Hydrous treatment of brown coal was investigated to evaluate the effects of treatment time and structural changes. The experiments are carried out in the presence of water in a batch reactor under nitrogen atmosphere at 350℃ for 2-72h. Structural changes occur during the treatment even more than 2h. Brown coal treated for 72h contained less oxygen, more aromatic carbon than that treated for 2h.
