1、Product Description
MH Porous Ceramic Ball is also called filtering ball. It is made by 20~30% pores inside the inert ceramic ball.
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.

3、Size
Porous ceramic balls are divided into 12 grades by reference to Al2O3 content varied from 25% to 80%, and
every more 5% constitutes a grade, but 12 sizes by reference to the diameter, such as Φ3,Φ6,Φ8,Φ10,Φ13,Φ16
,Φ20,Φ25,Φ30,Φ38,Φ50 andΦ75.
The products in other grade and sizes can be designed and manufactured if to the user's request.
