Perforated ball is based filler mass transfer effects and media, through the study of filler fluid properties, on the basis of inert ceramic ball shape formed by the transformation of the design of a new type of support, covered with a spherical packing. The main principle is: the use of corundum and mullite as the main phase of the product, feldspar and kaolin sintered body glass bridge structure, the use of high mechanical strength alumina sintered body of corundum and mullite crystals, high temperature resistance thermal shock properties, oxidation, wear-resistant, low chemical activity, resistant to acid corrosion.

Perforated ball to ball diameter to open single or multiple circular solve the problem of a single sphere swing resistance. Type Perforated ball curved lines stripes or bump convex surface to improve the porosity and specific surface area of the filler layer, liquid redistribution ability, excellent vapor-liquid dispersion, and its performance under the same conditions Inert alumina ceramic ball comparison, 12% of the porosity is increased, the contact surface area is increased by 25%, 15% reduction in resistance. And it can accommodate, interception coke powder, gum, heavy metal impurities and avoid the deposition of coke on the catalyst bed, catalyst poisoning.
