添加CaO对生物质热解 焦油生成的影响研究 潘春鹏，陈 种，黄群星，池 涌 浙江大学能源清洁利用国家重点实验室，浙江杭州 310027 [摘 要] 焦油生成的影响，并与干纸浆的试验结果进行对照。结果表明，焦油主要成分为酮、醛、 酸、酚与烃类物质；添加CaO能显著减少焦油含量，添加比例越大其催化裂解效果越 好；加热速率增大不利于减少焦油生成；800℃下竹子在管式炉热解，添加Ca0极大地 促进了H。的生成，而CO：与CO含量降低；随着CaO添加比例的提高，产气热值、产气 率、焦炭产量随之提高；CaO／M质量比为2时相对于未添加CaO的情况下，产气热值 和产气率相应提高了33．0％和27．7％。 [关 键 词] 生物质；TG—FTIR联用技术；CaO；催化热解；焦油；焦炭 [中图分类号]X705 [文献标识码]A [文章编号]1002—3364(2012)08—0018—06 EDOI编号]10．3969／j．issn．1002—3364．2012．08．018 EXPERIMENTALSTUDYoNINFLUENCEoFCaOADDITIONON TARGENERATIoNDURINGBIoMASSPYRALYSIS PAN Chunpeng，CHEN Chong，HUANGQunxing，CHIYong State ofClean Province，China KeyLaboratoryEnergyUtilization，ZhejiangUniversity，Hangzhou310027，Zhejiang Abstract：BasedonTG—FTIRcombined ofdifferent technology，influence and ratesontar and ofbamboo was heating generationduringpyrolysis drypulp show taris of and CaO that，the mainlycomposedketone，aldehyde，acid，phenol can reducethetar themoreaddition better dramatically content，and proportion，thecatalyticcracking of the rate hasbadeffecton thetar ofham— tar；increasingheating reducinggeneration．Thepyrolysis boointubefurnaceat theformation 800℃indicatethat，theCaOadditivecan of extremelypromote
