The removal of CS2 by a wire-in-tube pulsed corona reactor was experimentally investigated. The effects of O2 and H2 in Ar gas on the removal of CS2 were examined. It was shown that the removal of CS2 increased with the increase of input pulse voltage. The decomposition of CS2 was improved in the presence of O2 in gas stream and the maximal removal was over 97%. The main gaseous products of CS2 decomposition with the addition of O2 in Ar gas were CO, CO2 COS and SO2, while, with the presence of H2 in Ar gas, the main products of CS2 decomposition were H2S and CH4. It was found that with the co-existence of sorbent Ca(OH)2 in the reactor, the gaseous products of CS2 decomposition (SO2 and H2S) were not detected, showing that the products were absorbed by the sorbent Ca(OH)2. It was also found that the removal of CS2 decreased when there was water vapor in gas stream.
对丝管式脉冲电晕反应器去除二硫化碳(CS₂)进行了实验研究。考察了氩气中氧气(O₂)和氢气(H₂)对CS₂去除效果的影响。结果表明,CS₂的去除率随输入脉冲电压的升高而增加。气流中存在O₂时,CS₂的分解得到改善,最大去除率超过97%。在氩气中添加O₂时,CS₂分解的主要气态产物为一氧化碳(CO)、二氧化碳(CO₂)、羰基硫(COS)和二氧化硫(SO₂);而在氩气中存在H₂时,CS₂分解的主要产物为硫化氢(H₂S)和甲烷(CH₄)。研究发现,反应器中存在吸附剂氢氧化钙(Ca(OH)₂)时,未检测到CS₂分解的气态产物(SO₂和H₂S),表明产物被吸附剂Ca(OH)₂吸收。还发现气流中存在水蒸气时,CS₂的去除率降低。
