The appearance of Activated alumina for catalyst carrier:
It is white or reddish-brown sand particles, the product is non-toxic, odorless, insoluble in water and organic solvents, soluble in strong acids and alkalis.
The main application of catalyst carrier:
As a catalyst carrier, alumina microspheres have many characteristics, such as: small particles, large external surface area, fast surface catalytic reaction, easy to infiltrate with rare earth metal and other elements, and catalysts with high activity. Mainly used in petrochemical fluidized bed catalysts, pharmaceutical industry catalysts, chemical cleaning agents and desiccants.
