Product performance:
Macroporous activated alumina microspheres are white particles in appearance, insoluble in water and organic solvents, soluble in strong acids and alkalis.
Main uses:
As a new type of catalyst carrier, macroporous activated alumina microspheres have many characteristics, such as: small particles, large surface area, fast surface catalytic reaction speed; easy to impregnate rare earth metals and other elements; the produced catalysts have high activity, etc. They are mainly used in petrochemical fluidized bed catalysts, pharmaceutical industry catalysts, chemical purifiers and desiccants, etc.
