Abstract

The invention discloses a catalyst carrier, which belongs to the technical field of the protection and supporting product structure of a fixed bed catalyst which is a solid catalyst product used in industries of oil refining, chemicals, gas processing and the like. The catalyst carrier comprises a central hole, a convex part, a top part, a cylinder, a concave part, a groove and a body, wherein the body comprises the cylinder and at least one convex part arranged around the cylinder, which are formed in one piece; the cylinder has a cylindrical solid structure, and a through central hole is arranged along an axial direction; and the at least convex part has a blade cylinder-shaped, toothed or arch cylinder-shaped solid structure, and the protruding top part of the at least one convex part is provided with at least one groove running through the axial direction. When the technical scheme of the invention is adopted, lateral loading capacity is improved, the intensity of lateral pressureis improved, the voidage of a supporting protective agent is improved, and the pressure drop of the bed of the catalyst is reduced.

Description

technical field [0001] The invention relates to a catalyst carrier, which belongs to the technical field of solid catalyst product structures used in industries such as oil refining, chemical industry, and gas treatment, and specifically belongs to the technical field of product structures for protecting and supporting fixed bed catalysts in solid catalyst products. Background technique [0002] At present, the shapes of supporting and protecting medium structures of catalyst beds in oil refining, chemical industry, gas treatment and other industries include spherical, Raschig rings, hollow impellers, porous balls and porous cylinders. Their main disadvantages are: 1) low lateral pressure strength and easy damage; 2) low porosity and high bed resistance, which greatly affects the use efficiency of catalysts and devices. Catalyst protection and support products that can reduce the bed pressure drop, increase the side pressure strength, effectively protect the main catalyst an...
