Summary: The current study used non-isothermal thermogravimetric analysis to analyze the thermal degradation behavior of water hyacinth and determine the kinetic parameters. Approximately 80% thermal degradation of water hyacinth occurred in three temperature phases from 30 to 900 degrees C. The activation energy of feedstock breakdown was calculated using four different model-free approaches, and the mean values ranged from 251.33 to 298.48 kJ/mol within the conversion band of 0.15-0.75. The characterization and kinetic analyses of biomass revealed its potential as pyrolysis feedstock.

Summary: The co-combustion of textile dyeing sludge (TDS) and cattle manure (CM) can enhance resource circularity and pollution control. However, the migration and transformation behaviors of ashes during this process are still unclear. This study used thermogravimetric experiments and thermodynamic simulations to investigate the transformation and migration of co-combustion ashes and the interactions involved. The addition of TDS increased the environmental safety of Ni and Cr by transforming them from extractable form to stable form. P dominated S in the reaction with Ca, promoting the emission of S-containing gases and the generation of apatite P. The reactions between minerals in CM and Ca in TDS resulted in the formation of calcium silicate, reducing the S-fixation ability of Ca and increasing the emission of S-containing gases. These findings provide insights into the interactions among minerals, heavy metals, and specific elements, and their impact on pollutant emissions, thus enhancing pollution control strategies.
