Abstract

The asphaltene fraction from a hydrogen-donor solvent extract of bituminous coal has been isolated and submitted to catalytic hydrogenation over the temperature range 200-425 degree C. The products of these hydropyrolysis reactions have been fractionated into n-pentane-solubles, benzene-solubles, pyridine-solubles and pyridine-insolubles. Yields of each fraction have been contrasted with yields from simple pyrolyses under nitrogen gas, in an effort to improve our understanding of the fragmentations involved. The role of asphaltenes in coal liquefaction processes is sufficiently crucial to justify its investigation in isolation from other coal solubility classes.
