Abstract: Catalytic and/or adsorbent compositions are formed with greater flexibility to optimize various properties, such as strength and catalytic activity by employing a synthetic clay binder having a small particle size, e.g., an average particle size no greater than about 100 nm. Embodiments of the present invention comprise compositions containing a catalytic component and/or adsorbent component and laponite which functions as a binder either alone or with an additional binder component. Embodiments of the present invention further include a catalytic and/or adsorbent composition containing an inorganic binder and laponite as a lubricant to facilitate shaping, as by extrusion.

Abstract: Purification of a hydrogen-based gas mixture containing impurities such as carbon monoxide, nitrogen and methane is effected by contacting the gaseous mixture with a zeolite adsorbent which is a shaped product comprised of at least 95%, as determined on the basis of the moisture equilibrium adsorption value, of a low-silica type X zeolite having a SiO2/Al2O3 molar ratio of 1.9 to 2.1. The zeolite adsorbent is preferably ion-exchanged with lithium and/or calcium. The zeolite adsorbent is preferably prepared by a process including a step of contacting with a caustic solution a calcined product of a mixture of a low-silica type X zeolite and kaolin clay whereby the kaolin clay is converted to a low-silica type X zeolite.

Abstract: There is disclosed a plate-shaped pressed body (wafer) produced from an inorganic sorbent and a binder, having a thickness of less than 700 nullm, which is produced by the process of compressing a mixture of the inorganic sorbent, the binder, and optionally water and compression aids at a pressure of at least 70 MPa, wherein the weight ratio of dry sorbent to dry binder is between about 4 and 0.7 and the water content of the mixture, measured at 160null C., is between 8 and 20%; and calcining the resulting pressed body at temperatures of at least about 500null C., until the water content is substantially removed.

Abstract: An adsorption/desorption process for selectively removing nitriles from a hydrocarbon feedstock includes the steps of: (a) providing a hydrocarbon feedstock having a nitrile content of less than or equal to about 400 ppm; (b) providing an adsorbent for selective removal of nitrile from a hydrocarbon feedstock comprising a substantially homogeneous mixture of a cationic nonacidic zeolite and an inorganic oxide matrix, the zeolite having an accessibility index of between about 0.1 to about 0.4; (c) contacting the feedstock and the adsorbent at nitrile adsorption conditions whereby at least about 80% of the nitrile content is adsorbed by the adsorbent during contact with at least about 200 volumes of the feedstock per volume of the adsorbent so as to provide a used adsorbent having nitrile molecules adsorbed thereon; and (d) contacting the used adsorbent with a desorbent at desorption conditions so as to remove the nitrile molecules and provide a renewed adsorbent.

Abstract: Novel, hollow, low-density agglomerates for use in sealed insulating glass windows to adsorb water vapor, and optionally organic materials, present in the cavity between the two glazings. These agglomerates provide sufficient but not excessive amounts of zeolitic and other adsorbents when used to fill all portions of the spacer tube located at the peripheral sides of the double glazed unit, thereby greatly facilitating the filling of such spacer tubes and the fabrication of the overall unit.
