Crystal form: γ-AL2O3 type
Molecular formula: AL2O3•nH2O(0<n≤0.8)
Molecular weight: 102 <molecular weight ≤ 117
Physical and chemical properties: This product is a white, spherical porous substance, non-toxic, odorless, non-pulverizing, insoluble in water and ethanol.
Our company has successfully developed patented technology products. The carrier is made of alumina as the main material, and appropriate active additives (such as: MO-Al, Ni-Al, Mn-Al, Ti-Al, CO-Al, K-Al, etc.) are added according to the purpose of the catalyst. Compared with similar products, the catalyst prepared by the carrier has higher activity and activity stability, and is more suitable for use under harsh conditions of high temperature, high pressure, high space velocity, and high water-gas ratio. White spherical substance, made by special process, because of its unique framework structure, it has strong affinity with active components. The product has uniform micropore distribution, suitable pore size, large pore volume, high water absorption, low bulk density, and good mechanical properties. , Has good stability. It is suitable as a catalyst carrier. The Co-Mo series sulfur-tolerant shift catalyst prepared with this product has the characteristics of good low-temperature activity, wide operating temperature range, and short vulcanization time. The catalyst is suitable for small and medium-sized synthetic ammonia plants.
