【摘要】 选用氮磷化合物作为制备炭纤维的催化剂,通过热重、差热和红外等手段分析了其对粘胶纤维在空气气氛下热解过程的影响,并初步探讨了相关催化机理。结果显示,加入氮磷催化剂能降低裂解反应起始温度,并提高热解收率。更多还原

【Abstract】 The pyrolysis behavior of viscose fibres treated with P and PN has been investigated by thermogravimetry-mass spectrometry (TG),DSC and IR analysis in air atmosphere. It was found that the addition of P or PN resulted in the lower pyrolysis temperature of viscose fibres and the lower conversion of levoglucosan. So a higher yield of carbon was gotten.更多还原
