In recent years, biogas production from biomass degradation has attracted the attentionof researchers and industry. This paper reports a wideresearch investigation carried out on biogas reforming processes (SR, ATR and POX) finalised to produce syn-gas at fuel cellsfeed grade. To this end a mathematical model, realized in Aspen Plus software, has beenimplemented to simulate biogas reforming processes. Through the mathematical model, simulations were carried out, varying reforming process, reaction temperature and reaction pressure, to obtain the outlet syngas compositions and theenergy required for each case studied. The energy balance for each process wasdeveloped as available energy in outlet syngas divided by inlet required energy to theprocess. Simulations results allowed to perform an efficiency comparison of reformingprocesses studied in this article. Finally, the comparison of process efficiencies at different thermo-barometric conditions has allowed to establish the best reformingprocess from the energetic point of view. The comparison between values of processefficiency gives an useful indication about their reliability to be integrate with fuel cell systems.

Abstract
In recent years, biogas production from biomass degradation has attracted the attentionof researchers and industry. This paper reports a wideresearch investigation carried out on biogas reforming processes (SR, ATR and POX) finalised to produce syn-gas at fuel cellsfeed grade. To this end a mathematical model, realized in Aspen Plus software, has beenimplemented to simulate biogas reforming processes. Through the mathematical model, simulations were carried out, varying reforming process, reaction temperature and reaction pressure, to obtain the outlet syngas compositions and theenergy required for each case studied. The energy balance for each process wasdeveloped as available energy in outlet syngas divided by inlet required energy to theprocess. Simulations results allowed to perform an efficiency comparison of reformingprocesses studied in this article. Finally, the comparison of process efficiencies at different thermo-barometric conditions has allowed to establish the best reformingprocess from the energetic point of view. The comparison between values of processefficiency gives an useful indication about their reliability to be integrate with fuel cell systems.Pubblicazioni consigliate
