垃圾衍生燃料掺混污泥共热解特性及动力学分析
Co-pyrolysis characteristics and kinetic analysis of refuse derived fuel (RDF) blends sludge
摘要
Abstract
In this paper,the reaction kinetic and gas product characteristics of pyrolysis of refuse derived fuel (RDF),sludge and their mixture were studied by using thermogravimetric analysis-Fourier transform infrared spectrometer (TG-FTIR).The results showed that there was synergistic effect in the co-pyrolysis process of sludge and RDF.When the proportion of sludge is 50％,the whole pyrolysis process presented promotion effect,and the effect is the most obvious at the temperature range from 500℃ to 1000℃.The Coats-Redfern method was used to analyze the kinetic parameters of the pyrolysis process.The results indicated that the co-pyrolysis reaction of RDF and sludge in the low temperature stage (240-380℃) and high temperature stage (670-740℃) conforms to the second-order reaction law,while meets the first-order reaction law in the middle temperature stage (430-540℃).Compared with RDF pyrolysis,the activation energy of co-pyrolysis of RDF and sludge decreased obviously,which indicated that co-pyrolysis could promote the pyrolysis reaction process.FTIR analysis showed that the co-pyrolysis of RDF and sludge has little effect on the precipitation of CO2 and CO,but promotes the production of CH4.Meanwhile,the co-pyrolysis results in an increase in the precipitation ofHC1,NH3 and HCN as well.The results of this study could provide data support for the development and design of the co-pyrolysis process of RDF and sludge.关键词
