Abstract:
In numerical simulations of gasification processes of complex bio oils such as pyrolysis oil, suitable chemical kinetic reaction mechanisms are required to model the gasification process of the fuel. However, due to the complex composition of bio oils, the development of such mechanisms is a challenging task. Recently, ethylene glycol has been introduced as a one component model fuel for pyrolysis oil. Even with this simplification, the resulting detailed kinetic mechanism is too large for efficient computational fluid dynamics (CFD) simulations. Therefore, in the present work, we develop three reduced reaction mechanisms for ethylene glycol oxidation starting from a detailed reaction mechanism developed earlier in our group. The reduced mechanisms are validated by computing ignition delay times and laminar flames speeds for ethylene glycol, acetaldehyde and methane, and comparing them to experimental data from literature. The validation of the three reduced mechanisms is done for pressures ranging between 1 and 16 bar, temperatures ranging between 800 and 1800 K, and fuel equivalence ratios f ranging between 0.5 and 2. It is found that all three versions of the reduced mechanisms show good agreement with experimental data.
