中文摘要：

选取木薯茎作为与生活垃圾共热解的试验物料,采用热重分析（TG-DTG）、动力学分析、红外分析（FTIR）等方法,研究不同比例木薯茎对生活垃圾热解产物的影响、最佳添加量及协同作用。结果表明：热解主要分为脱水、热解和炭化3个阶段,生活垃圾与木薯茎混合共热解的温度区间主要在200~550℃;生活垃圾、木薯茎及20%木薯茎与生活垃圾混合的热解活化能分别为50.72、37.72及43.36 k J/mol,添加一定量的木薯茎可以降低生活垃圾热解的表观活化能,并对生活垃圾的热解具有一定的促进作用;木薯茎最佳添加量为20%,热解液的产率提高了6.24%;与生活垃圾单独热解相比,添加20%木薯茎的共热解油中羧酸、醇、酚的含量有所减少,有利于脱氧、脱酸,提高热解油的热值,增加热解液的有机物种类与数量。

英文摘要：

Laboratory experiment of co-pyrolysis was conducted using certain amount of cassava stems as test material added to municipal solid waste（MSW）,investigating the effects of cassava stems on pyrolysis of MSW by thermal gravity analysis（TG-DTG）,dynamic analysis and FTIR. Findings of the experimental study suggested that pyrolysis was mainly divided into three stages,i.e.,dehydrated,pyrolysis and charring;the co-pyrolysis temperature ranged from 200 to 550 ℃;and the activation energies of MSW,cassava stems and mixture of 20% cassava stems and MSW were 50.72 k J/mol,37.72 k J/mol and 43.36 k J/mol respectively. Thus,adding a certain amount of cassava stems could reduce the apparent activation energy in the pyrolysis of MSW promoting the pyrolysis effect,and with the amount of 20% cassava stems added,the yield of pyrolysis liquid increased by 6.24%. Contrasted with the pyrolysis of sole MSW,addition of cassava stems（20%） led to reduction of the content of carboxylic acid,alcohol and phenol in the co-pyrolysis oil,which was conducive to removing oxygen and acid,strengthening the heating value of pyrolysis oil,and increasing the type and quantity of organic matters in pyrolysis liquid.
