摘要：

In order to clarify the pyrolysis characteristics of actual paper mill solid waste under the real component ratio and the influence of the synergistic effects between the components on its pyrolysis behavior, the real ratio of the components of the actual paper mill solid waste was determined by manual sorting. Besides, combined with DG-DAEM kinetic analysis, TG-FTIR and Py-GC/MS experiment were performed to systematically investigate the influence mechanism of the synergistic effects between the components on its pyrolysis behavior and the distribution of main pyrolysis products of paper mill solid waste. The results showed that the synergistic effects of its components had a significant impact on the pyrolysis process of actual paper mill solid waste. The synergistic effects of the components were not only conducive to the release of volatiles in the pyrolysis process of paper mill solid waste, but also could effectively promote the generation of small molecules like CH4. Further kinetic analysis showed that the degradation reaction was dominant during the pyrolysis process of mixture sample of paper mill solid waste. In addition, at different temperatures, the experimental value of the relative content of hydrocarbons in the main liquid pyrolysis product distribution of the mixture sample was always higher than its theoretical value, while the experimental value of the relative content of the total oxygen-containing components was always lower than its theoretical value. The synergistic effect between the components of the mixed sample is beneficial to the deoxygenation of oxygen-containing components in the pyrolysis product and the conversion to hydrocarbon products. © 2022, Editorial Board of CIESC Journal.
