Abstract
Low-temperature coal pyrolysis liquids produced in the presence or absence of additives (calcium oxide and Genstar, a dolomitic material) were separated by adsorption chromatography. Selected fractions were analyzed using infrared and carbon-13 nuclear magnetic resonance and gas chromatography/mass spectroscopy to determine the thermal reactions of aromatic compounds with these additives. The separation and spectroscopic results showed that the lower and higher phenols were deoxygenated. In addition, calcium oxide induced a variety of reactions including the cracking of alkanes and alkanes and the aromatization of alkanes.
