Activated Alumina

AIM-Activated Alumina with its large specific surface area   provides numerous micro-paths. It is ideal to be employed as absorbent, desiccant and catalyst carrier. It absorb polarized molecules and can be used as trace water desiccant and the pole-molecular absorbent and its attracting force is strong for water, oxide, acetic acid, alkali etc. Additionally, The DE fluorinate effect of the activated alumina is really good. It has high strength, low abrasion, no soften in water, no powdery no crack and no expansion. It can widely use in the deep drying of cracked gas, ethylene and propylene, hydrogen-generation, air separation, instrument air drying and fluorine treatment for H2O2, also in the absorbing pollution material, such as H2S, SO2, HF and paraffin in the waste gas, especially in the drinking water DE fluorinate.
