Product Detail
The Chemxin 99 High Alumina Support Media is inchemical composition99+% alpha alumina and a maximum 0.2wt% SiO 2 . Because of its highalumina 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 Chemxin 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.
