Raschig Ring Alumina Carrier FC-RR

Crystal Form: θ-Al₂O₃ or α-Al₂O₃

Description:

Raschig Ring Alumina Carrier FC-RR is white hollow cylindrical particles, non-toxic, tasteless, odorless, insoluble in water and ethanol..

Application:

The FC-RR type product 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. It has the characteristics of high purity, good heat resistance and mechanical shock resistance, and stable chemical properties. It is widely used in petrochemical, natural gas, coal chemical industries and other industries.
