摘　　要：毫秒炉裂解气经二级冰水冷却分为气相和液相 ,采用毛细管气相色谱对裂解气相和液相中的组分进行分离、定性、定量 ,通过计算得到热裂解产物中各组分的质量分数、摩尔分数以及重均分子质量、数均分子质量。对乙烯装置石油热裂解气中的组分进行连续 5天的分析 。The components in the gas and the liquid of pyrolysis products were separated,qualitatively and quantitatively analyzed by capillary gas chromatography.The mass fraction,molar fraction and relative molecular mass were calculated.The results showed that the pyrolysis process was steady by the analysis of five days.

关 键 词：毛细管气相色谱 热裂解产物 组成 相对分子质量
