Characterization of tars and pitches from coal pyrolysis
Fuel Processing Technology, 1988 Abstract Application of the following methods for the characterization of tars and pitches from coal pyrolysis is discussed: gas chromatography, high-performance liquid chromatography, supercritical fluid-chromatography, UV/VIS absorption spectrometry, fluorescence and phosphorescence spectrometry, and extrography.

Fuel Processing Technology, 1987 Abstract The effect of chloroform extraction on pyrolysis product distributions from three hard coals and a lignite were found to differ markedly between slow and fast pyrolysis. The decline in flash pyrolysis tar yields upon extraction is considerably larger than the amount of extract removed whereas in slow pyrolysis the sum of tar plus extract ...
