Crystalline phase: γ- AL2O3 Molecular formula: AL2O3•nH2O Physical Properties: Activated alumina ball for catalyst carrieris a white,spherical porous material with the property of non-toxic, odorless, non-powder, insoluble in water and ethanol. Packaging: The product is double-layer packaging, outer is woven bag and inner is plastic film bag, net weight 25kg, special packaging alternative. White spherical material by special fabrication, as the skeleton has a unique structure, it is strong affinity with the active component. The porous of the product are uniform distribution , the pore size is suitable ,the pore volume is large, the water absorption is high, the accumulation density is low, the mechanical property is good. It is suitable for catalyst carrier. The Co-Mo series of catalyst agent made by this products has the property of good low-temperature activity , widely use temperature range and short time of vulcanization. And it is very suitable for small and medium ammonia plant.
