Abstract
Fractions of a coal-derived liquid were prepared by preparative liquid chromatography and used as feeds to a high-pressure flow reactor, where they underwent hydroprocessing reactions catalysed by sulphided Ni Mo/ γ Al 2 O 3 . The feeds and products were characterized by capillary-column gas chromatography with a flame ionization detector and a Hall electrical conductivity detector, the latter being sulphur- or nitrogen-specific. The results were used to determine quantitative kinetics of the hydroprocessing reactions of individual compounds in the coal-derived liquids under the conditions of potential industrial processes.
