- W2504567874 abstract "The chemistry of coal carbonization was studied in an attempt to better understand the changes that take place as metallurgical coal becomes plastic. Infrared spectroscopy was used to study the transformation from coal-mesophase-semicoke and to relate the changes to those observed in the electron microscope. Spectra of semicokes produced from three different coals at various heat-treatment temperatures show changes that can be related to the fluid properties of the coals. Evidence of mesophase in the fluid range of temperature can be obtained from changes in the region of the spectra assigned to aromatic hydrogen out-of-plane bending modes. Heat-treatment temperatures above the fluid range result in condensation of the mesophase as hydrogen is lost." @default.
