HIGH-CALORIFIC HYBRID COAL COATED WITH BIOMASS-DERIVED CARBON COMPONENT, HIGH-CONCENTRATION HYBRID COAL SLURRY, AND METHOD FOR MANUFACTURING SAME

摘要

The present invention relates to high-calorific hybrid coal in which a coal-specific natural carbon component and an artificial carbon component are mixed together, and the re-adsorption of moisture is reduced even after drying by coating the hydrophilic surface of low-grade coal with the coal component of a biomass-derived material and reforming the resulting product such that is hydrophobic, and to a method for manufacturing same. Also provided is high-calorific hybrid coal in which the re-adsorption of moisture is substantially reduced using a two-stage drying process. Also provided are a method for manufacturing high-concentration hybrid coal slurry, which includes a step of forming hybrid coal slurry by adding hybrid coal to a dispersion medium selected from among water and alcohol, water and surfactant, and water, alcohol, and surfactant, and the high concentration hybrid coal slurry manufactured thereby.
