64.各種石炭から高温抽出により調製したクリーンコールの液相熱分解(石炭利用における科学と工学の融合)

We have clarified that sevral bituminous coals could be extracted by 65 to 80% at 350℃ in a flowing solvent and the extract was separated into precipitated solid (deposit) and soluble fraction (soluble) at room temperature. The extract was found to be almost ash free. In this paper we examined the possibility to convert the extract into oil in high yield. It was found that pyrolysis of the exract in liquid phase at 450℃ yields more than 50kg/100kg-coal of oil.
