✦ Synopsis

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to investigate the behaviour of coal liquefaction reaction in early stage before reactors, a coal slurry sample was withdrawn from outlet of the preheater of NEDOL Process 1 t/d Process Supporting Unit (PSU).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.
