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。 Item/ performance Active alumina sorbent Active alumina dryer Active alumina activator carrier Normal High standard Normal High standard type Y X-P Y Chemic composition Al2O3 ≥92 ≥93 ≥90 ≥95 Na2O ≤0.3 others 6月8日 <10 <5 Physical properties.
