Active alumina
Active alumina sorbent is an especial alumina for good adsorb performance, efficiency catalyse. It is good dryer used for oil, fertilizer, and chemical reaction process by many absorbent, desiccant, catalysts.
Active alumina sorbent have two type: Y & X－P，base on the purpose have Active alumina sorbent、Active alumina dryer and Active alumina carrier。
