| Outline of Final Research Achievements |
In this study, we investigated two-step process for converting low-rank coal into high-rank coal and recovering aromatic compounds. Regarding to the upgrading of low-rank coal (1st step), non-polar solvent such as toluene was found to be appropriate for co-solvent of water. We examined the effect of reaction conditions and succeeded in producing bituminous-like coal with a high yield at 350 degree C for 2 hour. Next, brown coal-derived organic phase was employed in the reaction over iron oxide-based catalyst. Depolymerization of brown coal-derived compounds proceeded, and aromatic compounds increased after the reaction. Moreover, this process was applied to peat under optimal conditions, resulting in the conversion into sub-bituminous-like coal.
