| titleOfInvention | Ashless coal production method |
| abstract | In the production of the ashless carbon, it is preferable to use a solvent having a two-ring aromatic compound (for example, 1-methylnaphthalene) as a liquid at room temperature and having two benzene rings and at least one cyclic structure having no double bond , And coal extraction accelerators that do not contain nitrogen (for example, acenaphthene, fluorene, and dibenzofuran) are used to extract coal. |
