Abstract
A process for the production of a molecular sieve adsorbent blend product with improved performance characteristics produced by preparing a zeolite powder, preparing a highly dispersed attapulgite fiber binder, mixing the zeolite powder with the highly dispersed attapulgite binder to form a mixture, forming molecular sieve adsorbent products into a shaped material and calcining the shaped material, wherein the tapped bulk density of the highly dispersed attapulgite fibers measured according to DIN/ISO 787 is more than about 550 g/ml.
