40.極性溶剤蒸気で膨潤処理した石炭の迅速熱分解による低温架橋形成反応の抑制

抄録

Flash pyrolysis of the coal swollen by polar solvent vapors was proposed for controlling the primary reaction. The polar solvent molecules combined strongly with the non-covalent bonding sites in coal suppressed the cross-linking formation reaction during the pyrolysis at temperatures as low as 400 to 500℃, which increased the conversion and the tar yield by 56% and 28%, respectively, for a brown coal.
