✦ Synopsis

In Japanese) 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to investigate the behaviour of coal liquefaction reaction in early stage before reactors, a coal slurry sample was withdrawn from outlet of the preheater of NEDOL Process 1 t/d Process Supporting Unit (PSU).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. 98100209 Coal liquefaction tests conducted in the Central Mine Institute Rusin, E. et al. Karbo-Energochemical-Ekol., 1996, 41, (7). 244-246. (In Polish) Research concerning coal liquefaction performed since 1967 at the Central Mine Institute is discussed. Particular attention is given to a new concept introduced in 1980: a direct, one-step, autocatalytic hydrogenation of coaloil paste at higher temperature and higher pressure. A 200 ton coal/day hydrogenation plant is discussed. 98100210 Coliquefaction of coal, tar sand bitumen and plastic interaction among coal, bitumen and plastic
