Perforated Ball
Perforated ball is further developed based on inert alumina ball, which is perforated through the ball body along its axes. Therefore, besides characters of high mechanical strength, high chemical stability and heat endurance, both the specific surface area and voidage for perforated ball are increased a lot.
It can improve distribution of materials and their flux. Co***ring with inert alumina ball at the same operation conditions, the voidage is increased by 12%, contacting specific surface area is increased by 25%, and resistance to fluid of material is decreased by 15%. As a result, distribution of vapor-liquid is distributed more evenly, and flow of material is increased significantly. It also absorb and withhold impurities in the form of granular, colloid and heavy metals so that it can avoid impurities depositing on the catalyst and prevent catalyst from caking or poisoning.
Therefore, perforated ball is widely applied to replace inert alumina ball in petrochemical, chemical, fertilizer, gas and environmental protection industries.
In accordance with customer specific needs, it can also carry active agents, e.g. molybdenum, nickel, cobalt, to prevent catalyst from poisoning.
