Abstract
PURPOSE: To extend the range of coals to which the treatment with organic solvent is applicable as well as to solve problems on slurry heating, by throwing coals which have been increased their coking ratio by rapid heating, into a high boiling organic solvent to quench rapidly and to maintain the condition for an adequate period.
