20090187053 | Modified ETS-10 zeolites for olefin separation - An as prepared Na-ETS-10 zeolite was modified by ion exchange with a mono-, di-, or tri-valent cation and mixtures thereof. Several of the modified ETS-10 zeolites showed improved pressure swing capacity during the selective adsorption of ethylene from an ethylene/ethane mixture, relative to Na-ETS-1 0, although the selectivity of adsorption decreased.

20090202655 | TITANOSILICATE MOLECULAR SIEVE SUPPORTED METALLIC NANODOTS AND METHODS OF USE TO ADSORB NOBLE GASES - A metal nanodot material is formed by ion-exchange with an ETS zeolite, followed by activation to form metallic nanodots. The nanodot may be formed from silver, nickel, copper, gold or a platinum group metal. | 08-13-2009 |
20090288994 | PROCESS FOR EXTRACTION OF BITUMEN FROM OILSANDS - Bitumen within raw oilsands may be cracked and fully recovered by light hydrocarbon extraction following exposure to modified natural zeolite catalysts under cracking conditions. The recovered bitumen is reduced in viscosity, with lower boiling point distributions. Effective cracking of oilsands bitumen using economical, abundant and readily disposable natural zeolites represents a significant step towards a waterless and environment friendly extraction process. | 11-26-2009 |
20100021559 | ZEOLITE SUPPORTED METALLIC NANODOTS - A metal nanodot material is formed by ion-exchange with chabazite or a chabazite-like structure, followed by activation to form metallic nanodots. The nanodot may be formed from silver, nickel, copper, gold or a platinum group metal. | 01-28-2010 |

20120135215 | ZEOLITE MEMBRANE AND METHODS OF MAKING THE SAME - A free-standing zeolite membrane and a zeolite membrane supported on a support structure are disclosed. The free-standing zeolite membrane is fabricated by mixing zeolite particles and an optional inorganic binder, forming a green body, and sintering the green body at a sufficiently low temperature so as to prevent damage to the gas selectivity properties of the zeolite particles. The supported composite zeolite membrane is fabricated by mixing a sacrificial binder, an optional inorganic binder, boehmite sol and zeolite particles to form a slurry. The slurry is then coated onto a porous support structure, dried and sintered at a sufficiently low temperature so as to prevent damage to the gas selective properties of the zeolite particles. In both membranes, the zeolite particles span the entire thickness of the membrane to provide a high selectivity path for the flow of gas to pass therethrough. | 05-31-2012 |
20130022510 | MEMBRANE STRUCTURES SUITABLE FOR GAS SEPARATION, AND RELATED PROCESSES - A method for fabricating a high-density zeolite membrane structure is described. The method includes the step of combining (i) a mineral zeolite material; (ii) at least one cement precursor; and (iii) an organic binder, with an aqueous component, to form an aqueous composite zeolite composition. The zeolite composition is then applied on a surface of a scaffold formed from a porous, metal oxide material. The zeolite composition is dried, and then heated under conditions to form a metal oxide-zeolite composite layer. This layer is exposed to a phosphate composition, under conditions sufficient to reduce the porosity to a level no greater than about 10%. A high-density zeolite cement composite membrane structure results. Related methods for separating hydrogen from a fluid stream, using the membrane structure, are also disclosed. | 01-24-2013 |
