Fe(CO)5/Sulfur-Catalyzed Liquefaction of Yallourn Coal in Syngas-Water Systems

Pentacarbonyliron with sulfur was found to be an excellent catalyst precursor for liquefaction of Yallourn coal using syngas-water as a hydrogen source. Both the high coal conversion and well-balanced consumption of syngas were achieved by controlling the amount of water. The two-staged reaction at 375 °C for 1 h and then at 425 °C for 1 h showed high coal conversion of 96.7% with high oil yield.
