Abstract: A process wherein a gas mixture of a reformate gas comprised predominantly of hydrogen and carbon oxides, and a biogas comprised predominantly of methane and carbon dioxide is passed through a pressure swing adsorption unit. Contaminants, such as carbon oxides, are adsorbed and a methane-rich stream and a hydrogen-rich stream are separately recovered. The methane-rich stream is sent to steam methane reforming that results in a reformate comprised primarily of hydrogen which is then combined with the biogas feed stream and sent to pressure swing adsorption.

Abstract: The present invention is a method for treating contaminated water streams resulting from the production of coal-bed-methane. The method of treating contaminated water streams typically includes the steps of: providing a reaction vessel that contains a bed of weak acid cation ion exchange resin beads; introducing the contaminated water stream to the reaction vessel; allowing for the exchange of hydrogen ions for sodium ions; removing the ion exchanged treated water from the reaction vessel; stopping the stream of contaminated water; and regenerating the weak cation exchange resin.
