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）对中间相沥青碳纤维进行了表征，求得了结构参数。并研究了碳化过程中，结构、性能与温度的依存关系。Spinnable mesophase pitch was prepared ftom catalytic cracking residus of petroleum and uniform mesophase pitch carbon fibre (MPPCF) was obtained. The optimal oaldation condition was determined by thermal analysis and elememtal analysis. MPPCFwas characterired by X - ray difftaction (XRD) and transmission electron microscopy (TEM) and structure parameters were investigated. The dependence of structure properties on temperature during carbonization were studied.
