Raschig Ring Alumina Carrierr FC-RRC

Raschig ring alumina carrier FC-RRC

Crystal Form: γ-Al₂O₃ or θ-Al₂O₃

Description:

1.High-purity Alpha and Gamma Alumina structure.

2.High Crush Strength

3. Good performance in resistance to heat and impact

4. Both as catalyst and catalyst support

Application:

The FC-RRC 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. Could be used in drying tower, absorption tower, scrubbing tower, regeneration tower in chemistry, metallurgy, oxygen generation, etc.
