Activated alumina is one of the major adsorbent/ desiccant used world wide for moisture removal, purification and other treatments. A highly porous form of aluminum oxide, it works both under static and dynamic conditions. Activated alumina, there are many micro-paths, so the specific surface is large. It can be used as absorbent, desiccant and catalyst carrier. It is also a kinf of trace water desiccant and the pole-molecule absorbent, according to the absorbed molecule polarization, the attachment force is strong for water, oxide, acetic acid, alkali etc., It can widely used in the deep drying of cracked gas, ethylene and propylene, hydrogen-generation, air seperation, 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 defluorination. Activated Alumina has infinite shelf life, when stored in packed condition. The active service life would depend, however, on the operating conditions of the plant, Actual application the usage of the customer. FEATURES A white or slightly red particle, ball-shaped or roll-shaped, activated alumina is insoluble in water and organic solvent, soluble in strong acids and alkalis, odorless, tasteless and non-toxic. APPICATION 1) Catalyst for recovering sulfur in the petrochemical industry 2) Excellent defluorination agent for drinking water and for recycling alkyl-hydrocarbon in alkylbenzene production 3) Reclaiming agent for de-acidic in transformer oil, and de-arsenic agent in the Acid industry 4) Adsorbent in the production of hydrogen peroxide solution 5) Catalyst for polyhydro-ammonia by substituting silica gel with ball-shaped product 6) Desiccator and purifying agent.
