90% al2o3 inert ceramic balls
Alumina inert balls are often used in catalyst bed support .widely used in petrochemical industry, chemical industry, fertilizer industry, natural gas industry and environment protection etc. With functions as covering and supporting materials for catalyst in reactors and packing for towers. The main role of inert alumina ball is increasing the distribution of liquid and gas, holding and protecting the activated catalyst with low strength.
