Syngas Production via Reverse Water‐Gas Shift Reaction over a Ni‐Al 2 O 3 Catalyst: Catalyst Stability, Reaction Kinetics, and Modeling

The synthesis of liquid fuels from CO 2 , e.g., separated from flue gases of power plants, and H 2 from renewables, i.e., 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) and synfuel production by Fischer‐Tropsch synthesis. Research is concentrated on the RWGS using a Ni‐catalyst. The catalyst shows an appropriate performance in catalyzing the RWGS. The catalyst is stable at technically relevant temperatures. The intrinsic and effective kinetics were determined and considerations on a technical application of the process are proposed.
