alumina chemical filling ball high purity filling material abrasive medium catalyst covering material
Product name : Alumina ceramic ball
Specification : HY-TCQ-03
Product use :
widely used in petrochemical plants, chemical fiber plants,
alkylbenzene plants, aromatics plants, ethylene plants, natural gas
and other workshops hydrocracking unit, refining unit, catalytic
reforming unit, isomerization unit, demethylation unit and other
bottom filling materials. It is used as a support covering material
and tower packing for catalysts, molecular sieves, and desiccants
in the reactor. Its main role is to increase the gas or liquid
distribution point, support and protect the catalyst strength is
not high.
Characteristics : high purity, high strength, high temperature
resistance, high pressure resistance, strong acid and alkali
corrosion resistance, good thermal shock stability, stable chemical
properties.
Alumina content :
AL2O3 : 90 %, 92 %, 95 %, 99 %, 99.5 %
Physical indicators :
