High Alumina Ball

99% pure alumina Ceramic Ball is equal Denstone 99 Support Media. It is in chemical composition99+% alpha alumina and a maximum 0.2wt% SiO2 . Because of its high alumina content and low silica (SiO2 ), it’s a very excellent and ideal product for high temperature and steam applications, such as secondary reformers in ammonia processing, where leached silica will coat downstream equipment or foul the catalyst bed.

99% High Alumina Support Media has very excellent thermal properties, with its high density high-temperature resistance 1550℃ , also it’s a good choice for heat retention or equilibration media.
For its superior chemical resistance, it’s suitable for applications in olefin processes, such as ethylene dryers, where there’s the polymerization problem.

Typical Applications:
Hydrotreating
Hydrogenation
Hydrodesulphurisation
Isomerisation
Methanation
Shift Conversion
Catalytic Cracking
Molecular Sieve Driers
Silica Gel Driers
Sulphuric Acid Converters
Claus Reactors
Mercury, Sulphur and Chloride Guards
