抄録

The reflux pretreatment of oxidized hydropyrene was examined in order to increase its coke yield. The pretreatment between 350 and 380 degree C was effective to increase the yield by 8%. The chemical constituents in the pitches derived from hydropyrene were analysed by means of the solvent fractionation, gas chromatography and mass spectroscopy to reveal the chemical change during the pretreatment. The increase of the coke yield is ascribed to the dehydrogenative condensation of trimers and tetramers of pyrene units.
