A high heat resistance plate catalyst, Ni-Al<SUB>2</SUB>O<SUB>3</SUB>/alloy clad catalyst, made by anodization technology, was applied to a methane steam reforming system. In this work, a two-dimensional coaxial model was proposed to simulate a cylinder methane steam reformer by using this novel catalyst. For the momentum balance, the two widely used models, the Navier–Stokes (NS) and plug flow (PF) models were both validated by the experimental data. All the results indicate that the NS model is in good agreement with the experimental values while the PF model works well in a limited range. On the basis of the model, the effects of catalyst thermal conductivity, channel height, reaction temperature and the length of the catalyst bed on the reactor performance were also discussed.
