The present application relates to methods and apparatus for CO 2 sequestration. Provided are processes, methods and apparatus for carbon sequestration utilizing a catalytic scheme configured to provide a high concentration of hydrated CO2 in the vicinity of a sequestration agent. The reactants are combined with the catalyst such that at least two regions of controlled catalytic activity are formed to surround at least the interface between the sequestering agent and the aqueous solution containing dissolved CO 2 . Suitable reactants include various sequestering agents, catalysts, and carbon dioxide dissolved in an aqueous solution (eg, seawater). Possible products include bicarbonate and metal cations. |
