Product Description
This series product consists of X-ρ activated alumina, which is made by quick dehydration method, and pseudoboehmite gel or powder, which is made by carbonization method and neutralization process. They are prepared by advanced forming technology, which have the characteristics of stable specific surface area, strong crushing strength, low abrasive rate, proper pore structure, low impurities and good impregnation of active component etc. Different catalyst carrier with different crystal phase, pore size and impurity content can be prepared by different process according to the customer’s requirements. They are widely used in the petrochemical industry, HDS and PSA, like sphere, spherical gear, trifolium, hollow and raschig ring.
Applications:
This product is widely used in petrochemical industry, hydro desulfurization and catalyst carrier, with the shapes of mocrospherical, spherical gear, trifolium, muti-leaf, hollow shape and Raschig ring etc.
