Lagging and Its Kinetic Mechanism of Hydrocarbon Re-generation from Organic Matters in Coals

摘要

Based on the composite analysis of the coal sample series with natural and artificial matura- tion, the lagging and its kinetic mechanism of the hydrocarbon re-generation from the organic mat- ters in coals were studied using the Rock-Eval gas chromatogram (Py-GC) method. The results show that the maturation at the hydrocarbon re-generation peak shifts regularly forward with in- creasing the starting maturation and the deadline of the hydrocarbon re-generation lies about at 4.0/100 R_0.
