Minimising CO2 Emissions from Coal Gasification | IntechOpen

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 ...

Shell Coal Gasification Process an overview ScienceDirect

The Shell coal gasification process (SCGP) uses an up flow, entrained flow gasifier operating on a dry feed at slagging temperatures (Fig. ).The up flow arrangement allows separation of syngas and slag largely within the reactor itself. Typically, there are four side mounted burners located in the lower part of the reactor. The vessel containment uses a membrane wall, which has a ...
