Mathematical modeling of diesel autothermal reformer geometry modifications

Recent Advances in Structured Catalytic Materials Development for Conversion of Liquid Hydrocarbons into Synthesis Gas for Fuel Cell Power Generators

“…HD was used as a model fuel in the calculations. To build a stationary model using Comsol Multiphysics software (version 6.0), the catalytic block was represented by a homogeneous porous medium, and the computational domain was defined in a two-dimensional axisymmetric geometry [ 94 , 95 , 96 , 98 ].…”

“…Thus, experimental studies of diesel fuel reforming on the structured Rh/Ce 0.75 Zr 0.25 O 2 -Al 2 O 3 /FeCrAl catalytic block in the ATR and SR processes allowed the development of kinetic and mathematical models that provide a qualitatively adequate and quantitatively accurate description of experimental data [ 94 , 95 , 96 , 98 ].…”

“…Since the coefficient of thermal expansion (CTE) of high-temperature metal alloys twice exceeds that of oxide coatings, the latter often suffer cracking and destruction during heating. This problem was addressed in recent works on the development of a catalyst for diesel fuel ATR, carried out at the Boreskov Institute of Catalysis, SB RAS [ 18 , 48 , 49 , 50 , 51 , 90 , 91 , 92 , 93 , 94 , 95 , 96 , 97 , 98 , 99 ]. An elegant approach has been proposed based on supporting a needle-shaped coating instead of a continuous catalytic layer [ 90 ].…”
