The changes in the properties of iron-based catalysts during liquefaction using a bench scale unit (BSU) were investigated. It was found that S/Fe, atomic ratio of sulfur to iron in the catalyst system to be charged into a reactor, had great importance for surpression of catalyst deactivation. At the S/Fe of 1.2 a decrease of pyrrhotite content, an increase of troilite content and the crystal growth of iron sulfide were observed with the proceeding of reaction, but at the S/Fe of 3.0 both the formation of troilite and the crystal growth of pyrrhotite were remarkably surpressed.
