Co-liquefaction of Thar coal with waste plastic and waste oil was carried out to get high-quality fuel from waste. Four major variables, temperature, residence time, hydrogen pressure and coal: waste plastic ratio, oil: coal and oil: waste plastic ratios were investigated. According to results, maximum oil yield was obtained at 400 degrees C temperature, 100psi pressure, 60 min residence time, and oil: coal: waste plastic ratios of 6:2:2. An FTIR result and C-13 NMR analysis have shown extracted oil contains almost 84% aliphatic compounds and 16% aromatic compounds. Among aliphatic, there is more %age of diesel fraction. Extracted residue can also be used as a fuel in cement industry and in power generation plants because it contains almost 83-84% carbon with less than 1% sulfur.
