Roles of the support in the hydrotreatment of a solvent refined coal (SRC) were studied to find a catalyst which can upgrade selectively its heavier component, comparing a natural clay and a titania as the support for the nickel-molybdenum with alumina of a commercial one. Although all supports showed similar overall activities for the production of the hexane-soluble (HS) fraction in the first run, both trial catalysts exhibited clearly consecutive transformation profiles (benzene insoluble (BI) → benzene-soluble (BS) but hexane insoluble (HI) → HS), indicating the definite selectivity preferential for the heavier fraction. The trial catalyst showed better durability in the second run and less hydrogen consumption probably due to less gaseous hydrocarbons in the product. A comparable catalytic activity of the titania-supporting catalyst in spite of its very small surface area (20 m2/g) may suggest the favorable effect of the catalyst-support interaction on the catalytic performance.
