摘要：

Benzene polycarboxylic acids formed upon oxidative degradation of the macromolecular network of a set of French coals with ruthenium tetroxide are proposed as the basis of new coal rank indices. Their distribution probably reflects the degree of condensation of the polyaromatic subunits occurring in the network of the coals. This features is illustrated in the case of the benzene tetracarboxylic acids. Application of these molecular indices to Gondwana coals, as well as to maceral concentrates indicates that they are also type related. They could prove particularly useful in the case of coals or kerogens having undergone secondary alteration processes.
