The mass loss rate was lower for TDS than BR, with the co-pyrolysis with 50% BR exerting the strongest synergistic effect. The pyrolysis stages 1 (< 400 degrees C) and 2 (400 800 degrees C) were best described using the diffusion and third-order reaction mechanisms, respectively. Activation energy and frequency factor were lower for the pyrolysis of TDS than BR. The addition of no less than 50% BR significantly increased the emissions of CO2, CO, CH4, C=O, and C O and reduced the aromatic compounds. The thermal stability of N-A structure was lower in TDS than BR. The co-pyrolysis with 50% BR significantly inhibited the formations of NH3 and HCN and improved the aromaticity of biochar. This may due to the weakened hydrogenation reaction at N sites, the enhanced conversion of NH3, the inhibition of the ring cleavage in the char-secondary cracking, and the formation of more quaternary-N. Our results provide insights into the co-treatment of TDS and BR, and controls over NO,, precursors for a cleaner energy production.eninfo:eu-repo/semantics/closedAccessTextile Dyeing SludgeBamboo ResiduesSynergistic PyrolysisNOx PrecursorsChar-nitrogen StructuresArticle10.1016/j.jhazmat.2020.123331401326524182-s2.0-85087509797Q1WOS:000581684900048Q1
