99% Alumina Rasching Ring as Catalyst Carrier
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.
