Activated alumina ball for catalyst carrier

详情

Crystalline phase: γ- AAL2O3　 Molecular formula：AL2O3•nH2O Physical Properties: This product is 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 *5kg, 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.
