Introduction:

Inert Alumina ball was made from very high quality chemical-porcelain clay materials, which has quite excellent stability, high mechanical strength and resistance to thermal shock, This makes them all ideal choice for support of all types of catalyst.

 

application: As the material to support and cover catalyst in the reactor ,inert alumina ball can buffer gas or liquids flush on catalyst so as to protect catalyst.It also can improve distribution of gas or liquid in the reactor.Therefore,its widely applied in petrochemical,chemical,fertilizer,gas and environmental protection industries.
