Catalytic Steam Reforming

Steam reforming of methane in a packed bed reactor filled with Nickel based catalyst supported on Alumina, (Al2O3) is theoretically and experimentally studied and analyzed. State of the art Finite Element Method software, COMSOL Multiphysics is used to simulate a steady state two dimensional heterogeneous model, coupled with detailed reaction mechanisms modeling surface and gas-phase kinetics that takes into account the diffusion reaction phenomena inside the particles. The simulation results are compared favorably with experimental data. It is shown that strong axial and radial temperature gradients exist near the reactor wall The obtained results are important in design and optimizing of commercial reactors.
