known as guard bed, e.g., in PSA separation of air using zeolites. Herein we showed that the sizes of the pore mouths of Na-LTA zeolite (4A zeolite) could be reduced and tuned by a judicious CLD process. Single gas (CO 2,CH 4,N 2,O 2, Ar) adsorption isotherms of CLD modified samples were measured at 298 K. The high adsorption selectivities and ...Liquid separation, zeolite/polymer Zeolite/polymer mixed-matrix membranes have been investigated for liquid separations such as purification ofp-xylene [76], separation of ethanol-water mixtures [93-96] and water desalination [83]. Another potential application for zeolite/polymer mixed-matrix membranes is the separation of various liquid chemical …
