Activated Alumina For Catalyst

This product is one of the most widely used catalyst carriers,according for about 70% of industrial supported catalysts.Alumina has many kinds of crystalline form and different characteristics.Even the same form has different properties depending on its different origin,such as density,pore structure  and specific surface area.
