A symposium on iron-based catalysts for coal liquefaction was held at the 205th ACS National Meeting, and some of the papers have been published in Energy & Fuels. Reviews of the development of catalysts for coal liquefaction were also published in Journal of the Japan institute of Energy, and Ozaki reviewed the results of the studies of upgrading residual oils by means of thermal cracking and coking under reduced pressures, catalytic cracking over nickel ores and iron oxides, and hydrodesulfurization, as well as hydrodemetallization. We reported that catalysis of metallic iron and iron-sulfide catalysts were affected by the S/Fe ratio; the activity increased with pyrrhotite formation and the activity was accelerated by the presence of excess sulfur. Activity of pyrite FeS{sub 2} for phenanthrene hydrogenation and activity of natural ground pyrites for cow liquefaction decreased with storage under air. On the other hand, the NEDOL process for a coal liquefaction pilot plant of 150 t/d which is one of the national projects in Japan, will use pyrites as one of the catalysts for the first-stage because FeS{sub 2} has high activity and is low in price. In this paper, we describe in detail the role of iron catalysts in hydroconversion of aromatic hydrocarbons.
