Liu, Hui;Zhang, Junhui;Liu, Jingyong;Chen, Laiguo;Huang, Hongyi;Evrendilek, Fatih research published 《 Co-pyrolytic mechanisms and products of textile dyeing sludge and durian shell in changing operational conditions》, the research content is summarized as follows. Textile dyeing sludge (TDS) is a highly toxic solid waste whose co-pyrolysis can jointly achieve waste reduction and recovery of value-added products. This study aimed to fill the knowledge gaps about the co-pyrolysis mechanisms and products (gases and solids) and their dynamics in response to the atm. type, blend ratio, heating rate, temperature, and their interactions. The high temperature pyrolysis (>720 °C) in the CO₂ atmosphere appeared as the best option for the waste reduction The (co-)pyrolysis in the CO₂ atmosphere enhanced S-containing air pollutants, CO, and CH₄ but reduced NO_x. The interaction effect between TDS and durian shell (DS) residues promoted the productions of furan and acid compounds and inhibited the productions of aromatic, phenolic, and N-containing compounds The atmosphere type affected the type and strength of the reactions involved in the production of biochars. Our findings provide practical and new insights into the optimization of energy generation, product recovery, and emission control during the (co-)pyrolysis.
