In order to investigate the behaviour of coal liquefaction reaction in early stage before reactors, a coal slurry sample was withdrawn from outlet of the preheater of NEDOL Process 1 t/d Process Supporting Unit (PSU). The main product was still solid residue, while yields of oil, CO + CO* and H20 were low.

Aslphaltenes are difficult to characterize by any procedure that involves chromatography. In an attempt to obtain useful information on unfractionated asphaltenes and their structural relations to their parent coals, asphaltenes from a set of eight coals of hvA rank and different coalification histo
NiMo sulfide catalysts were supported well with ultrafine hollow particles of a particular carbon black (Ketjen Black: KB). This catalyst exhibited an excellent activity for coal liquefaction and can be recovered from the liquefaction residue for recycling. The high activity is ascribed to the highl
