市政污泥与废塑料共热解特性及动力学研究
Research on co-pyrolysis characteristics and kinetics of municipal sludge and waste plastics
摘要
Abstract
This study employed municipal sludge(MS),polypropylene(PP),and polyethylene terephthalate(PET)as feedstocks to investigate the effects of plastic co-feeding on the pyrolysis characteristics and product distribution of MS.The mass changes and kinetic properties associated with the co-pyrolysis of MS/PP and MS/PET blends were obtained by thermogravimetric analysis coupled with the Coats-Redfern integral method.Additionally,the compositions of the resulting co-pyrolysis products were analyzed by pyrolysis-gas chromatography/mass spectrometry(Py-GC/MS).The results indicated that the synergistic effects observed during the co-pyrolysis of MS/PP and MS/PET shifted the pyrolysis process toward lower temperatures and enhanced the overall conversion efficiency.The apparent activation energy required for the co-pyrolysis of both MS/PP and MS/PET blends was lower than that for MS mono-pyrolysis.Moreover,the addition of PP and PET led to a more pronounced reduction in the apparent activation energy associated with the pyrolysis of heavy molecular-weight species in the high-temperature region.Compared to the mono-pyrolysis of MS,co-pyrolysis of MS/PP increased the relative contents of C30+organics and aliphatic hydrocarbons,whereas co-pyrolysis of MS/PET not only primarily enhanced the relative yield of C10～C15 products,but also increased the relative contents of alcohols,aliphatic and aromatic hydrocarbons.关键词
