A lithium exchanged zeolite X adsorbent blend with improved performance characteristics produced by preparing a zeolite X, preparing a binder which includes highly dispersed attapulgite fibers wherein the tapped bulk density of the highly dispersed attapulgite fibers measured according to DIN/ISO 787 is more than about 550 g/ml, mixing the zeolite X with the binder to form a mixture, forming the mixture into a shaped material, ion exchanging the zeolite X at least 75% with lithium ions, and calcining the shaped material.
