AA**4 High Strength Activated Alumina White ball-shaped particles, regular in particle sizes, smooth at surface, with high mechanical strength and strong adsorption of moisture, not expanding and cracking after adsorbing water, original shape kept. Used as a defluorinating agent of drinking water, a defluorinating agent of cyclical alkane in alkyl bezzenes production, a deacidifying-regenerant of transformer oil, and as a dryer, purifying agent, catalyst and carrier in chemical fertilizer, petrochemical industries. AA**6/**8 Activated Alumina White or slightly red ball-shaped particles, with higher specific surface, porosity volume, porosity diameter value and lower Na2O content. Used as a dryer, adsorbent of hydrogen peroxide production, catalyst carrier of chemical prodution. AA**1 Catalyst Carrier for New Type Hydrogenetion A white roll-shaped particle, insoluble in water and organic solvent, soluble in acidic and alkaline solutions, moisture adsorptive in air, not expanding and cracking after adsorbing water, with the characters of high strength and good thermal stability. Used as a catalyst carrier for hydrogenetion and desulfuration in petrochemical industry and chemical fertilizer production. AA**3 Catalyst Carrier for Extracting Residual Oil White ball-shaped or slightly red roll-shaped particles with high activity, high strength and good performance of water absorption and purification. Suitable for catalyst carrier in hydrogenetion reactions during extracting residual oil, also as drying agent, purifying agent and other catalyst carriers. AA**2 Catalyst for Recovering Sulphur A white roll-shaped particle, insoluble in water and organic solvent, soluble in acidic and alkaline solutions, moisture adsorptive in air, not expanding and cracking after adsorbing water, with the characters of high strength and good thermal stability.
