SIMPLIFICATION OF PYROLYSIS—GAS CHROMATOGRAPHY PARAMETERS FOR KEROGENS AND ITS SIGNIFICANCE

In order to determine PY-GC parameters of kerogen,certain compounds are selected to replace the other similar compounds.The results show that these parameters may after all be of geochemical significance and practice.Moreover,the difficulties in spectrogram determination and the calculation of the parameters are greatly reduced,which would be useful to the application of PY-GC analysis technique.
