Activated alumina ball is a white sphere, insoluble in water and organic solvent, soluble in strong acidic and alkaline solutions, moisture adsorptive in air, not expanding and cracking after adsorbing water. Activated alumina ball has the characters of high strength, resistance to sulfate poisoning and good thermal stability. It is often used as a catalyst in the sulfur recovering unit for treating gases with sulfuric acid containing in petrochemical and other industries, with its high inversion rate, long durability and effective de-sulfurizing on exhaust gases. Activated alumina ball is lso applied in oil refinery with H2S acidic gas, natural gas de-sulfur, city coal-gas and petrochemical industries.
