氢气以及石化原料可以通过在旋流驱动的交流旋转滑翔弧等离子体中部分氧化甲烷来生产。研究了空气比(0.6至1.6)、外壳高度(25和45 cm)、电源电压(6.6至11.1 kV)和气体流量(6至18 L/min)对甲烷重整的影响。甲烷的转化率随着空气比的增加而增加,而氢气的选择性先增加然后下降。较高的外层覆盖是有益的,最大甲烷转化率达到80.73%。更高的电压提高了反应器的性能。随着气体流速的增加,甲烷转化率和氢气选择性都会降低,而功耗首先下降到流速为 16 L/min 时的最小值 8.23 kJ/L H2,然后再次增大。
Hydrogen, as well as petrochemical feedstock, can be produced by the partial oxidation of methane in an alternating-current rotating-gliding-arc plasma driven by swirling flow. The effects of the air ratio (0.6 to 1.6), height of outer cover (25 and 45 cm), supply voltage (6.6 to 11.1 kV), and gas flow rate (6 to 18 L/min) on methane reforming have been investigated. The conversion of methane grows with rising air ratio, whereas hydrogen selectivity first augments and then declines. A higher outer cover was beneficial, and maximum methane conversion attains 80.73%. Higher voltage improves the reactor performance. As gas flow rate grows, both methane conversion and hydrogen selectivity diminish, while power consumption first drops to a minimum value of 8.23 kJ/L H2 for a flow rate of 16 L/min and then again amplifies.
