REMARKABLE ABILITY OF TETRAHYDROFLUORANTHRENE IN THE LIQUEFACTION OF A SUB-BITUMINOUS COAL AT UNUSUALLY HIGH TEMPERATURE UNDER A MODERATE PRESSURE

Article abstract of DOI:10.1246/cl.1984.1461

An Australian sub-vbituminous coal was effectively liquefied under high temperature short contact time conditions at about 30 kg/cm² using 1,2,3,3a-tetrahydrofluoroanthrene (4HFL) as the solvent.The yields of the oil and asphaltene, the target products, were as high as 54 and 16percent, respectively, for a reaction at 560 deg C with zero contact time. 4HFL was principally converted into fluoranthrene together with some undefined four ring aromatic compounds.The efficacy of the present liquefaction procedures is introduced.
