摘要
研究了乙烯焦油沥青、乙烯焦油沥青的沥青烯组分和催化改质乙烯焦油沥青在炭化过程中生成中间相沥青的动力学和显微结构的变化。采用溶剂抽提法、元素分析法、VPO平均分子量测定法、H—NMR和IR光谱法测定了几种ETP和中间相沥青的结构参数。
This paper deals with the kinetics of mesophase pitch formation during the carbonization of ethylene tar pitch(ETP), asphaltene formation of ETP and catalaytically modified ETP and their microscopic structures. Solvent extraction, elemental analysis, molecular weight determination by VPO, ~′H—NMP and TIR spectroscopy were accomplished for the estimation of structural parameters of ETP precursors and mesophase pitches.
