This study aims to gain a deep understanding of the reaction kinetics of gliding arc plasma reforming through a combination of simulation and experiment. By adding a thermodynamic module and conservation equations of mass and energy into the traditional 0D plasma kinetics model, an effective link between experimental diagnostics and reaction kinetics simulation is established for dry reforming of CH4 in gliding arc plasma. The plasma parameters of gliding arc are experimentally diagnosed as an electron density of 1.4 x 10(14) cm(-3), an electron temperature of 1.5 eV, and an arc gas temperature of 2500 K. The kinetics simulation is conducted based on the obtained plasma parameters and verified by the online analysis of gaseous products. As a result, the reaction mechanism is revealed by the reliable model.
Aiming at a deep understanding of the reaction kinetics of gliding arc (GA) plasma reforming, a new approach to combining simulation and experiment is reported. By adding thermodynamic module and conservation equations of mass and energy into the conventional 0D plasma kinetics model, an effective link between experimental diagnostics and reaction kinetics simulation is established for dry reforming of CH4 in GA plasma. The GA plasma parameters are diagnosed experimentally as electron density of 1.4 x 10(14) cm(-3), electron temperature of 1.5 eV, and arc gas temperature of 2500 K. The kinetics simulation is implemented based on the obtained plasma parameters and verified by the online analysis of gaseous products. Consequently, the reaction mechanism is revealed by the reliable model.
