- Numerical solutions are made of a cylindrical steam reformer for hydrogen production with various
boundary temperature distributions. The one-medium approach model which is suitable to porous medium for
steady state is adopted as describing the catalytic fixed bed in the reformer. CH4, H2O, CO, H2 and CO2 are
formed and destructed by the Steam Reforming(SR) reaction, the Water-Gas Shift(WGS) reaction and the
Direct Steam Reforming(DSR) reaction that make changes of temperature and concentration at the
computational node. The reformer having various boundary temperature distributions of constant, linear and
cubic shapes has the different yield rate of hydrogen in each case. In case of linear temperature distribution
having more weight of boundary temperature distribution at an inlet, production of hydrogen is accelerated
near an inlet and the yield rate is increased because an endothermic reaction actively occurs near an inlet at
which there are many reactants of SR and DSR.
