Introduction: Activated alumina has a large capacity of absorption, large surface area, high strength and thermal stability, which is widely used as an absorber, desiccant and catalyst carrier in chemical, petrochemical and fertilizer industry. It can also widely used in the deep drying of cracked gas, ethylene and propylene, hydrogen-generation, air separation, instrument air drying and fluorine treatment for H 2 O 2 , also in the absorbing pollution material, such as H 2 S, SO 2 , HF and paraffin in the water gas.
