Product Description

Zhongci High-Purity Inert Alumina Ball Catalyst Inert Ceramic Ball for Catalyst Supporting

99% pure alumina Ceramic Ball, 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.
Zhongci 99% pure alumina Ceramic Ball, has very excellent thermal properties, with its high density high-temperature resistance 1550ºC, also it's a good choice for heat retention or equilibration media. 
 

Zhongci 99% pure alumina Ceramic Ball,  it's suitable for applications in olefin processes, such as ethylene dryers, where there's the polymerization problem. It also has a good resistance to high temperature, high pressure, acid, alkali and various organic solutions. The alumina ball has been most often used as catalyst support in petroleum, chemical fiber plant, aromatic factory, catalytic reforming unit, fertilizers, natural gas, environmental protection and more.
