To reduce the emission of CO2 in the environment, carbon-based fuels can be replaced with environmentally friendly fuels such as H2. For this purpose, fuel processing of CH4 is a well-known technique for H2 production. In this work, 2-dimensional heterogeneous reactor model of autothermal reforming (ATR) of CH4 has been developed and implemented on gPROMS model builder 4.1.0®. The mass and energy balance equations have been incorporated in both gas and solid phase along the axial and radial direction in the packed bed reactor. The performance of ATR reactor has been investigated by observing the effects of temperature, pressure, steam to carbon ratio (S/C), oxygen to carbon ratio (O/C) and gas mass flow velocity (Gs) on CH4 conversion, H2 yield (wt. % of CH4) and H2 purity. The predicted results are compared with the thermodynamic data, developed on chemical equilibrium with application (CEA) software, and it is concluded that 823.15 K, 1.5 bar, S/C of 3.0, O/C of 0.45 and Gs of 0.15 kg m-2s-1 result in CH4 conversion and H2 purity up to 96% and 72% respectively.
