一种用二维气相(裂解)色谱-质谱联用法对煤炭中挥发性物质组分进行分类的分析方法

  Molecular composition of coal is important to interpret characteristics of coal,depositional environment and occurrence of coal,predict coal industrial utilization,and control pollutant discharge during coal utilization.However,due to complexity mixture of coal with hundreds and thousands chemicals of coal pyrolysis products,group classification analysis could be adapted to reducing the dimension of chemicals of coal pyrolysis products by comprehensive two-dimensional Gas-Chromatography Mass-Spectrometry(GC×GC-MS)coupled with an online fixed furnace.Through group classification analysis,the most chemicals of coal pyrolysis products divided into ten molecular groups by the separation of GC×GC and identification of MS,which could interpret the molecular composition of coal pyrolysis products and the relationships with depositional environment and occurrence of coal by Hierarchical Cluster Analysis(HCA)and Principal Components Analysis(PCA),and provide the molecular evidence for the reasons of different conditions of coal direct liquefaction.
