This research investigated the volatilization and enrichment of metallic non-metallic elements in municipal solid waste incineration fly ash during thermal treatment. The high-temperature treatment resulted both stabilization heavy metals ash. split depended highly on original speciation. results showed that loosely bound were main contributors to leaching toxicity raw These also easily volatilized. was accompanied by de-chlorination, indicating loss may be related evaporation chloride compounds. On other hand, strongly with less volatile. For six investigated, 42% 58% Cd Pb volatilized at 800 °C. By comparison, volatilizations Cu, Zn, Cr, Ni amounted 18–31% same temperature. remaining became more stable. Stabilization could attributed reactions between decomposition products; thus, new complicated structures, such as Ca3Mg(SiO4)2, Ca2Al2SiO7, CuSiO3, formed. Heavy incorporated into structures stabilized. Moreover, analyses elements, including Mn, Mg, Si, Al. is conducive reusing

There is an urgent need for energy-efficient disposal and resource utilization of the fly ashes from municipal solid waste incineration (MSWI). The low-energy pyrolysis-based detoxification a prerequisite harmless treatment sustainable ashes. In this study, nitrogen-doped hierarchical porous carbon (NHPC) was prepared biomass-derived corn cobs used to enhance low-temperature destruction PCDD/Fs in MSWI ash. On thermal pure nitrogen (referring pyrolysis in) at 350 °C 30 min, removal efficiencies ash based on mass (ηmass) TEQ (ηTEQ) are 87.4% 76.2%, respectively. After 5 wt.% NHPC added ash, ηmass ηTEQ values can be increased 94.9% 90.2%. decomposition inhibit regeneration regulate structural properties optimize chemical environment It eliminate washing process. addition, leaching concentrations heavy metals such as Cu, Zn, Pb Cr experience significant reductions 83.3%, 73.7%, 35.6% 22.9% when pyrolyzed with NHPC. This finding suggests that cannot only facilitate but also immobilizes typical during pyrolysis. anticipated application great energy-saving effect tackle issues within single step.
