Very high destruction efficiencies for halogenated chemicals have been achieved by plasma pyrolysis. Destruction efficiencies exceeded 99.9999999% for tests with polychlorinated biphenyls (PCBs). Preliminary tests with tetrachloromethane have obtained destruction efficiencies exceeding 99.99%. The plasma pyrolysis process involved the creation of a 250-kW plasma with a temperature in excess of 25 000 degrees C. The toxic material was injected into the plasma zone at a rate between 1 and 2 L/min. Thermochemical and photochemical dissociation of the toxic materials produced atoms and ions which recombined to form primarily H2, CO, HCl, and particulate carbon. The HCl was neutralized by NaOH. The flaring of the H2 and CO should destroy to a high degree any trace residuals. The application of plasma pyrolysis for the ultimate disposal of toxicological waste was also investigated. Rat carcasses containing mean lethal dosage of PCB were pyrolyzed.
通过等离子体热解已实现对卤代化学品的极高销毁效率。对于多氯联苯（PCBs）测试，销毁效率超过99.9999999%。对四氯化碳的初步测试已获得超过99.99%的销毁效率。等离子体热解过程涉及产生温度超过25000摄氏度的250千瓦等离子体。有毒物质以1至2升/分钟的速率注入等离子体区域。有毒物质的热化学和光化学解离产生原子和离子，这些原子和离子重新结合主要形成H2、CO、HCl和颗粒碳。HCl被NaOH中和。H2和CO的燃烧应能高度销毁任何微量残留物。还研究了等离子体热解在毒理学废物最终处置中的应用。对含有平均致死剂量多氯联苯的大鼠尸体进行了热解。
