High-throughput assessment of catalyst stability during autothermal reforming of model biogas

The long-term stability of Ni-based catalysts for autothermal reforming of model biogas has been assessed in a six parallel-flow reactor set-up implemented to test simultaneously six different catalysts at 700 °C under a feed consisting of 42% H 2 O, 14% CH 4 , 9% CO 2 , and 7% O 2 in argon. The reproducibility of catalyst performance measured in the 6 parallel reactors was ascertained using a commercial Ni-based catalyst. A screening of 12 catalyst formulations identified 5-0.05 wt% Ni-Rh/MgAl 2 O 4 as a robust catalyst for autothermal reforming of model biogas over 200 h time-on-stream. A six parallel-flow reactor set-up was implemented to assess the long-term stability of Ni-based catalysts for autothermal reforming of model biogas.
