Ceramic Inert Ball as Catalyst Carrier Media (Al2O3: 17~22%, 23~30%, 90%, 99%)
1: Advantage of Chemshun catalyst carrier
---High purity, alpha alumina structure, low silica
--- Excellent thermal and mechanical shock resistance properties
---Excellent chemical stability with strong resisting of acid.
2: Application of catalyst carrier inert ceramic ball
----Desulfurizers
----Dehydrogenation
----Catalytic reforming
-----catalytic isomerization
-----Ethylene cracking and drying
-----Poymerization
-----Low temperature shift
-----High temperature shift
-----Methanator
------Naphtha reforming
------Methanol and dydrogen production (primarily reforming )
3: Serving Industry of catalyst supporting / covering media
----- Oil Petroleum
----- Chemical inustry
------ Chemical fertilizer
------ Natural gas
