Quick Details
Specifications
The Chemxin 90 High Alumina Support Media is in chemical composition90+% 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 Chemxin 90 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.
