Pyrolysis kinetics of cornstalk (CS), bamboo fiber powder (BFP) and their blends with anthracite (AN) was investigated by differential isoconversional method. The role of AN additive was different in blending with different biomasses, which decreased the activation energy of CS, but increased that of BFP. Deconvolution by Fraser-Suzuki function resolved the overlapped rate curves into three independent pseudo components with high accuracy, improving the correlation coefficients and reasonable conversion ranges for isoconversional kinetics. The influences of AN additive on the activation energy of pseudo components agreed with those observed in overall kinetic parameters, which was probably attributed to thermal diffusivity, bringing positive or negative synergy depending on the thermal properties of biomass. Most of the changes were distributed in pseudo hemicellulose and lignin, and further increased along with the pyrolysis process. Reproduction of rate curves was realized based on obtained kinetic parameters, which validated that the kinetic analyses were high-quality.

采用微分同转化法研究了玉米秸秆，竹纤维粉及其与无烟煤的共混物的热解动力学。在与不同生物量混合时，AN添加剂的作用不同，这降低了CS的活化能，但增加了BFP的活化能。用Fraser-Suzuki函数进行反卷积可以将重叠的速率曲线高精度地分解为三个独立的伪分量，从而提高了相关系数和合理的等转化动力学范围。AN添加剂对假组分活化能的影响与在整体动力学参数中观察到的一致，这可能归因于热扩散率，根据生物质的热特性带来正或负协同作用。大部分变化分布在假半纤维素和木质素中，并且随着热解过程进一步增加。基于所获得的动力学参数实现了速率曲线的再现，这证明了动力学分析是高质量的。
