Abstract
Catalytic activities of various iron ores were investigated to develop a high activity catalyst in a direct coal liquefaction. Following results were obtained.(1) Laterite ores were found to have a high activity in catalysis for the coal liquefaction.(2) The liquefaction with various iron catalysts suggested that the ratio of Al2O3/Fe2O3, transition metals (Ni, Co, Cr) and surface area of the ore played an importantrole.(3) In the absence of elementary sulfur, the liquefaction afforded low sulfur products along with high yield.(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.
