The AL-99 High Alumina Support Media is equal to "Denstone 99
Support Media". Because of its high alumina content and low silica
(SiO2 ) Ball 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.
For its superior chemical resistance, it's suitable for
applications in olefin processes, such as ethylene dryers, where
there's the polymerization problem. It also has a good resistance
to high temperature, high pressure, acid, alkali and various
organic solutions. The alumina ball has been most often used as
catalyst support in petroleum, chemical fiber plant, aromatic
factory, catalytic reforming unit, fertilizers, natural gas,
environmental protection and more.
