1.absorbing capacity,catalytic activity,porosity 2.big specific surface area 3.used as sorbent,desiccant, activator Activated Alumina possesses Characteristics such as absorbing capacity, catalytic activity, porosity, high dispersion and big specific surface area. It is applicable to drying of gas and liquid, and be used as sorbent, desiccant, activator and other carriers in petrolic, fertilizer and chemical industries.Activated alumina be divided into Model Y and Model X~P according to their inside main crystal, and be divided into activated alumina sorbent, desiccant and activator.
