【摘要】 <正> 煤液化产品无论是用于制造液体燃料、提供化工原料,还是做为煤液化溶剂,都需要了解它的化学组分。在这方面毛细管气相色谱(GC)及质谱技术具有优越的功能。煤液化油沸程宽,结构类型复杂,组分繁多,单独使用GC或MS技术不可避免峰重叠和非同系物的质量重叠问题,难以得到较好的分析结果。GC/MS联用技术在缺少标样更多还原

【Abstract】 The coal derived medium oil was separated by HPLC with an NH2 column and the hydrocarbon fractions of the oil were characterized by GC-MS. The results of the individual components of the oil were obtained.更多还原
