porous porcelain beads ceramic balls as supporting material

6mm 8mm 10mm 13mm 16mm al2o3 porous porcelain beads ceramic balls as supporting material Porous ceramic balls not only support and cover the catalyst, but also filter and eliminate the impurities. Porous ceramic balls are also called filtering balls. They are made by drilling on the inert ceramic balls. Therefore it can be used for not only supporting and covering the catalyst, but also filtering and eliminating the impurities of grain, gelatin, asphaltine, heavy metals or iron ions, etc, which is less than 25µm. When the porous balls are set on the top of the reactor, the impurities which failed to be eliminated in former process could be absorbed in the pores of the ceramic balls, thereupon protect the catalyst and prolong the operating cycle of the system.
