39.流通反応器による各種石炭の高温溶剤中での抽出・熱分解挙動の検討(石炭利用における科学と工学の接点)

抄録

Several coals were extracted in a flowing solvent to examine the solubilization/deporimarization behavior of coal in liquid phase under 10MPa at 200 to 350℃. The flowing solvent was used to minimize the secondary reaction between the extract and macromolecular networks of coal. The extract was further separated into precipitated solid (deposit) and soluble fraction (solution) at room temperature. Bituminous coals colud be extracted by 65 to 80% at 350℃ in either tetralin or 1-methylnaphthalene. The proposed extraction method will contribute to clarify coal structure. It also has possibilities of new coal conversion process.
