Activated alumina (molecular formula Al2O (3-x) (OH), 2x, 0<x<0.8) is one of the most widely used inorganic chemical products in the world. Because of its porous structure, high specific surface area and unstable transition state, active alumina has great activity. It is widely used as catalyst and catalyst carrier in petrochemical industry and chemical fertilizer industry. Activated alumina also has adsorption characteristics, so it is used as a desiccant for gas and liquid, an adsorbent for gas purification, a water defluoridation, a color and Odor Remover for industrial wastewater, etc.. Today's major industrial activated alumina products are produced by rapid dehydration. Activated alumina is a kind of calcined alumina which is finely ground and has a size of 1 m and alpha Al2O3 of 20%-90%.
