摘要： 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.

摘要： A method for treatment of a carbonaceous feedstock such as coal or biomass. The method comprises adsorbing an oxidizing agent selected from an oxygen containing gas, hydrogen peroxide, ozone and oxidizing acids from a liquid phase of an aqueous mixture comprising water and a carbonaceous feedstock onto the surface of the and the carbonaceous feedstock to produce an aqueous mixture with the liquid phase having a reduced content of the oxidizing agent carbonaceous feedstock having oxidizing agent adsorbed on a surface thereof, and heating this aqueous mixture to a temperature and for a sufficient time to partially oxidize and solubilize at least a portion of the carbonaceous feedstock. The reaction products may be chemically or physically separated, recycled to the heating step and/or subjected to microbial digestion in order to generate one or more desirable products from the carbonaceous feedstock. The solid portion of the reaction products may be further processed to be used in the paper industry.
