17-23% Alumina Ceramic balls also known as Ceramic Catalyst Support Balls, is equal to Denstone® 57 Support Media.

Chem Enviro company supplies a range of industrial grade inert ceramic support media, are widely used as the covering or supporting materials of the catalyst in the reactors and the packing in the columns in such varied areas, for examples, refineries, synthesis gas and other petrochemical processes.

Products to these specifications are manufactured from very high quality chemical-porcelain clay materials, which has quite excellent stability, high mechanical strength and resistance to thermal shock, This makes them all ideal choice for support of all types of catalyst.

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
