Abstract
A molecular sieve blend with improved performance characteristics produced by preparing or obtaining a hydrophilic zeolite, particularly a hydrophilic zeolite A with a low SiO2:Al2O3 ratio, preparing or obtaining a hydrophobic silicon based binder, particularly a hydrophobic colloidal silica or a hydrophobic siloxane based material, mixing the zeolite with the silicon based binder and, in one embodiment, a seed containing small quantities of a clay binding agent and the zeolite, to form a mixture, and forming the mixture into the molecular sieve blend.
