研究了外加电压波形对介质阻挡放电(DBD)甲烷重整制氢的影响。采用正弦、双极和纳秒脉冲电压三种不同脉冲波形的高压电源,脉冲宽度为50 μs ~ 250 ns,电压上升速度为7.6 × 10 ~(4 - 5)× 10 ~(10)V/s。纳秒脉冲制氢的能量效率约为0.9g/kW·h,远高于正弦脉冲和双极性脉冲制氢的能量效率(约为0.5g/kW·h)。这是因为,短脉冲的电压上升速度比正弦波和双极性脉冲的电压上升速度大得多,所以均匀地产生短脉冲的放电。随着脉冲重复频率的增加,氢气产量增加,能量效率略有下降。在0.12 ~ 0.16MPa的范围内,氢气的产生效率与气体压力无关。
The influence of waveforms of the applied voltage on hydrogen production from methane reforming using dielectric barrier discharge (DBD) is investigated. Three types of high voltage power generators with different pulse shape with widths of 50 μs-250 ns and voltage rise speeds of 7.6 × 104-5.2 × 1010V/s of sinusoidal, bipolar pulses, and a nanosecond pulse voltage are used to control the waveform. The energy efficiency for hydrogen production in the case of nanosecond pulse is approximately 0.9 g/kW·h, much higher than those of sinusoidal and bipolar pulses, with approximately 0.5 g/kW·h. This is due to that the voltage rise speed by the short pulse is much higher than those using the sine wave and the bipolar pulse, and so the discharge by the short pulse is uniformly generated. The hydrogen production increases and the energy efficiency decreases slightly with increasing pulse repetition rate. The hydrogen production efficiency is independent of the gas pressure within the ranges from 0.12 to 0.16 MPa.
