The process involves gasification of coal, which in turn will produce synthetic gas (a mix of CO+H2). The synthetic gas can be liquefied to its fuel equivalent in presence of cobalt/ironbased catalysts at higher pressure and temperature. However, liquefied coal emits twice as much CO2 as burning oil. It also emits a large volume of SO2.
