Abstract
In this paper, source rocks from major Chinese coal-bearing petroliferous basins were studied by Pyrolysis-Gas Chromatography (PY-GC) technique, and compositional characters of pyrolysates and their significance were discussed in detail. Differences in pyrolysate compositions of different coal-bearing source rocks are principally reflected upon the abstract amounts of C+5 n-alkanes and n-alkenes, as well as upon the constitutinn of aromatic compounds. We selected C1-C5, C6-C14 and C+15 n-alkanes and n-alkenes as three terminal represents of pyrolysate composition, and their relative amounts could be effectivelly employed to distinct types and features of hydrocarbon generation in coal-bearing source rocks.All the results show that PY-GC technique is an effective approach for coal-generated hydrocarbon evaluation, and this technique is worthy of widespread application.
