城市生活垃圾与园林废弃物的共热解特性
Co-pyrolysis characteristics of municipal solid waste and garden waste
摘要
Abstract
In order to realize the reduction and harmless resource utilization of municipal solid waste (MSW)and garden waste, co-pyrolysis experiment of the waste was carried out by a thermogravimetric analyzer (TGA)and a fixed bed reactor.The effects of different pyrolysis temperature, different proportion of pine and willow on the yield of the pyrolysis products were studied, and the pyrolysis tar was tested using gas chromatography-mass spectrometry (GC-MS).The results showed that the pyrolysis process of MSW, pine and willow can be divided into three stages: dehydration, pyrolysis and carbonization.The maximum weight loss rate of MSW, pine and willow appeared at 321.48, 358.23 and 377.83 ℃ , respectively.During the second stage of the pyrolysis reaction, the DTG curve of the co-pyrolysis of MSW and pine has two precipitation peaks at 342.32 ℃ and 471.48℃ , respectively.And compared with the pyrolysis of MSW, weight rate increased by 7.29％.When the adding amount of MSW, pine and willow was 3 ∶ 1, liquid product of the pyrolysis increased.The content of alcohols,carboxylic acids, aldehydes and other organic compounds containing oxygen in tar decreased and the calorific value increased.The content of oxygen in tar decreased, and pine had greater deoxidation effect on the co-pyrolysis tar, thus the quality of pyrolysis tar had been improved.关键词
