ABSTRACT:
Disclosed herein is a dry regenerable sorbent for carbon dioxide capture from flue gas produced by fossil fuel-fired power plants including industrial boilers before being released to atmosphere or from fuel gas stream such as syngas produced by conversion of fossil fuel (e.g. gasification), by dry regenerable sorbent technology. The dry regenerable sorbent comprises: 70 wt % or less of an active component selected from solid compounds capable of being converted to metal carbonates; 70 wt % or less of a support selected from solid porous non-metallic materials capable of imparting a required specific surface area to the sorbent; and 70 wt % or less of an inorganic binder selected from cement-like, clay-like, and ceramic-like binders capable of imparting mechanical strength to the sorbent, the total weight of the solid raw materials being 100 wt %.
