Large surface area activated alumina has large surface area and big pore volume.
Because alumina has the characteristics of large specific surface area, controllable pore structure, good thermal stability, and strong adsorption capacity, it is widely used as a catalyst, catalyst carrier and adsorbent.
As a traditional catalyst carrier material, alumina has the characteristics of mature technology, adjustable pore structure, low use cost, and easy processing and shaping. It is widely used in the preparation of various catalysts. Alumina has a variety of crystal structure forms, such as η-, γ-, θ-, α-alumina and so on. When used as a catalyst carrier, different types of alumina are selected according to different reaction characteristics.
As the carrier of the catalyst, it needs to have suitable specific surface area, pore volume and pore diameter, as well as high mechanical strength. At the same time, according to the requirements of different reactions on the pore structure and surface acidity, a wide variety of alumina production processes and products have been formed. , Such as: composite alumina products containing titanium(Please read our TIO2 alumina) and zirconium used to improve the effect of alumina and active metals; alumina products containing fluorine and chlorine used to improve the acidity of the surface of the alumina carrier.
As an important part of the supported catalyst, the carrier not only improves the utilization of active components and improves the dispersion performance of active components, but also provides channels for the diffusion process of reactants and products. From the perspective of increasing the mass transfer rate, macroporous support materials have been widely used to improve the performance of catalysts in recent years. The pore structure of alumina originates from the particles or the gaps between the particles. The pore diameter of γ-alumina synthesized by conventional methods is generally less than 15nm.
