catalyst support media

1.High strength
2.High chemical stability
3.High thermal stability
It is widely used 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.
