widely applied in fertilizer, gas and environmental protection industries.
Inert alumina ceramic ball
With the characters of high mechanical strength, high chemical stability, and excellent heat endurance, inert alumina ball can resist high temperature, high pressure, acid, alkali, salt and various organic solvents.
As the material to support and cover catalystin the reactor, inert alumina ball can buffer gas or liquid's flush on catalyst so as to protect catalyst. It also can improve distribution of gas or liquid in the reactor.
