    Alumina has been found to exist at least 8 form, they are α- Al2O3, θ-Al2O3, γ- Al2O3, δ- Al2O3, η- Al2O3, χ- Al2O3, κ- Al2O3 and ρ- Al2O3, their respective macroscopic structure properties are also different. Gamma activated alumina is a cubic close packed crystal, insoluble in water, but soluble in acid and alkali. Gamma activated alumina is weak acidic support, has a high melting point 2050 ℃, alumina gel in hydrate form can be made into the oxide with high porosity and high specific surface, it has transition phases in a wide temperature range. At higher temperature, due to dehydration and dehydroxylation, the Al2O3surface appears coordination unsaturated oxygen (alkali center) and aluminum (acid center), with catalytic activity. Therefore, alumina can be used as carrier, catalyst and cocatalyst.
    Gamma activated alumina could be powder, granules, strips or others. We could do as your requirement.γ-Al2O3, was called “ activated alumina”, is a kind of porous high dispersion solid materials, because of its adjustable pore structure, large specific surface area, good adsorption performance, surface with the advantages of acidity and good thermal stability, microporous surface with requisite properties of catalytic action, therefore become the most widely used catalyst, catalyst carrier and chromatography carrier in the chemical and oil industry, and plays an important role in the oil hydrocracking, hydrogenation refining, hydrogenation reforming, dehydrogenation reaction and automobile exhaust purification process.Gamma-Al2O3 is widely used as catalyst carrier because of the adjustability of its pore structure and surface acidity. When γ- Al2O3 is used as a carrier, besides can have the effects to disperse and stabilize active components, also can provide acid alkali active center, synergistic reaction with the catalytic active components. The pore structure and surface properties of catalyst depend on γ-Al2O3 carrier, so high performance carrier would be found for specific catalytic reaction by controlling the properties of gamma alumina carrier.

    Gamma activated alumina is generally made of its precursor pseudo-boehmite through 400~600℃ high temperature dehydration, so the surface physicochemical properties is largely determined by its precursor pseudo-boehmite, but there are many ways to make pseudo-boehmite, and different sources of pseudo-boehmite leads to the diversity of gamma – Al2O3. However, to those catalysts with special requirements to alumina carrier, only rely on the control of precursor pseudo-boehmite is difficult to achieve, must be taken to prophase preparation and post processing combining approaches to adjust the properties of alumina to meet different requirements. When the temperature is higher than 1000 ℃ in use, alumina occurs following phase transformation: γ→δ→θ→α-Al2O3, among them γ、δ、θ are cubic close packing, the difference only lies in the distribution of aluminum ions in tetrahedral and octahedral, so these phase transformation does not cause much variation of the structures. Oxygen ions in alpha phase are hexagonal close packing, aluminum oxide particles are grave reunion, specific surface area declined considerably.

  • Alpha alumina catalyst support

    Alpha alumina catalyst support

    α-Al2O3 is a porous material, which is often used for supporting catalysts, adsorbents, gas phase separation materials, etc. α-Al2O3 is the most stable phase of all alumina and is usually used to support catalyst active components with a high activity ratio. The pore size of the α-Al2O3 catalyst carrier is much larger than the molecular free path, and the distribution is uniform, so the internal diffusion problem caused by the small pore size in the catalytic reaction system can be better eliminated, and the deep oxidation side reactions can be reduced in the process for the purpose of selective oxidation. For example, the silver catalyst used for ethylene oxidation to ethylene oxide uses α-Al2O3 as the carrier. It is often used in catalytic reactions with high temperature and external diffusion control.

  • (CMS) PSA Nitrogen Adsorbent Carbon Molecular Sieve

    (CMS) PSA Nitrogen Adsorbent Carbon Molecular Sieve

    *Zeolite molecular sieves
    *Good price
    *Shanghai sea port

     

    The Carbon molecular sieve is a material containing tiny pores of a precise and uniform size that is used as an adsorbent for gases. When the pressure is high enough, the oxygen molecules, which pass through the pores of CMS much faster than the nitrogen molecules, are adsorbed, while the coming out nitrogen molecules will be enriched in gas phase. The enriched oxygen air, adsorbed by the CMS, will be released by reducing the pressure. Then the CMS is regenerated and ready for another cycle of producing nitrogen enriched air.

     

    Physical properties

    Diameter of the CMS granule: 1.7-1.8mm
    Period of adsorption: 120S
    Bulk density: 680-700g/L
