Abstract
The invention provides low-cost, non-thermal methods to transform and beneficiate bulk materials, including low rank coals such as peat, lignite, brown coal, subbituminous coal, other carbonaceous solids or derived feedstock. High pressure compaction and comminution processes are linked to transform the solid materials by eliminating interstitial, capillary, pores, or other voids that are present in the materials and that may contain liquid, air or gases that are detrimental to the quality and performance of the bulk materials, thereby beneficiating the bulk products to provide premium feedstock for industrial or commercial uses, such as electric power generation, gasification, liquefaction, and carbon activation. The handling characteristics, dust mitigation aspects and combustion emissions of the products may also be improved.
