Abstract

Reflux pretreatment of oxidized hydropyrene (OHP) was examined in the order to increase coke yield. Pretreatment between 350 and 380 degree C was found to increase the yield by approx. 8%. The chemical constituents in the pitches derived from hydropyrene were analyzed by means of solvent fractionation, gas chromatography, and field desorption mass spectroscopy to reveal the chemical changes during pretreatment. The increase of the coke yield is ascribed to the dehydrogenative condensation of trimers and tetramers of pyrene units. Refs.
