Tar vapours have been hydrotreated in the second stage of a fixed-bed two-stage hydropyrolysis reactor using hydrous titanium oxide catalysts exchanged with Ni, Co, Mo and Pd and a commercially available Ni/Mo on alumina catalyst. The primary tar, which accounted for 25-30% daf coal (UK bituminous, 82% dmmf C) was converted at 400/sup 0/C and 150 bar to a colourless liquid low in heteroatoms of which up to 40% boiled below 150/sup 0/C. The gas yield was only slightly higher than that obtained in corresponding single-stage tests. A lower boiling product was obtained with Ni/Co/Mo hydrous titanium oxide than with the commercial Ni/Mo catalyst.
