3-5mm CAS 1344-28-1 Activated alumina use in Air Gas Drying
Activated alumina much micro-paths, so the specific surface is large, it can be used as absorbent desiccant and catalyst carrier, also a kind of trace water desiccant and the pole-molecular absorbent, the products with high strength, low abrasion, no soften in water, no expansion, no powdery and no crack, It can widely used 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 defluorinate.
