The co-pyrolysis behavior of plastic (PP) with six biomass components (cellulose, hemicellulose, lignin, carbohydrate, lipid, protein) was studied by thermogravimetry. The overlap ratio (OR) and the difference in experimental and theoretical weight loss (ΔW) are defined. The results demonstrated that the interaction of lignin and PP was notable with the OR of 0.9661. From ΔW, it was found that the number of solid residues of hemicellulose-PP and lignin-PP decreased by 1.10% and 2.60%, respectively, which was caused by the hydrogenation reaction between the monomers generated by PP and biochar. The DTG peak shift in co-pyrolysis was further studied. By blending with the biomass, the pyrolysis peaks of PP shifted to the high-temperature region and the value was positively correlated with the fixed carbon content in the biomass components. Kinetic analysis revealed that by co-pyrolysis with biomass, the activation energy of the PP decomposition could be reduced by 39.51% -62.71%.

通过热重法研究了塑料（PP）与六种生物质组分（纤维素，半纤维素，木质素，碳水化合物，脂质，蛋白质）的共热解行为。定义了重叠率（OR）以及实验和理论失重的差异（ΔW）。结果表明，木质素和PP的相互作用显着，OR为0.9661。从ΔW发现，半纤维素-PP和木质素-PP的固体残基数分别减少了1.10％和2.60％，这是由于PP和生物炭产生的单体之间的氢化反应引起的。共热解中的DTG峰位移得到了进一步研究。通过与生物质混合，PP的热解峰移至高温区域，该值与生物质组分中的固定碳含量成正相关。
