NOVELTY - A composition comprises processed biomass/coal blended compact aggregate which contains greater than or equal to 10 wt.% coal having energy density of less than or equal to 21 MMBTU/ton and greater than or equal to 10 wt.% processed biomass consisting of processed organic-carbon-containing feedstock with characteristics that include energy density of greater than or equal to 17 MMBTU/ton and water-soluble intracellular salt content which is decreased by greater than or equal to 60 wt.% on a dry basis for the processed organic-carbon-containing feedstock from that of unprocessed organic-carbon-containing feedstock which is the source of the processed organic-carbon-containing feedstock.    USE - A composition.    ADVANTAGE - The method allows the productive use of coal fines which comprise less than or equal to 50 wt.% of coal mining output and currently stockpiled with low possibility of transporting the coal fines because of their potential explosive nature. The low water-soluble intracellular salt content of processed biomass substantially reduces adverse corrosive wear and maintenance cleaning of the devices. The uniform low water content and uniform, high energy density of beneficiated organic-carbon-containing feedstock used to make the low energy coal/processed biomass aggregates allows for a wide variety of renewable organic-carbon-containing feedstock to be used in the heating subsystems of the process in a cost efficient manner. During the beneficiation section of the process, the substantial reduction of water-soluble salts reduces the adverse results that occur with the subsequent use of the processed organic-carbon-containing feedstock. Energy needed to remove water from unprocessed organic-carbon-containing feedstock to a content of less than or equal to 20 wt.% and a substantial amount of the water-soluble salt is significantly lower than for conventional processes.    DETAILED DESCRIPTION - A composition comprises processed biomass/coal blended compact aggregate which contains greater than or equal to 10 wt.% coal having energy density of less than or equal to 21 MMBTU/ton and greater than or equal to 10 wt.% processed biomass consisting of processed organic-carbon-containing feedstock with characteristics that include energy density of greater than or equal to 17 MMBTU/ton and water-soluble intracellular salt content which is decreased by greater than or equal to 60 wt.% on a dry basis for the processed organic-carbon-containing feedstock from that of unprocessed organic-carbon-containing feedstock which is the source of the processed organic-carbon-containing feedstock. Processed biomass/coal blended compact aggregate is made from unprocessed organic-carbon-containing feedstock converted into processed organic-carbon-containing feedstock with beneficiation sub-system and blended with coal into a blended compact aggregate in a blending sub-system. An INDEPENDENT CLAIM is included for preparation of processed biomass/coal blended compact aggregate which involves inputting into a system comprising 1st-3rd subsystem components the raw material consisting of coal and renewable unprocessed organic-carbon-containing feedstock that includes free water, intercellular water, intracellular water, intracellular water-soluble salts, and plant cells containing cell walls that include lignin, hemicellulose, and microfibrils within fibrils, passing unprocessed organic-carbon-containing feedstock through beneficiation sub-system process to result in processed biomass having water content of less than or equal to 20 wt.% and water soluble intracellular salt content that is reduced by greater than or equal to 60 wt.% on a dry basis for the processed organic-carbon-containing feedstock from that of the unprocessed organic-carbon-containing feedstock, and passing processed biomass through blending sub-system process, to be joined with coal.
