CBSP-XR3015 ceramic balls are also known as packing balls, inert ceramic balls, support balls, high-purity packings, alumina support balls, packing balls, etc. They are widely used as bottom filling materials for hydrocracking units, refined units, catalytic reforming units, isomerization units, demethylation units, etc. in petrochemical plants, chemical fiber plants, alkylbenzene plants, square hydrocarbon plants, ethylene plants, etc. As supporting covering materials and tower packings for catalysts, molecular sieves, desiccants, etc. in reactors. Its main function is to increase the distribution points of gas or liquid, support and protect active catalysts with low strength.
The CBSP-XR3015 series ceramic balls is classified according to the alumina content, with the characteristics of high purity, high strength, high temperature resistance, high pressure resistance, acid and alkali corrosion resistance, good thermal vibration stability, and stable chemical properties.
