Title: Electrochemical production of metal hydroxide using metal silicates

Abstract

Systems are described for dissolving metal silicates to: produce metal hydroxide; remove carbon dioxide or other acid gases from the atmosphere or other gas mixture by reacting such gases with the metal hydroxide; penetrate or excavate metal silicates; extract metals or silicon-containing compounds from metal silicates; and produce hydrogen and oxygen or other gases.

Electrochemical formation of hydroxide for enhancing carbon dioxide and acid gas uptake by a solution

Patent Rau, Gregory Hudson [Castro Valley, CA]

A system is described for forming metal hydroxide from a metal carbonate utilizing a water electrolysis cell having an acid-producing anode and a hydroxyl-producing cathode immersed in a water solution of sufficient ionic content to allow an electric current to pass between the hydroxyl-producing cathode and the acid-producing anode. A metal carbonate, in particular water-insoluble calcium carbonate or magnesium carbonate, is placed in close proximity to the acid-producing anode. A direct current electrical voltage is provided across the acid-producing anode and the hydroxyl-producing cathode sufficient to generate acid at the acid-producing anode and hydroxyl ions at the hydroxyl-producing cathode.
