Abstract
A method for solubilizing a carbonaceous feedstock. The method includes steps of reacting a mixture of the carbonaceous feedstock with a metal oxide including a metal at a first, higher oxidation state to reduce the metal of the metal oxide to a second, lower oxidation state by releasing at least one oxygen atom from the metal oxide. The released oxygen from the metal oxide is used to oxidize the carbonaceous feedstock. At least a portion of the metal or metal oxide containing the metal at the second, lower oxidation state is then oxidized to the metal oxide containing the metal at the first, higher oxidation state for reuse in the reaction step.
