High-throughput assessment of catalyst stability during autothermal reforming of model biogas
Résumé
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 degrees C under a feed consisting of 42% H2O, 14% CH4, 9% CO2, 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/MgAl2O4 as a robust catalyst for autothermal reforming of model biogas over 200 h time-on-stream.
