The influence factors of dielectric barrier discharge plasma to production of syngas derived from H2S-CO2 acid gas

  • 摘要: H2S和CO2两种有害酸性废气常共存于煤化工、天然气化工及石油化工等重要化工生产中,造成了工业设备及管线腐蚀,必须就地进行无害化处理。采用介质阻挡放电等离子体催化实现一步转化H2S-CO2混合酸气制合成气,将具有强腐蚀性、毒性的H2S和温室气体CO2无害化,又产出合成气,完成了以废治废的酸性废气资源化再利用。研究了用于H2S-CO2一步转化制合成气的介质阻挡放电等离子体反应各参数对转化反应的影响,进行了不同参数的对比研究,考察并揭示了比能量密度(SEI)、放电结构、放电频率、放电间隙以及放电区域长度等与H2S-CO2转化制合成气反应性能的内在关联。在此基础上设计并构建了多管并联介质阻挡放电等离子体反应系统。

     

    Abstract: H2S and CO2, two harmful acid waste gases, often co-exist in important chemical production such as coal-chemical industry, natural gas chemical industry and petrochemical industry, causing corrosion of industrial equipment and pipelines, and must be treated innocuously. Co-conversion of H2S-CO2 mixed acid gas to syngas has been carried out using dielectric barrier discharge (DBD) plasma-catalysis, which renders the highly corrosive and toxic H2S and greenhouse gas CO2 harmless, and produces syngas. The effects of various parameters of the DBD plasma on the reaction of one-step conversion of H2S-CO2 to syngas were studied. Moreover, a comparative study of the different parameters of DBD plasma was carried out. The intrinsic correlation between the reaction performance of syngas production via H2S-CO2 conversion and these parameters, including specific energy input (SEI), discharge shape, discharge frequency, discharge gap and discharge length, was investigated and revealed. On this basis, a multi-tube parallel DBD plasma reaction system was designed and constructed.
