Kinetics and mechanism of catalytic hydroprocessing of components of coal-derived liquids. Seventeenth quarterly report, May 16, 1983-August 15, 1983
The objective was to establish the reaction network for the catalytic hydroconversion of a simple compound representative of the organic-oxygen compounds in coal liquids, namely 1-naphthol. The catalyst was a typical commercial, sulfided NiO-MoO/sub 3//..gamma..-Al/sub 2/O/sub 3/, and experiments were carried out with liquid-phase reactants in a stirred batch reactor under conditions approaching those of practical practice. The results summarized by the network of Figure 3 demonstrate that aromatic ring hydrogenation and direct oxygen extrusion (HDO) occur in parallel, as in the dibenzofuran/H/sub 2/ network. The pattern is akin to that observed in catalytic hydroprocessing of organosulfur compounds such as dibenzothiophene and benzo(b)naphtho-(2,3-d)thiophene. The pattern is different from that observed in catalytic hydroprocessing of organonitrogen compounds such as quinoline - in which extensive aromatic ring hydrogenation procedes C-N bond breaking.
