    Abstract
  • The authors correlated the compositions of pyrolytic products between the coal-as-phaltenes and the coals of different coal-ranks (Rmax°0.43-1.80%), by means of PY-GC. The study shows that the pyrolytic products of the coals are generally similar to those of the coal-asphaltenes. Furthermore, in view of the changeable features of n-alkanes observed from different carbon number intervals at the different stages of thermal evolution, it may be clear that coal asphaltenes had contributed to various extents at the different stages of their evolution.
