Abstract
A method of removing carbon dioxide from a gas can include providing a gaseous feed stream including a carbon dioxide gas and adsorbing the carbon dioxide gas with a porous carbon sorbent. The method can further include de-adsorbing the carbon dioxide and combining the carbon dioxide with a substantially pure hydrogen gas to produce at least one of methane and methanol. The adsorbing and de-adsorbing of the carbon dioxide gas can be conducted by an electric swing adsorption.
