Product Description
Ceramic ball as Catalyst Support alumina catalyst support alumina catalyst
Ceramic ball 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.
