YIQUAN high-quality Activated alumina:
Activated Alumina is white ball with much micro-paths, so the specific surface is large. It can be used asabsorbent desiccant and catalyst carrier.
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 water gas, especially in the drinking water defluorination.
Molecular Formula: Al2O3 • nH2O (0<N≤0.8)
