Abstract:
1. A method for separating carbon dioxide from a flow of gas comprising carbon dioxide, said method comprising the steps of: directing said flow of gas to a gas-solid contact reactor, said gas-solid contact reactor containing at least one mesoporous sorbent, said at least one mesoporous sorbent comprising at least one metal oxide; reacting said carbon dioxide with said at least one sorbent so as to remove said carbon dioxide from said flow of gas at a temperature of about 600° C. to about 700° C., thereby converting said at least one mesoporous sorbent into spent sorbent; calcining said spent sorbent so as to liberate said carbon dioxide from said spent sorbent, thereby regenerating said mesoporous sorbent; and repeating the aforementioned steps.
