The interaction between organic compounds from microalgae and low-rank coal during the co-pyrolysis process was explored via thermogravimetric analyzer combined with an online mass spectrometer. The influence of Glycine (GLE) on thermal behavior and kinetic characteristics from gaseous products generation of mixtures of acid washed low-rank coal (ALC) were investigated. Positive and negative synergistic effects from the pyrolysis parameters and products distribution were observed due to the interaction between GLE and ALC. The addition of GLE promoted the char formation under 75 wt% mixing ratio, with about 24 wt% deviation between the calculated value and experimental value. Negative synergistic effects from yield of CO and CH were found. Kinetic results showed that the order for activation energy was E(H) > E(CH) > E(CO) > E(CO), which was consistent with the releasing sequence.
通过热重分析仪结合在线质谱仪探索了微藻有机化合物与低阶煤在共热解过程中的相互作用。研究了甘氨酸（GLE）对酸洗脱低阶煤（ALC）混合物的热行为和气相产物生成动力学特性的影响。由于 GLE 和 ALC 之间的相互作用，观察到了热解参数和产物分布的正协同和负协同效应。在 75wt%混合比下，GLE 的添加促进了炭的形成，计算值与实验值之间存在约 24wt%的偏差。CO 和 CH 的产率表现出负协同效应。动力学结果表明，活化能的顺序为 E(H)＞E(CH)＞E(CO)＞E(CO)，这与释放顺序一致。
