Abstract
In the hydrocarbon oil production method, mixed oil containing atmospheric residue and deasphalted oil is brought into contact with a demetallizing catalyst in the presence of a hydrogen gas, and the mixed oil subjected to the demetallizing process is brought into contact with a desulfurizing catalyst in the presence of a hydrogen gas. The demetallizing catalyst optionally includes a low-reactivity catalyst. A part of a metallic composition contained in the mixed oil is a decomposable metallic composition. The amount of vanadium in the decomposable metallic composition is x % relative to the amount of vanadium in a whole vanadium-containing compound, the volume of the low-reactivity catalyst is y vol % relative to the total demetallizing catalyst:0<x100, 0<y≦100, and x−50≦y2.6x−99.
