Methods for treating carbonaceous feedstocks, such as coal or biomass, are provided. The method comprises adsorbing at least one oxidant selected from an oxygen-containing gas, hydrogen peroxide, ozone, and oxidic acid, wherein the oxidizer is derived from a liquid phase of an aqueous mixture comprising water and a carbonaceous feedstock, Preparing an aqueous mixture of a reduced liquid phase and a carbonaceous feedstock on which an oxidant has been adsorbed on its surface by mixing the aqueous mixture with a carbonaceous feedstock in an amount sufficient to partially oxidize and solubilize at least a portion of the carbonaceous feedstock; ≪ / RTI > The reaction product may be chemically or physically separated and recycled to the heating step and / or may be subjected to microbial degradation, so that at least one product from the carbonaceous feedstock can be produced. The solid fraction of the reaction product can be further processed and used in the paper industry. |
