WHA-420 is a macro pore volume aluminum oxide gel with proper pore structure.Its total pore volume is about 0.8ml/g, the pore diamerer is between 30-150A and pore distribution gathering.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 deguming.It is also used in middle low pressure hydrogen desulfurization and dechlorination of reforming equipment.
