Mo-catalysed hydrogenation processes of four coals, ranked between lignite B and high volatile bituminous coals, are studied. Ammonium heptamolybdate was used as a catalyst precursor. Hydrogenations were carried out at 300, 350 and 400 o C at a hydrogen pressure of 10 MPa, with reaction times ranging from 5 to 30 min. The maximum rate of the process, related to the textural characteristics...
