A method for producing a zeolitic adsorbent includes providing a zeolite material, providing a zeolite material, providing a first clay binder material and a second clay binder material, the first clay binder material having a greater median particle size than the second clay binder material, determining a desired adsorption kinetics rate for the zeolitic adsorbent, wherein the desired adsorption kinetics rate is based at least in part on a separations process in which the zeolitic adsorbent is desired to be employed, and selecting either the first clay binder material or the second clay binder material based at least in part on the determined desired adsorption kinetics rate. The method further includes blending the zeolite material and the selected first or second clay binder material to form a zeolite/binder blended system, forming a plurality of shaped zeolitic adsorbent pieces from the exchanged zeolite/binder blended system, binder-converting the clay binder material into a zeolite material, and ion-exchanging the binder-converted shaped pieces with an exchange cation to form an ion-exchanged zeolite/binder blended system. |
