volume in pores with a diameter of at least 20 nm (200 Å) than catalyst II.
A mixture of catalysts comprising
- a catalyst I which comprises a Group VIB metal component and optionally a Group VIII metal component on a porous inorganic carrier, said catalyst having a specific surface area of 100-180 m2/g, a total pore volume of at least 0.55 ml/g, and a pore size distribution for inhibiting sediment formation and promoting asphaltene removal such that at least 50% of the total pore volume in pores with a diameter of at least 20 nm (200 Å) and at least 65% of the total pore volume in pores with a diameter of 10-120 nm (100-1200 Å), wherein less than 25% of the total pore volume of catalyst I is in pores having a diameter of 10 nm (100 Å) or less, and
- a catalyst II which comprises a Group VIB metal component and optionally a Group VIII metal component on a porous inorganic carrier, said catalyst having a specific surface area of at least 100 m2/g, and a pore size distribution for providing catalytic activity and inhibiting sediment formation such that a total pore volume of at least 0.55 ml/g, 30-80% of the pore volume in pores with a diameter of 10-20 nm (100-200 Å), and at least 5% of the pore volume in pores with a diameter of at least 100 nm (1000 Å), wherein less than 25% of the total pore volume of catalyst II is in pores having a diameter of 10 nm (100 Å) or less, and
- wherein catalyst I has a larger percentage of its pore volume in pores with a diameter of at least 20 nm (200 Å) than catalyst II.
