9 ハイパーコール溶剤分別成分の炭化特性(ハイパーコール製造・利用)

抄録

Hyper-coal (HPC), which is produced by solvent extraction of coal, has advantages of extremely low ash content and high fluidity upon melting, but exhibits relatively poor carbonization yield and vigorous foaming during carbonization. In this study, HPCs prepared from bituminous coals were further treated by solvent fractionation, and the carbonization properties of the fractions were elucidated. It was demonstrated that eliminating 20-50wt% soluble components from HPC was appropriate to obtain dense carbon material from HPC.
