Thermodynamic modelling and optimization of oxy-reforming and oxy-steam reforming of biogas by RSM

In this study, a comparative thermodynamic equilibrium calculation of biogas oxy-reforming and oxy-steam reforming processes to produce syngas has been conducted by Aspen Plus simulation software. The effects of temperature (600-800°C), pressure (1-20 atm), and inlet O2/CH4 (0-1.0), H2O/CH4 (0-3.0),...

Zusammenfassung:In this study, a comparative thermodynamic equilibrium calculation of biogas oxy-reforming and oxy-steam reforming processes to produce syngas has been conducted by Aspen Plus simulation software. The effects of temperature (600-800°C), pressure (1-20 atm), and inlet O2/CH4 (0-1.0), H2O/CH4 (0-3.0), and CO2/CH4 (0.3-1.0) mole ratios on the equilibrium compositions of products were determined. The operation of the process was optimized using Gibbs free energy minimization method and statistical approach: response surface methodology (RSM). Optimum operating conditions CH4/CO2/O2 = 1:0.51:0.12 at 788°C and 1 atm for oxy-reforming and CH4/CO2/H2O/O2 = 1:0.63:0.19:0.07 at 780°C and 1 atm for oxy-steam reforming were obtained to reach maximum H2 yield, CH4 and CO2 conversions by minimizing carbon selectivity to produce syngas for methanol production
