Quantity : 1000kg Price : 10USD/kg
Inert alumina ceramic ball is widely used in many fields, such as petroleum, chemical engineering, fertilizer, environmental industry, etc. Being the covering and supporting material and tower packing for catalyst in the reactor, the ceramic ball has features of high intensity, high chemical stability and thermal stability, it withstands high temperature and pressure during the process, and also resists the corrosion from the acid, alkali and other organic solvent. The leading effects of ceramic ball are to increase the distributing spots of gas or liquid, also support and protect the activated catalyst from the rushing of the gas and liquid inside of the reactor.
