在磁力搅拌反应器中进行了模拟气流中NaClO溶液同时吸收NO和SO2的实验研究。针对燃煤火电厂烟道气，考察了脱硫剂浓度、反应温度、SO2初始浓度、NaClO溶液初始pH值等操作参数对同时脱除SO2和NO的影响。当温度为313K、NaClO初始浓度为5.8、NaClO浓度为0.01M时，SO2和NO的脱除效率最高，分别为100%和92%。讨论了以NaClO为吸收剂同时脱除SO2和NO的重要速率控制步骤和合适的反应机理。
The experiments were performed in a magnetic stirrer reactor to study the simultaneous absorption of NO and SO2using NaClO solution from simulated gas stream. The effects of various operating parameters viz., absorbent concentration, reaction temperature, initial SO2and NO concentration and initial pH of NaClO solution on simultaneous removal of SO2and NO were investigated in regard to coal-fired thermal power plant stack gases. The maximum removal efficiencies of SO2and NO were observed as 100% and 92%, respectively at 313K, initial NaClO solution pH 5.8 and 0.01M NaClO concentration. The important rate governing steps with appropriate reaction mechanisms for simultaneous removal of SO2and NO using NaClO as absorbent were also discussed.
