Description

Technical Field

[0001] This invention relates to the field of catalysts, specifically to a metal support for improving catalytic activity. Background Technology

[0002] In the field of catalysis, metal supports serve as the basis for carrying active components, and their structural design directly affects the efficiency and stability of catalytic reactions.

[0003] Currently, most mainstream metal supports adopt a single cylindrical, plate-shaped, or granular configuration. When guiding the flow of reactants, these supports often fail to achieve sufficient diffusion and retention of reactants within the support. Due to the lack of reasonable channel guidance and structural optimization, reactants tend to flow rapidly across the support surface, resulting in insufficient contact with the active sites loaded on the inner and outer walls of the support. Consequently, some active sites cannot effectively participate in the catalytic reaction, thus limiting the improvement of overall catalytic conversion efficiency. Therefore, it is necessary to design a metal support that improves catalytic activity to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a metal support that improves catalytic activity, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a metal support for improving catalytic activity, comprising a shell, wherein the top and bottom of the shell are connected to connecting portions, and one end of the connecting portion is connected to an inner shell that passes through the inner cavity of the shell; The outer shell is fixedly connected to a plurality of drainage channels for guiding reactants into the inner cavity of the shell, and the outer shell is connected to a protrusion that passes through the inner cavity of the shell.

[0006] Preferably, a gap is provided between the two inner shells to allow the reactants to enter and contact the inner wall of the outer shell.

[0007] Preferably, the inner shell is used for the rapid entry of reactants into the inner cavity of the outer shell.

[0008] Preferably, the plurality of drainage channels are distributed in a ring at equal intervals on the surface of the outer shell, and the surface of the drainage channels is provided with a plurality of drainage holes.

[0009] Preferably, the outer side of the outer shell has several perforations.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. This metal support for improving catalytic activity loads the catalyst together in the outer shell, connecting part and inner shell during use, thereby providing a larger specific surface area for the catalyst. The inner shell and the flow channel provide a channel for the reactants to quickly enter the interior of the outer shell, and the hollow structure of the outer shell can prolong the contact time between the reactants and the active sites inside and outside the cavity.

[0011] 2. The metal support for improving catalytic activity has multiple perforations on the outer shell surface and multiple drainage holes on the outer side of the drainage channel. Multiple protrusions are provided on the outer side of the inner shell to further increase the specific surface area of ​​the support, achieve high dispersion loading of active components, and significantly improve catalytic conversion efficiency.
