An inventive adsorptive gas separation process is provided capable of producing a purified methane product gas as a light non-adsorbed product gas as opposed to a heavy desorbed exhaust gas component, from a feed gas mixture comprising at least methane, and carbon dioxide. In an embodiment of the invention, the feed gas mixture may comprise at least about 10% carbon dioxide, and the purified methane product gas may be desirably purified to contain less than about 5000 ppm carbon dioxide. In another embodiment of the invention, the feed gas mixture may co...
What is claimed is: 1. An adsorptive gas separation process for producing a purified methane product gas from a feed gas mixture comprising at least methane and carbon dioxide, wherein the feed gas mixture comprises at least about 10% carbon dioxide, and the purified methane product gas is produced by adsorption of the feed gas mixture in an adsorber in contact with at least a first adsorbent material suited for adsorbing at least a majority of the carbon dioxide in the feed gas stream, and subsequently a second adsorbent material suited for substantial...
