Product performance
Alumina microspheres are a new type of catalyst carrier. They have the characteristics of fine particles, large specific surface area, and fast surface catalytic reaction speed. At the same time, they are easy to impregnate and load elements such as rare earth metals. The produced catalyst has high activity.
The catalyst prepared by the large pore volume active alumina support has higher activity, selectivity and conversion than the catalyst prepared by the small pore volume support, so the large pore volume alumina support (0.6-1.0ml / g) is a future development direction.
Application area
It is used in petrochemical fluidized bed catalyst carrier, pharmaceutical industry catalyst carrier, chemical purification agent and desiccant.
