For the Activated alumina, there are varied merits, for instance, the properties of absorption, catalytic activation, porous, high dispersion and large specific surface areas etc. It adapts to the drying of gases and liquids. Furthermore, it can be applied to be as the absorbents, drying agents, catalysts and carriers during the reactions in the fields of petroleum, chemical fertilizer and chemical industry.
According to the inner main crystal phase, there are Y and X-P types. In accordance with the usage, it can be divided into activated alumina absorbent, activated alumina drying agent and activated alumina catalyst carrier.
