High calorific hybrid coal biomass -derived carbon component is coated , high- density hybrid coal slurry , and process for their preparation .

摘要

The present invention relates to a hydrophilic surface that is present in low feed coal is coated with the carbon component of the biomass-derived material, and by modifying the hydrophobicity, re-adsorption of moisture is suppressed even after drying, the coal-specific natural high calorific value of the hybrid coal has a carbon component and artificial carbon component was hybridized, and methods of making the same. The present invention by using the two-step drying process, to provide a hybrid coal of high calorific value for re-adsorption was markedly inhibited water. Furthermore, the present invention is a hybrid coal water / alcohol, water / surfactant, or a water / alcohol / is added to any one of the dispersion medium selected from among surfactants, to form a hybrid coal slurry comprising the steps, a method for producing a high density hybrid coal slurry, and thereby provide a high density hybrid coal slurry is produced.
