99% High Alumina Ball for Ethylene Dryers
XINGFENG 99% High Alumina Support Media is equal Denstone 99 Support Media. It 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 down stream equipment or foul the catalyst bed.
The XINGFENG 99% High Alumina Support Media has very excellent thermal properties, with its high density high-temperature resistance 1550°C , also it's a good choice for heat retention or equilibration media.
