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 …

Herein, two major catalogues of zeolite separations, namely membrane separation and adsorptive separation, are discussed based on their operating mechanisms. 1.3. Membrane separation The channel dimensions of zeolites generally fall in the subnanometric scale, comparable with the kinetic sizes of small molecules.The process of adsorption involves separation of a substance from one phase accompanied by its accumulation or concentration at the surface of another. The adsorbing phase is the adsorbent, and the material concentrated or adsorbed at the surface of that phase is the adsorbate. Adsorption is thus different from absorption, a process in which ...

Liquid phase separation of 1-butene from 2-butenes on all-silica - CA2203419A1 - Liquid separation by zeolite membranes

Zeolite T is a low-silica (Si/Al 3–4) intergrowth of offretite (OFF, 1-dimensional, 12MR) and erionite (ERI, 3-dimensional, 8MR). Zeolite T membranes were evaluated in the separation of CO2 from CH 4 [141] and other gases [124] and displayed decent performance at low temperature and pressure conditions.Liquid separation by zeolite membranes .
