The shape, size and mechanical strength of the catalyst must match the corresponding catalytic reaction process 

and catalytic reactor and comply with the requirements of service performance.

For fluidized bed, the catalyst need to ensure fluidized state, The catalyst must have good fluidity, our γ- alumina 

microspheres can fully meet the fluidized bed requirements.

HIGHLION can produce gamma γ-alummina microsphere with diameter 110-150μm, we can adjust particle 

size distribution, pore volume, specific surface area and other indicators according to customers' requirements.
