Inert Ceramic Balls as Catayst Supports
The 23-25% Al2O3 Inert Alumina Ceramic Balls are used as catalyst, absorbent, desiccant and drying agent in petroleum, chemical, fertilizer, natural gas and environmental protection industries. As a catalyst reactor coverage tower packing materials and support, the major role is to increase distribution of gas or liquid, support and protect the intensity of low strength activity catalyst.
