本文采用热重分析（TGA）、热重-红外光谱（TG-FTIR）和热重-质谱（TG-MS）等方法研究了杜氏盐藻（Dunaliella tertiolecta）与聚丙烯（PP）的共热解动力学。热重分析结果表明，一定粒径的PP加速了微藻的热解过程，而D.三倍体均大于PP。当PP和D的质量比为0.05时，这种交互作用达到最大.第三脑室扩张6：4。由FWO动力学模型估算的活化能也支持这种相互作用。TG-FTIR和TG-MS结果表明，PP和D处CO2含量显著降低。PP释放的小分子（如自由基）可能与D.微藻中的叔支链或羰基。
In the current work, the co-pyrolysis kinetics ofDunaliella tertiolectaand PP were investigated via TGA, while TG–FTIR and TG–MS were used for the analysis of gas-phase components and volatiles transition. The TGA results show that PP with certain small particle size accelerates the pyrolysis process of the microalgae, while the existence ofD. tertiolectadelayed that of PP. This significant interaction achieves maximum when mass ratio of PP andD. tertiolectais 6:4. The activation energy estimated from FWO kinetic model also supports this interaction. The TG–FTIR and TG–MS results show that a significant decrease of CO2occurs at PP andD. tertiolectamass ratio of 6:4, indicating that small molecules (such as radicals) released by PP might react with CO2produced byD. tertiolectaor carbonyl groups in the microalgae.
