Catalytic activities of various iron ores were investigated to develop a high activity catalyst in a direct coal liquefaction. Following results were obtained.<BR>(1) Laterite ores were found to have a high activity in catalysis for the coal liquefaction.<BR>(2) The liquefaction with various iron catalysts suggested that the ratio of Al<SUB>2</SUB>O<SUB>3</SUB>/Fe<SUB>2</SUB>O<SUB>3</SUB>, transition metals (Ni, Co, Cr) and surface area of the ore played an importantrole.<BR>(3) In the absence of elementary sulfur, the liquefaction afforded low sulfur products along with high yield.<BR>(4) Comparision of the are with red mud in the hydrocracking of 1-methylnaphthalene showed that the are had higher activities in hydrogenation of aromatic rings and in hydrocracking of alkylaromatics.
