处理挥发性有机废气的几种典型吸附技术

王溪睿110031：来源于化工、医药、汽车领域的挥发性有机废气（VolatileOrganicCompounds，VOC）是一种常见的空气污染物质，也是造成光化学烟雾的因素之一。近年来各国对VOC的排放政策都越来越严格。VOC的处理方法常见的有吸附法、热力燃烧法等，其中吸附法由于无二次污染、处理效率高而得以普遍应用。对于不同类型的VOC废气，采用吸附法处理时需要对吸附技术进行改进后再应用到实际，针对于此总结了处理不同类型VOC废气的吸附技术。挥发性有机气体，吸附法，废气处理AbstractVolatileOrganicCompoundsVOCisamongacommonairpollutantsemittedfromchemical,pharmaceuticalsindustryandvehiclefield,besides,it’salsoakeyfactorthatleadtophotochemicalsmog.ThegovernmentsofvariouscountriesalsoformulatestrictregulationstorestricttheemissionofVOC.TherearemanymethodstocontrolVOC,suchasabsorption,thermaloxidation.Betweenthemtheabsorptionmethodiswidelyusedasitsadvantagesofnosecondarypollutionandhighremovalefficiencyoverothertechniques.However,asthedifferenttypesofVOC,thereneedcorre-spondingabsorptionmethodtocontrolthem.Inviewofthat,thepaperlistedsomedifferentabsorptiontechniqueswhichusedincontrollingdifferentVOC.Keywordsvolatileorganiccompounds;absorptionmethod;gastreatmentX701.7A1674-1021201408-0042-032014－05－042014-08-04。1988。1。VOC、、1-2。VOC、。VOC、、。VOC。VOC3VOC、、VOCVOCVOC。VOCVOC。VOC、。VOCVOC。22.1VOC4。42。VOC。VOCVOC。2.2VOC。oxygen-containing、carbon-based、polymer-based5。、Zeolite、。。1。2.3、、6。7。、。1。。130℃。3VOC。VOC。。3.1TSATemperature-SwingAbsorption,TSA。、。。、。。3.2PSA2080VOCPressure-SwingAbsorption208。VOC。、。1/m2·g-1/cm2·g-1/kg·m-31000~15000.5~0.8300~400＞1000.3~0.4300~400600~8000.3~0.45700~800500~10000.25~0.4600~900143、。、VOC。、、。3.3SMBA1961BroughtonSim-ulatedMovingBed,SMB。。、。—。3.4VOC。VOC、、、、Dolidovich9VOC。4、、、。。VOCVOCVOC。、VOCVOC。。1.J.20034547-51.2.VOCJ.2008143-5.3.J.201331850-51.4.M.2001.5.J.1993214-17.6.J.199974.7.J.2000165392-399.8.J.20022031-4.9.—J.20134307-313.44（上接41页）1.D.2011.2.J.200720427-28.3.J.2009234325-328.4.J.200619417-19.5.J.2013332319-327.
