36.官能基修飾-溶剤膨潤を利用した新しい熱分解反応設計の試み

抄録

A new pyrolysis method utilizing oxidation and solvent swelling was presented for increasing the liquid yield. Coal oxidized by several acids at low temperatures to create non-covalent bonding sites, then it was swollen by tetralin or wax. The modified and swollen coal was pyrolyzed using a Curie-point pyrolyzer at 764℃, which realized significant increases in the total volatiles and the tar yield. The increases were found to be realized through the suppression of crosslinking reactions. Thus it was clarified that the coal could be modified to more flexible materials through oxidation and solvent swelling. This presents a possibility to design the coal pyrolysis reaction.
