This product is an aluminum oxide, white powder, with high pore volume, large specific surface area and proper pore structure. It is provided with high intensity and low abrasion when the roll is made from it. It is widely used as hydrogenation catalyst carrier and in low pressure hydro-denitrification and degumming. It is also used in middle low pressure hydrogen desulfurization and dechlorination of reforming equipment.
