Product Introduction
Perforated ceramic balls are a new product developed based on inert alumina ceramic balls. They are perforated along the diameter axis of the sphere, possessing certain mechanical strength, chemical stability, and thermal stability, while increasing the specific surface area and porosity, thereby enhancing material dispersion and flux, and reducing system resistance.
Product Features
Increases the porosity and specific surface area of the packing layer, with strong liquid redistribution ability and excellent gas-liquid dispersion performance. Compared with inert alumina ceramic balls under the same conditions, porosity increases by 12%, contact specific surface area increases by 25%, and resistance decreases by 15%. It can also accommodate and trap coke powder, colloids, and heavy metal impurities, preventing their deposition in the catalyst bed which causes coking and catalyst poisoning.
Application Range
Perforated ceramic balls are widely used in petroleum, chemical, and natural gas industries as a replacement for inert ceramic balls, serving as support and coverage layers for catalysts and as tower packing materials.
