 Syngas evolutionary behavior during chicken manure pyrolysis and air gasificationK.G. Burra, M.S. Hussein, R.S. Amano and A.K. Gupta Applied Energy, 2016, vol. 181, issue C, 408-415 Abstract: The evolutionary behavior of syngas composition during the pyrolysis and gasification of chicken manure was examined at different temperatures and O2 concentrations. A gas chromatography was used to quantify the syngas evolved. Pure nitrogen was used for pyrolysis while two different oxygen concentrations (21% and 10%) in nitrogen were used for gasification. Five specific temperatures examined during pyrolysis and gasification were from 600 to 1000°C in steps of 100°C. Higher O2 concentration (21%) produced higher energy yields compared to lower O2 concentrations. Initial 8–10min yield produced CO2 dominant syngas from decarboxylation after which the compositions changed to equilibrium. High temperature and low O2 concentrations yielded higher CO flow rates and amounts. Equilibrium H2 content was reduced with an increase in O2 concentration due to the rapid oxidation of H2 in the presence of oxidative environment. CH4 was obtained from thermal cracking with its evolution being similar to that of other higher hydrocarbons evolved, albeit in smaller concentration.
