Description:
The synthesis of liquid fuels from CO 2 (e.g. separated from flue gases of power plants) and H 2 from renewables (water electrolysis) is a concept for substituting fossil fuels in the transport sector. It consists of two steps, syngas production via reverse water-gas shift (RWGS; CO 2 + H 2 CO + H 2 O) and synfuel production by Fischer-Tropsch synthesis (CO + 2 H 2 -(CH 2 )- + H 2 O). This work concentrates on the RWGS using a Ni-catalyst. The catalyst shows an appropriate performance in catalysing the RWGS. The catalyst is stable at technically relevant temperatures (900°C). The intrinsic and effective kinetics were determined and considerations on a technical application of the process are proposed.
