Ceramic Porous Ring

A new catalyst bed support media  - Ceramic  Porous Ring, with excellent character of high temperature resistance, high density, good pressure drop, excellent mechanical character.

 

These products are made from Alpha alumina that has a very low silica content. The high purity and strength make this an ideal choice for high temperature and stream applications where it is necessary to avoid the problems of leached silica coating downstream equipment or fouling or polluting the catalyst bed.

 

The character:

Alpha alumina structure, high purity

Excellent thermal properties

High pressure insistance

Excellent chemical stability with strong resisting of acid, alkaline and organic impregnant.
