Simulation distillation by comprehensive two-dimensional gas chromatography |
摘要 |
A method to simulate distillation of a petroleum stream by comprehensive two-dimensional gas chromatography including the step of separating said petroleum stream with a two-dimensional gas chromatograph to determine polarity as a function of temperature, and integrating vertically the two-dimensional gas chromatograph at a given temperature to determine signal intensity as a function of temperature. |

1. A method to simulate distillation of a petroleum sample by comprehensive two-dimensional gas chromatography with sub-total yield of compounds in the sample by class as a function of boiling point, comprising:
a) separating said petroleum stream with a two-dimensional gas chromatograph in a first non-polar dimension of retention time to define component boiling point and a second dimension of polarity with detection of components by polarity class to determine presence of components by relative mole as a function of temperature, b) integrating the two-dimensional gas chromatograph at a given temperature to determine the relative molar amount of separated components by class as a function of temperature, wherein said integrating step gives the mole percent of non-carbon elements containing compounds in the sample. |
