Gamma Alumina Catalyst
This series of products 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.
Description
Technical Parameters
The appearance is white or reddish, non-toxic, tasteless, insoluble in water and organic solvents, soluble in acid and alkali.
This series of products 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. We can produce the catalyst carrier in different crystal phases, different sizes, different impurities content, different appearance shape according to the user's requirements.
This product is widely used in petroleum and chemical industry, hydrogenation desulfurization, low catalyst carrier. The shape of a ball, bar, trefoil, leaf shape, hollow shape and Raschig ring.
