Brief
This filtering ball 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.

25% Ceramic Filtering Ball
1. Product Description
This filtering
ball 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.
