Carbon-supported metal sulfides catalysts for coal liquefaction and upgrading of coal liquids Sakanishi, K. et al. DGMK Tagungsber., 1997, 9704, (Proceedings ICCS '97, Volume 3), 1421-1424. 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 highly dispersed supporting of active metal species on the surface and high dispersion of the particles in the coal liquid. The hydrogenation activity of various C-supported metal sulfides catalysts were also investigated to gain insight into the influences of metals and C species on the catalytic activity. Results are presented and the relationship between the catalytic activity and species of metals and carbon supports is discussed briefly.

## In Polish) Coal liquefaction research performed in the Central Mine Institute since 1967, with emphasis on a new concept introduced in 1980, is reported. This concept was a direct, one-step, autocatalytic hydrogenation of coal-oil paste at higher temperature and higher pressure. The paper discus
