Abstract
Provided is a method of economically modifying low rank coal (LRC) to be high grade coal having minimized water re-absorption and minimized spontaneous ignition possibility while saving energy by coating heavy oil directly on coal without using solvent oil. Provides is a method of modifying coal using palm oil residue, including milling the coal, homogenously mixing the palm oil residue with the milled coal, melting the palm oil residue mixed with the coal so as to be coated on a surface of the coal, and simultaneously drying moisture in the coal, cooling the dried coal, and briquetting the cooled coal.
