The study was dedicated to the mathematical modeling of the catalytic autothermal reforming (ATR) of diesel fuel – effective method for hydrogen production. The structured wire mesh Rh/Ce0.75Zr0.25O2-δ-η-Al2O3/FeCrAl catalyst was tested in pilot scale reactor and showed high efficiency in studied diesel autothermal reaction conditions. The process simulation was carried out by commercial software COMSOL Multiphysics in 2D axisymmetric geometry. The catalyst module was simulated as homogeneous porous medium. Reaction model included diesel oxidation, diesel steam reforming, water-gas shift reaction, CO methanation, CO oxidation and hydrogen oxidation. Fitting the experimental results including product distribution and temperature profile allowed to define the kinetic parameters corresponding to the best fit. The suggested simple quasi-homogeneous model describes experimental results (module temperature and outlet gas composition) with a good accuracy and could be used for process optimization and up-scaling.
