Alumina filler ball alias: alumina ceramic ball, filler ball, inert ceramic ball, support ball, high-purity filler
Alumina filler ball use: widely used in petrochemical plants, chemical fiber plants, alkylbenzene plants, square hydrocarbon plants, ethylene plants and other plants hydrocracking units, refined units, catalytic reforming units, isomerization units, demethylation units and other bottom filling materials. As a supporting covering material and tower filler 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.
Characteristics of alumina filler balls: high purity, high strength, high temperature resistance, high pressure resistance, strong acid and alkali corrosion resistance, good thermal vibration stability, and stable chemical properties.
