摘　　要：使用汽油胶质含量测量方法《燃料胶质含量的测定喷射蒸发法》,扩展测量重芳烃中胶质含量,考察了加热温度以及加热时间对胶质含量测量值的影响,通过多次测量,确定了测量重芳烃胶质含量的实验条件为加热温度180℃,加热时间60min,并使用气质联用仪对可溶性胶质和实际胶质进行族组成分析,可知重芳烃胶质中几乎不含有饱和烃,且芳烃中以三环芳烃为主。Using our country published GB/T 8019-2008 Motor Gasoline and Aviation Fuel-determination of Existent Gum-jet Evaporation Method to measure the gum content of heavy aromatics,the heating temperature and heating time on the yield of gelatin were examined,the experiments conditions were determined as follows： the heating temperature of 180 ℃,the heating time of 60 min,and the group composition of soluble gum and actual gum of heavy aromatics were obtained by gas chromatograph-mass spectrometer.
