DX-B

DX-B activated alumina is a new hydrogenation catalyst carrier. This product shape is white strip or bead. It is insoluble in water and organic solvents, is soluble in acid and alkali solutions, and has hygroscopicity in the air. It does not swell or crack after absorbing water, and has high strength and good thermal stability.

A variety of applications including:

DX-B is used as a hydrodesulfurization or cracking hydrogenation catalyst carrier in the petrochemical and fertilizer industries.
