Zibo Xiangrun's calcined aluminum oxide is made from first-grade industrial alumina powder calcined in a high-temperature tunnel kiln and then processed in a ball mill to produce aluminum oxide fine powder. This powder features high purity, stable high-temperature performance, uniform hardness, and excellent fluidity. It also possesses excellent sintering properties, making it a high-quality raw material for refractory materials and ceramic products.
Characteristics
Thermal Stability: High-temperature calcination enhances alumina's sintering resistance, making it suitable for high-temperature catalytic reactions.
Surface Acidity and Alkalinity: Calcination temperature influences the density and distribution of surface hydroxyl groups and acid sites, regulating the catalytic performance of the support.
Mechanical Strength: High-temperature calcination increases particle hardness, reducing pulverization caused by mechanical stress in industrial applications.
Controllable Pore Structure: By optimizing calcination conditions, mesoporous or macroporous alumina can be prepared, improving reactant diffusion efficiency.
Main Applications of calcined aluminum oxide
Petrochemicals: As a carrier for reactions such as hydrogenation, cracking, and isomerization.
Environmental Catalysis: Used for automobile exhaust purification and VOC oxidation.
Energy Catalysis: Provides a stable carrier in reactions such as methane dry reforming and Fischer-Tropsch synthesis.
Fine Chemicals: As an active carrier for selective oxidation and acid-catalyzed reactions.
