Abstract: The removal of one or more of the gases CO2, N2 and H2S from gas mixtures containing at least one of said gases with use of an 8-ring zeolite having a Si:Al ratio from about 1:1 to about 1000:1. The preferred gas mixture is a natural gas feedstream and the preferred 8-ring zeolite is DDR.

Abstract: A process for the separation of one or more heavy hydrocarbon gases from a gas mixture containing heavy hydrocarbon gas components and methane. The process is conducted in swing adsorption apparatus containing adsorbent contactor having a plurality of flow channels and wherein 20 volume percent or less of the open pore volume of the contactors, is in the mesopore and macropore range.

Abstract: The present invention relates the separation of a target gas from a mixture of gases through the use of engineered structured adsorbent contactors in pressure swing adsorption and thermal swing adsorption processes. Preferably, the contactors contain engineered and substantially parallel flow channels wherein 20 volume percent or less of the open pore volume of the contactor, excluding the flow channels, is in the mesopore and macropore range.

Abstract: The separation of a target gas selected from a high pressure gas mixture containing said target gas as well as a product gas using a swing adsorption process unit. A turboexpander is used upstream of the swing adsorber to reduce the pressure of the high pressure gas mixture. A compressor is optionally used downstream of the swing adsorber to increase the pressure of the target gas-containing stream for injecting into a subterranean formation.

Abstract: A method for capturing CO2 from the ambient air by the use of solid tethered amine adsorbents, where the amine adsorbents are tethered to a substrate selected from the group of silica, metal oxides and polymer resins. The tethered amines are joined to the substrate by covalent bonding, achieved either by the ring-opening polymerization of aziridine on porous and non-porous supports, or by the reaction of mono-, di-, or tri-aminosilanes, with silica or a metal oxide having hydroxyl surface groups. The method includes the adsorption of CO2 from ambient air, the regeneration of the adsorbent at elevated temperatures not above 120° C. and the separation of purified CO2, followed by recycling of the regenerated tethered adsorbent for further adsorption of CO2 from the ambient atmosphere.

Abstract: The present invention relates to the separation of one or more of CO2, N2, and H2S gas components from a gas mixture containing at least a second gas using a swing adsorption process unit. The adsorbent contactors of the swing adsorption process unit are engineered structured adsorbent contactors having a plurality of flow channels wherein 20 volume percent or less of the open pore volume of the contactors is in the mesopore and macropore range.
