系统聚类法在减压馏分分类中的应用

Application of Hierarchical Cluster in Classification of VGO

采用气相色谱/质谱(GC-MS)对102种国内直馏减压馏分油进行定性定量分析,将22种组成数据作为聚类指标,利用聚类分析方法,对102种国内直馏减压馏分油进行分子组成相似性分类,结果表明:102种直馏VGO可分为6类。将减压馏分油进行合理分类,可为VGO实际加工确定合适的加工方案提供了理论依据。

102 domestic straight-run VGOs were analyzed qualitatively and quantitatively by GC-MS. Twenty-two kinds of composition data were used as clustering indicators and 102 domestic straight-run VGOs were classified by cluster analysis method. Oils were classified by molecular composition similarity. The results showed that 102 straight-run VGOs can be divided into 6 categories. The rational classification of VGO can provide a theoretical basis for determining the appropriate processing scheme for VGO actual processing.
