A solid particle bed has a sea zone and at least one island zone distributed in the sea zone, and has an upper surface, a lower surface, an axial direction and a radial direction. The island zone extends along the axial direction of the solid particle bed but does not extend to the lower surface, and the voidage of the island zone is 110-300% of the voidage of the sea zone. In the solid particle bed, the oil preferentially enters the packing area with a small voidage through the tail section of the packing area with a large voidage. As the deposition amount increases, the oil gradually changes its way by entering the packing area with a small voidage through the side of the packing area with a large voidage.

Solid particle bed, fixed bed, and oil hydrogenation method

A hydrogenation catalyst contains a hydrogenation catalyst carrier and an active hydrogenation component. The active hydrogenation component includes a Group VIB metal sulfide and a Group VIII metal compound, and the molar proportion of a substance of the Group VIII metal compound that interacts with the Group VIB metal sulfide to the total amount of the Group VIII metal compound is 60-100%. The hydrogenation catalyst has a higher active metal sulfurizing degree and a higher number of type II active centers, and can be applied to the hydrogenation treatment process of oil products such as distillate oils and residual oils.
