Estimating the term…
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.
A section of a solid particle bed (particularly an axial solid particle bed), comprising a sea zone and at least one island zone distributed in the sea zone and having an upper surface, a lower surface, an axial direction (i.e. the length direction or the direction of the material flow in the solid particle bed from the upper surface to the lower surface) and a radial direction (i.e. the cross-sectional direction or the direction perpendicular to the axial direction), wherein the island zone extends (preferably from the upper surface) 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% (preferably 130-240%, and further preferably 140-200%) of the voidage of the sea zone.
