NOVELTY - A composition comprises processed biomass pellet composition consisting of processed organic-carbon-containing feedstock with characteristics that include energy density of greater than or equal to 17 MMBTU/ton, water content of less than or equal to 20 wt.%, and water-soluble intracellular salt content that is decreased by greater than or equal to 60 wt.% on a dry basis for processed organic-carbon-containing feedstock from that of unprocessed organic-carbon-containing feedstock. The processed biomass pellet is made from unprocessed organic-carbon-containing feedstock that is converted into processed organic-carbon-containing feedstock.    USE - A composition.    ADVANTAGE - The low salt content of processed biomass pellets 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 processed biomass pellets allow for a wide variety of renewable organic-carbon-containing feedstock to be used in pelletizing section of the process in a cost efficient manner.    DETAILED DESCRIPTION - A composition comprises processed biomass pellet composition consisting of processed organic-carbon-containing feedstock with characteristics that include energy density of greater than or equal to 17 MMBTU/ton, water content of less than or equal to 20 wt.%, and water-soluble intracellular salt content that is decreased by greater than or equal to 60 wt.% on a dry basis for processed organic-carbon-containing feedstock from that of unprocessed organic-carbon-containing feedstock. The processed biomass pellet is made from unprocessed organic-carbon-containing feedstock that is converted into processed organic-carbon-containing feedstock with a beneficiation sub-system, and into processed biomass pellet with a pelletizing subsystem that is made less than or equal to 40% lower energy than expended to make an unprocessed biomass pellet. An INDEPENDENT CLAIM is included for preparation of processed biomass pellets which involves inputting into a system comprising 1st and 2nd sub-systems a 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 1st sub-system, a beneficiation sub-system process, to result in processed organic-carbon-containing feedstock 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 processed organic-carbon-containing feedstock from that of unprocessed organic-carbon-containing feedstock; and passing processed organic-carbon-containing feedstock through 2nd sub-system, a pelletizing sub-system process, to result in processed biomass pellets, which is a solid renewable fuel composition having energy density of greater than or equal to 17 MMBTU/ton, water content of less than or equal to 10 wt.%, and water-soluble intracellular salt that is decreased by greater than or equal to 60 wt.% on a dry basis for processed organic-carbon-containing feedstock from that of unprocessed organic-carbon-containing feedstock, and made with less than or equal to 40% lower energy than expended to make current unprocessed biomass pellets.
