摘　　要：以石油系催化裂化渣油为原料，调制出可纺性的中间相沥青，并纺出均匀的中间相沥青纤维。用热分析法和元素分析法，确定了最佳氧化条件。利用X-射线衍射技术（XRD）及透射电镜（TEM）对中间相沥青炭纤维进行了表征，求得了结构参数、并研究了炭化过程中，结构、性能与温度的依存关系。Spinnable mesophase pitch was prepared from catalytic cracking residue of petroleum and uniform mesophase pitch carbon fibre (MPPCF) was obtained. The optimal oxidation condition was determined by thermol analysis and elemental analysis. MPPCF was characterized by X-ray difftaction (XRD) and transmission electron microscopy (TEM )and structure parameters were investigated. The variation of structure, properties and temperature during carbonization were studied.
