#$%^&*AU2012359295A120130919.pdf#####ABSTRACT The present invention provides high-calorific hybrid coal and its fabrication method in which a coal-inherent natural carbon ingredient and an artificial carbon ingredient are combined by coating a carbon ingredient of biomass-derived material on a hydrophilic surface of low-rank coal and thus changing the hydrophilic surface into a hydrophobic surface so as to suppress re-absorption of moisture after drying. Also, the present invention provides high-calorific hybrid coal with significantly lower moisture reabsorption by using a two-step drying process. And also, the present invention provides high concentration hybrid coal slurry and its fabrication method in which the above-mentioned hybrid coal is added to one dispersion medium selected from water/alcohol, water/surfactant, and water/alcohol/surfactant.
