摘　　要：建立了废塑料热解油的固相萃取前处理方法,使用硅胶、负载银-氧化铝的双固相萃取柱分离得到饱和烃、烯烃和芳烃组分,并分别进行气相色谱分析和质谱分析;根据沸点与保留时间的关系,将得到的气相色谱图与总离子流色谱图划分为柴油馏分和蜡油馏分(VGO),结合气相色谱和质谱数据可得到柴油和VGO馏分的烃类组成,实现了宽沸点废塑料热解油中柴油及VGO馏分的烃类组成分析.A pretreatment method of solid phase extraction for pyrolysis oil from waste plastics was developed.The pyrolysis oil was separated into saturates,olefins and aromatics by double solid phase extraction column which was made up of silica gel and silver-aluminium oxide,and then they were analyzed by GC-MS-FID.According to the relationship of boiling points and retention time,the obtained gas chromatogram and total ion chromatogram(TIC)of the compounds were divided to diesel and vacuum gas oil(VGO)distillates,and the hydrocarbon compositions of diesel and VGO fractions were obtained by combining gas chromatogram and mass spectra.The hydrocarbon composition of diesel and VGO fraction in pyrolysis oil with wide boiling point was analyzed.
