In order to examine the feasibility of catalyst recovery from liquefaction residue, fundamental study on properties in residue was carried out by using XRD, SEM/XMA, XAFS and XPS techniques. Residues were obtained lt/d NEDOL PSU plant which uses Wandoan, Illinois Wyoming coals as feedstocks synthetic pyrite catalyst. Special attention has been paid interaction with mineral matter heavy organics coal. It found that converted pyrrhotite during covered organic materials can be removed treating CS2/N-methyl pyrolidinone solvent.
