Abstract
Recently, the momentum of the decarbonization movement has been rapidly growing. Pyrolysis gasification technology is attracting attention as one of the technologies that contribute to carbon neutrality and offer expanded options for the efficient generation of electricity using gas engines and chemical recycling, in contrast to current incineration. In this study, the characteristics of pyrolysis gasification of municipal solid waste were investigated using actual waste samples obtained from an incineration facility. By following the procedure outlined in Kansei No.95, a method was discovered to adjust waste samples that are representative even in small amounts for each component. Thermal analysis was conducted on these samples, which were categorized into biomass and plastic. The results showed rapid weight loss within different temperature ranges, allowing for the definition of their respective pyrolysis temperatures ranges. Furthermore, qualitative analysis using Py-GC/MS was performed to examine the main products of pyrolysis, revealing their similarity differs by components. Additionally, the heterogeneity of the municipal solid waste composition suggested that it might derive from fabric and kitchen waste, rather than paper or wood.
