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

Abstract

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% H₂O, 14% CH₄, 9% CO₂, and 7% O₂ 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.
