MT99 High Alumina Support Media Catalyst Bed Support 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.
The MT Brand 99% High Alumina Support Media has very excellent thermal properties, also is 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
