ASB High Alumina Support Media is equal Denstone 99 Support Media. It is inchemical composition99+% alpha alumina and a maximum 0.2wt% SiO 2 . 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.
The ASB
High Alumina Support Media has very excellent thermal properties, with its high
density high-temperature resistance
