5. Activated Alumina Ball
Crystal: Y- AL2O3,χ-ρAL2O3 type
Molecular formula: AL2O3nH2O (0 <N<=0.8)
Molecular weight: 102 ~ 117
Physical Properties: This product is a white, spherical porous material, non-toxic, odorless, non-powder, insoluble in water, ethanol.
 Packaging: The product is double-layer packaging, outer woven bag lined with plastic bags, bag, net weight 25KG, special packaging alternative.
White spherical material, special fabrication, because the skeleton has a unique structure, so strong affinity with the active component, the product porous uniform distribution of pore size suitable large pore  volume of high water absorption, bulk density is small, good mechanical properties, has good stability, suitable for a catalyst carrier, desiccant, fluoride removal agent, transformer adsorbent. So that the FDA prepared CO-MO sulfur-tolerant shift catalyst with a low-temperature activity is good, the use of a wide temperature range, curing time is short and so on, the catalyst for small and medium ammonia plant.
