Fuel reforming processes are primarily used to generate hydrogen for fuel cells and in automotive internal combustion engines to improve combustion characteristics and emissions. In this study, biogas is used as the fuel source for the reforming process as it has desirable properties of being both renewable and clean. Two reforming processes (dry reforming and combined dry/oxidative reforming) are studied. Both processes are affected by the gas stream temperature and reactor space velocity with the second process being affected by O-2/CH4 ratio as well. Our results imply that oxidative reforming is the dominant process at low exhaust temperatures. This provides heat for the dry reforming of biogas and the overall reforming is exothermic. Increase in O-2/CH4 ratio at low temperature promotes hydrogen production. At high exhaust temperatures (> 600 degrees C), dry reforming of biogas is dominant and the overall reaction is net endothermic. (C) 2010 Professor T. Nejat Veziroglu. Published by Elsevier Ltd.
