dc.description.abstract | Pyrolysis kinetics of a gingko nut shell in a thermo gravimetric analyzer (TGA) and the steam gasification and combustion kinetics of chars from gingko nut shell in a thermobalance reactor have been determined. The effects of the reaction temperature (350°C - 950°C) and steam partial pressure (0.4 - 0.8 atm.) on the gasification kinetics and that of oxygen partial pressure (0.4 - 0.8 atm.) on the combustion kinetics have been determined in a thermobalance reactor. The activation energy and the pre-exponential factor were determined from the Arrhenius plot based on the shrinking core model. In the steam gasification reaction, the activation energy and the pre-exponential factor are found to be 40.8 kJ mol-1 at 1.7 s-1 atm.-1, respectively. The reaction order is found to be 0.32 with respect to water partial pressure at 750°C. In the combustion reaction, the activation energies and pre-exponential factors are found to be 92.8 kJmol-1 at 136.8 s-1atm-1 and 9.2 kJmol-1 at 0.012 s -1atm-1 in the reaction control and the pore-diffusion control regimes, respectively. | - |
