Porous Aluminum Oxide Ceramic Balls For Catalytic Cracking , Catalyst Bed Support Media
Descrition:
Porous Ceramic Ball is in inert alumina ceramic balls on the basis of the development of new products, it with ball diameter as the axis for opening, already has certain chemical stability and mechanical strength, thermal stability, and add specific surface area and pore ratio, thus increasing the material of dispersion and flux, and decrease the system resistance. Can be widely used in petroleum, chemical and natural gas industry substitution inert alumina ceramic balls as catalyst coverage of supporting the packing. This product since release, deeply user favor and praise. The proof of use of the user, in the same reactor, reactor,the same operation condition, with original cover support material than steam fluid distribution more even, the flow resistance increased obviously decreased obviously, system, and catalyst not agglomeration, not scorched, thereby prolong the service life of the catalyst.
