Abstract

Carbonaceous feedstock is at least partially oxidized using a concentrated metal ion solution that is regenerated in an electrochemical hydrogen gas producing process. The at least partially oxidized feedstock and/or hydrogen are then advantageously used as an energy carrier in a downstream process.

Claims

AMENDED CLAIMS received by the International Bureau on 13 February 2008 (13.02.2008)
1. A method of oxidizing a carbonaceous feedstock, comprising: combining a metal and a solubility- enhancing compound to form a metal-containing solution having a metal concentration of at least 0.3M; wherein the solubility-enhancing compound is present al a concentration and has a composition effective to increase solubility of the metal over solubility of the same metal in sulfuric acid in an amount of at least 10%; wherein the solubility-enhancing compound lias a composition effective to resist oxidation under conditions at which the metal is electrochemical Iy oxidized from a reduced form; combining the carbonaceous feedstock with the metal-containing solution to thereby al least partially oxidize the feedstock and form the reduced form of the metal; optionally elcctrochcmically regenerating the metal from the reduced form of the metal, wherein the step of regenerating is carried out under conditions effective to produce hydrogen; and using at least one of the hydrogen and the at least partially oxidized feedstock as an energy carrier in a subsequent reaction.
