  • 摘要: 选择废弃棉纤维和粘胶纤维两种纺织纤维作为水热炭化原料,并以微晶纤维素为模型底物进行对比,研究原料结构对水热炭化条件及产物的影响。结果表明,高结晶度的棉纤维(60.35%)和微晶纤维素(60.24%)制备炭微球的最佳条件分别是330℃,6 h,0.15% CuSO4和310℃,6 h,0.10% CuSO4,而低结晶度(34.31%)的粘胶纤维的最佳条件为260℃,8 h。结晶度越低,水热炭化条件越温和,而聚合度对其影响不显著。采用SEM、XRD、FTIR、TG和EDS对炭化产物进行表征,结果表明,不同原料合成的炭微球具有类似的无定型结构和丰富的官能团,但棉纤维和微晶纤维素合成的炭微球具有更高的碳含量和热稳定性,这可能是更高的水热炭化温度所致。因此,纤维素结晶度是影响其水热炭化合成炭微球的重要因素。
