    Activated alumina carrier

    Activated alumina carrier

    This series of products is made of X-ρ activated alumina produced by rapid high temperature dehydration method and fake aluminum monohydrate gum produced by continuous carbonization method, using advanced molding technology. It has the characteristics of stable specific surface area, good compressive strength, low wear, suitable pore structure, low impurity content and good impregnation characteristics of active components. And according to user requirements, using different process conditions, adjust the physical and chemical properties to produce different crystal phase, different pore size, different impurity content of catalyst carrier.It is widely used in petrochemical industry, hydrodesulfurization, low variation catalyst carrier.
