Perforated ceramic ball is developed on the basis of inert ceramic ball. It has not only has adequate mechanical strength, chemical stability and thermal stability, but also has larger surface area and free void, thus increasing the fluids dispersion and flux, reduce the resistance of the system.
    Perforated ceramic ball is a new efficient support and covering material for catalyst, it is widely used in petroleum, chemical, fertilizer, natural gas and environmental protection to replace inert alumina ceramic ball. Under the same operating conditions, compared with the inert alumina ceramic ball, the vapor-liquid distribution is more uniform, the flow rate increases obviously, the system resistance is obviously reduced, and the catalyst does not agglomerate and not charred, thus prolonging the service life of the catalyst.
