The solvolysis of coals represent an important way to access to coal structure, in relation to his utilization in carbonization, liquefaction or gazeification. The aim of our work was locussed on coal solvolysis and characterization of the solvolysis products obtained from coals and macerals. The N-methyl 2 Pyrrolidinone (NMP) extraction, which is a physical process of solvolysis and the solubilization by the mixture methanol/sodium hydroxide (MeOH/NaOH) were realized to study the molecular structure of coal. Coal was considered in the frame of this study, as a three-dimensional crosslinked network or "macromolecular phase" (MM), which trapped free molecules that are not covalenty bonded to the network and constituated the molecular phase (...
