Traditional coaltoliquid processes use gasification with excess steam to obtain hydrogenrich syngas for downstream manufacturing of methanol or FischerTropsch liquids. Such processes are shown to produce very large amounts of CO2 directly by the WaterGasShift (WGS) reaction or, indirectly, by combustion in raising steam. It is shown how any coal gasifier can operate under autothermal ...
