2023年第43卷第1期化工环保ENVIRONMENTALPROTECTIONOFCHEMICALINDUSTRY·79·脉冲电晕低温等离子体协同负载型催化剂降解乙硫醇胡志军，王志良（江苏齐清环境科技有限公司，江苏南京210046）［摘要］采用共沉淀—喷涂法制备了3种负载型催化剂用于协同脉冲电晕低温等离子体降解乙硫醇，采用SEM、TEM、XRD及XPS对其进行了表征，并以污染物降解率和矿化率、能量效率、催化剂工作温度和失活等为评价指标，筛选出最佳催化剂。表征结果显示，负载活性组分后的（γ-Al2O3）0.1/堇青石蜂窝陶瓷粒径更小、孔隙率更高、分布更加均匀。实验结果表明，脉冲电晕等离子体协同Pd0.001/（Ce4La1O9.5）0.03/（Cu5Mn7Zr1O22）0.08/（γ-Al2O3）0.1/堇青石蜂窝陶瓷催化剂降解乙硫醇具有高降解率、高矿化率、高能量利用率以及低有害副产物生成率等优势，同时更低的催化剂工作温度和长时间保持较高催化活性均有利于降低系统能耗和运行成本。［关键词］低温等离子体；负载型催化剂；结构表征；降解；矿化；能量效率；乙硫醇［中图分类号］X742［文献标志码］A［文章编号］1006-1878（2023）01-0079-08［DOI］10.3969/j.issn.1006-1878.2023.01.012Degradationofethylmercaptanbypulsedcoronanon-thermalplasmacombinedwithsupportedcatalystHUZhijun，WANGZhiliang（JiangsuQiqingEnvironmentalScienceandTechnologyCo.Ltd.，Nanjing210046，China）Abstract：Threekindsofsupportedcatalystsforethylmercaptandegradationcombinedwithpulsecoronalowtemperatureplasmawerepreparedbycoprecipitationandsprayingmethod，andwerecharacterizedbySEM，TEM，XRD，andXPS.Takingpollutantdegradationrate，pollutantmineralizationrate，energyefficiency，catalyticworkingtemperatureandcatalystdeactivationastheevaluationindexes，thebestsupportedcatalystwasselected.Thecharacterizationresultsshowthattheactivecomponentsloaded（γ-Al2O3）0.1/cordieritehoneycombceramiccarriertendstohavesmallerparticlesize，higherporosityandmoreuniformdistribution.TheexperimentalresultsshowthatthedegradationofethylmercaptanbypulsedcoronaplasmacombinedwithPd0.001/（Ce4La1O9.5）0.03/（Cu5Mn7Zr1O22）0.08/（γ-Al2O3）0.1/cordieritehoneycombceramiccatalysthastheadvantagesofhighdegradationrate，highmineralizationrate，highenergyutilizationefficiencyan...
