Product Description

Active ceramic balls (SW active ceramic balls) are a new type of reactor support filler. They are made by introducing a small amount of transition metal oxides into inert ceramic balls. They not only have the high-temperature resistance and high mechanical strength characteristics of inert ceramic balls but also serve functions such as filtering, dispersing gas and liquid, covering, and supporting catalysts. Additionally, they possess certain catalytic activity and play an auxiliary catalytic role in olefin saturation, desulfurization, and denitrification processes. In processes such as hydrofining of fractionated oil, hydrocracking, reforming pre-hydrogenation, and benzene hydrogenation, filling active ceramic balls at the top of the catalyst bed in the reactor can preliminarily hydrogenate mono-olefins and diolefins in secondary processed feedstock, thereby reducing catalyst fouling. Filling active ceramic balls at the bottom of the catalyst bed can remove thiols and other substances generated during certain reactions. Using active ceramic balls can effectively improve the space utilization of the reactor and, to some extent, protect the catalyst from poisoning and sintering, thereby extending the catalyst's service life.
