26.石炭前処理による液化反応の促進と触媒回収への効果

抄録

Coal pretreatments were investigated in order to accelerate the depolymerization of coal macromolecules and to facilitate the catalyst recovery. Wyoming coal was activated by the mild preptreatment with 10% CH_3COOH aq. at room temperature for 24hr, the oil yield increasing to 45% with the decreased yields of the heavier products. The mild pretreatment also facilitated the recovery of a ferromagnetic Fe_3Al catalyst, decreasing the deposit amount on the catalyst.
