Abstract
A nanoclay based solid sorbent is provided having a nanoclay with at least one surface, and at least one amine containing compound wherein the amine containing compound is attached to the surface, as well as a method of making it. A method of capturing carbon dioxide gas is disclosed includes passing a gas from an effluent process stream containing carbon dioxide through the nanoclay based solid sorbent and capturing the carbon dioxide gas on the surface and within the nanoclay based solid sorbent. The nanoclay based solid sorbent having the captured carbon dioxide gas is regenerated by undergoing one or more cycles of desorption of the captured carbon dioxide gas from the nanoclay. The regenerated nanoclay based solid sorbent may then be reused.
