The technique of pyrolysis-hydrogenation-gas chromatography (PHGC: McHugh et al., 1976, 1978) provides a convenient means of analysing the carbon-skeleton structures of coals and coal-derived kerogens. Catalytic hydrogenation of the pyrolysate has the advantage of simplifying its composition prior to analysis by GC (or gas chromatography-mass spectrometry, GC-MS) without significantly diminishing the amount of structural information available in the resulting pyrogram. Alkenes and heteroatomic compounds are converted to the corresponding alkane or aromatic hydrocarbon. In the present study we extend the application of PHGC to kerogens of microbial origin, i.e., insoluble sedimentary organic matter derived from algae and bacteria.
