The classification of chemical filling ball

The inert alumina ceramic chemical filling ball has stable molecular structure, acid resistance, alkali resistance, high temperature resistance, good thermal stability, extremely low water absorption, and high compressive strength. It is an ideal carrier for various types of catalysts and is widely used in petroleum, chemical, fertilizer, Industries such as coal chemical industry and environmental protection play the role of supporting and covering catalysts.


Inert alumina ceramic ball is referred to as inert ceramic ball or inert filler ceramic ball. It is a kind of ceramic accumulation material mainly processed and produced by high-quality kaolin, feldspar, and alumina powder materials. Inert alumina ceramic balls are processed from high-quality chemical porcelain clay materials. The inert alumina ceramic balls have the characteristics of high strength, high chemical stability and thermal stability. The inert alumina ceramic balls can withstand high temperature, high pressure, acid and alkali. , Salt and various organic solvents. Inert ceramic balls are used as the support and covering material of the catalyst in the reactor, which can buffer the impact of the liquid and gas entering the reactor on the catalyst, protect the catalyst, and improve the distribution of liquid and gas in the reactor.
