Claim:
A zeolitic binder-converted composition comprising: a. a zeolite X composition having at least a first zeolite X having a mean diameter not greater than 2.7 microns, as determined by sedigraph analysis, and a second zeolite X, wherein the second zeolite X is obtained by converting a binder material to the second zeolite X and the binder material is in a range from 5 to 30 wt % of the zeolite X composition, and b. an unconverted binder material content, after conversion to the second zeolite X is complete, in a range from 0 to 3 wt % of the zeolite X composition; wherein the zeolite X composition has i. an average Si/AI framework mole ratio in a range from 1.0 to 1.5, wherein the Si/AI framework mole ratio of the first zeolite and the second zeolite are different; and ii. a relative LTA intensity not greater than 1.0, as determined by a x-ray diffraction (XRD) method using a source of CuKαradiation to obtain XRD intensities in range from 5° to 25° 2θ, wherein, the relative LTA intensity is calculated as 100 times the quotient of a ⁢ ⁢ sample ⁢ ⁢ LTA ⁢ ⁢ XRD ⁢ ⁢ intensity ⁢ ⁢ for ⁢ ⁢ the ⁢ ⁢ zeolite ⁢ ⁢ X a ⁢ ⁢ reference ⁢ ⁢ XRD ⁢ ⁢ intensity ⁢ ⁢ for ⁢ ⁢ a ⁢ ⁢ LTA ⁢ ⁢ zeolite ⁢ ⁢ reference material ⁢ ⁢ consisting ⁢ ⁢ essentially ⁢ ⁢ of ⁢ ⁢ LTA ⁢ ⁢ zeolite wherein, 1. the sample LTA XRD intensity of the zeolite X composition is the sum of the intensities for each LTA peak with Miller indices of (2 0 0), (4 2 0), and (6 2 2) at 7.27 ±0.16° , 16.29 ±0.34° and 24.27 ±0.50° 2θ, and 2. the reference XRD intensity of the LTA-type zeolite reference material is the sum of the intensities for each LTA peak with Miller indices of (2 0 0), (4 2 0), and (6 2 2) at 7.27 ±0.16°, 16.29 ±0.34° and 24.27 ±0.50° 2θ, wherein, the sample LTA XRD intensity and the reference XRD intensity are each a. obtained for a sodium-exchanged form of the zeolite X composition and the LTA-type zeolite reference material, respectively, and b. equilibrated at 50% relative humidity.
