Coal Structure an overview ScienceDirect Topics

In Environmental Impacts of Coal Mining & Utilization, 1987. 3.1.1. Chemical structure of coal. Direct liquefaction of coal involves hydrogenation in the presence of hydrogen donor solvents and molecular hydrogen at high pressure and relatively low temperature. The hydrogenation mechanisms depend on the chemical structure of coal.
