Model:BHCG-CB-MH-004
ProductPorous ceramic ball
Porous Ceramic Balls is also called filtering balls. It is made by make 20~30% pores inside the inert ceramic balls. Therefore it can be used not only for supporting and covering the catalyst, but also for filtering and eliminating the impurities of grain, gelatin, asphaltine, heavy metals and iron ions of less than 25μm. If the porous ball is set on the top of a reactor, the impurities fail to be eliminated in former process could be adsorbed in the pores inside the balls, thereupon protect the catalyst and prolong the operating cycle of the system. As the impurities present in the materials are different, the user can select the product by their sizes, pores and porosity, or if necessary, add molybdenum, nickel and cobalt or other active components to prevent the catalyst from coking or poisoning.

Notice to ordering goods
a)When ordering goods, customers should correctly choose the outward sizes and specifications of the porous ceramic ball according to the requirement of design.
b) As to the operating temperature and the loading amounts of the related equipment, customers should consult with our technological personal, and relevantly think over the appropriate margins.
c) If it is necessary to load the active constitutions as Mo, Ni, and Co etc., customers had better put forward it while ordering goods.
The products in other grade and sizes can be designed and manufactured if to the user's request.
