High purity Alumina Ceramic Rasching Ring as Catalyst Carrier Materials
We're a 10 years manufacturer and exporter of the catalyst material and chemcial packing.
According to the market demand, we design and produce a series of new catalyst support material. For example the high alumina Raschig rings (cylinders) Al2O3: 85~ 99%, with excellent character of high temperature resistance, high density, good pressure drop, excellent mechnical character.
Application:
widely used in many fields, including petroleum, chemical engineering, fertilizer production, natural gas and environmental protection. They are used as covering and supporting materials of catalysts in reaction vessels and as packing in towers.
products characters:
-- High purity , alpha alumina structure ,low silica
-- Excellent thermal resistance
-- Excellent chemical stability with strong resisting of acid , alkaline and organic impregnant
-- High purity
-- Excellent inert character
-- Good hardness
-- Low water absorption
-- High density
-- Wear-high temp
