โœฆ Synopsis


The single greatest influence on the mesophase microstructure is the chemical composition of the organic precursor. The effects of oxygen content and structural parameters of precursors from solvent fractions of coal liquefaction products on the microstructure and pyrolysis yields were determined. The fractions were analysed using the Brown-Ladner method to obtain average molecular structural parameters. It was found that pyrolysis vield increases with increased aromaticitv and oxygen content and that mesophase microstructure is determined primarily by the oxygen content of the precursors.--

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

Abstr anthracene chars heat treated between 500 and 1200ยฐC is developped and applied to d.c. electrical conductivity, paramagnetic susceptibility and apparent density. An inhomogeneous process for the carbonization is proposed, in agreement with recent results on the structure of these chars. acts 3
