蒸汽等离子体射流(SPJ)是将苯酚水溶液作为等离子体形成气体引入水等离子体炬中，注入苯酚水溶液中进行氧化降解水溶液中的有机污染物。实验结果表明，苯酚不仅在SPJ中被降解，而且由于高浓度的羟基自由基，在苯酚水溶液中也被降解。当苯酚初始浓度从0.5g·L−1增加到50.0g·L−1时，能量效率从(1.6~1.8)×10−1增加到(4.8~8.0)×10−·J−1。苯酚分解的主要中间产物是邻苯二酚、对苯二酚、马来酸、丁二酸和肉豆酸。气态流出的主要产物是H2、CO和CO2。
Steam plasma jet (SPJ) was generated by phenol aqueous solution introduced into water plasma torch as plasma forming gas, which injected into phenol aqueous solution to conduct oxidation degradation of organic pollutants in aqueous solutions. The experimental results indicated that the phenol was not only decomposed in SPJ, but also degraded in phenol aqueous solution due to high concentration hydroxyl radicals. Moreover, the energy efficiencies significantly increased from (1.6–1.8) × 10−10 to (4.8–8.0) × 10−8 mol · J−1 with the initial concentration of phenol increased from 0.5 to 50.0 g · L−1. The main intermediates of phenol decomposition were pyrocatechol, hydroquinone, maleic acid, butanedioic acid, and muconic acid in liquid. The major gaseous effluence products were H2, CO, and CO2.
