99%AL2O3 Inert Alumina Ceramic Ball – Catalyst Support Media
Application
99% high alumina ceramic balls are widely used in petroleum, chemical, fertilizer, natural gas and environmental protection industries as catalyst covering carrier materials and tower packing in reactors. It has high temperature and pressure resistance, low water absorption, stable chemical properties, resistance to acid, alkali and other organic solvents, and can withstand the effects of temperature changes during the production process. Its main function is to increase the distribution point of gas or liquid, support and protect the catalyst with low activity.
