Abstract Herein, we describe the design and operation of an indirect coal liquefaction plant with integrated coal-water slurry manufacturing, entrained flow gasification, Rectisol, and Fischer–Tropsch processes to produce liquid fuels for vehicles. The above plant contained an entrained flow gasifier (10 t/d test rig) operated using oxygen as a gasifying agent (21 bar, 1100 °C) and could stably produce synthesis gas (37.8 vol% H2, 36.4 vol% CO) at 600 Nm3/h. Due to the importance of impurities in synthetic liquid fuel production, more than 99% of H2S contained in synthesis gas was removed by the Rectisol process employing refrigerated methanol. An iron-based catalyst allowed liquid fuels containing wax, light/heavy oil, and alcohol fractions to be obtained by the Fischer–Tropsch process at a rate of 5 barrel per day, with detailed analysis confirming their compliance with various quality standards and thus their suitability for use as automobile diesel after distillation.
