Product Description
- 产品描述
-
Perforated ceramic balls and microporous ceramic balls are new products 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
Perforated ceramic balls increase the porosity and specific surface area of the packing layer, have strong liquid redistribution ability, excellent gas-liquid dispersion performance, and 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%. They 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.
Widely used in petroleum, chemical, and natural gas industries as a replacement for inert ceramic balls, serving as support and coverage cushion materials for catalysts and as tower packing.
