Development of binder pitches from coal extract and coal-tar pitch blends

Pyrolysis of coal tar pitch binders

✍ R.W. Wallouch; H.N. Murty; E.A. Heintz 📂 Article 📅 1972 🏛 Elsevier Science 🌐 English ⚖ 624 KB

Thermogravimetric analysis techniques have been adapted to study the thermal decomposition of six coal tar pitches. Two material constants are introduced to describe the thermal stability and/or reactivity of coal tar pitches. These constants can be correlated with the softening point of the pitches

The transverse structure of pitch fiber has been successfully controlled by changing the pitch flow conditions at the upper portion of the capillary in spinning. The mean size of mesophase domains in the transverse section of pitch rod extruded from the capillary was found to decrease monotonously w

Shpol'skii luminescence spectroscopy of extracts of coal and coal-tar pitch

✍ John A.G. Drake; Derry W. Jones; Brian S. Causey; Gordon F. Kirkbright 📂 Article 📅 1978 🏛 Elsevier Science 🌐 English ⚖ 382 KB

Shpol'skii luminescence spectra in straight-chain-alkane matrices at 77 K have been measured from carbon-disulphide extracts of nine coal macerals and a cyclohexane extract of a coal-tar pitch. Twelve individual polycyclic hydrocarbons, containing from three up to ten rings, have been identified. Th
