摘要
用气相色谱以程序升温方式分析了裂化汽油,并将各组分程序升温保留时间转换为恒温保留指数。以各组分在OV-1和SE-54固定相上,同一柱温下的保留指数差及在各柱上的温度系数为三因素进行斜交因子分析和本征矢量旋转,给出了裂化汽油样品的PONA值,经色谱-质谱仪分析验证了结果的正确性,为裂化汽油样品的PONA分析提供了一种新方法。
A catalytic cracking gasoline was analyzed by temperature-programmed gas chromatography with capillary columns.Retention times of each constituent in the gasoline under temperature-programming conditions were transformed to constant-temperature retention indices.The differences between the retention indices of the constituents on two stationary phases OV-1 and SE-54 at the same temperature and their temperature coefficients on each column were processed with Promax oblique rotation factor analysis and eigenvector rotation.The constituents in the gasoline were classified into paraffins(P),olines(O),naphthenes(N) and aromatics(A) with the above method.The correctness of which was fully proved by gas chromatography-mass spectrometry.
