QI-free coal tar pitch is separated into a toluene-soluble (TS) and a toluene-insoluble (TI) fraction by solvent extraction. The effect of controlled mixing of both fractions on mesophase formation is studied. The formation of mesophase is correlated with the carbon and hydrogen contents of the samp

The pyrolysis of coal tar and petroleum pitches was studied under nitrogen pressures from 2 to 150 bar at temperatures between 300 and 600°C. The resulting residues were investigated by TGA, polarized-light microscopy and X-ray diffraction. It is shown that increasing pressure does not only increase
