Description

Raschig ring alumina catalyst carrier is used as a covering proppant and adsorbent material for the catalyst in the reactor. Its main function is to increase the gas or liquid distribution points and support and protect the active catalyst with low strength. Raschig ring alumina catalyst carrier has the characteristics of high purity, good heat resistance and mechanical shock resistance, and stable chemical properties.
