为了深入了解滑行电弧等离子体重整反应动力学，提出了一种模拟与实验相结合的新方法。通过在传统的等离子体动力学模型中加入热力学模块和质能守恒方程，建立了ch4在GA等离子体干重整过程的实验诊断和反应动力学模拟之间的有效联系。实验诊断出GA等离子体参数为电子密度1.4 × 1014cm−3，电子温度1.5 eV，电弧气温度2500 K。根据获得的等离子体参数进行了动力学模拟，并通过在线气体产物分析进行了验证。结果表明，该模型可靠地揭示了反应机理。
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 CH4in GA plasma. The GA plasma parameters are diagnosed experimentally as electron density of 1.4 × 1014cm−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.
