Iron -based catalysts have been widely studied and applied in direct coal liquefaction, due to their rich sources, relatively low cost and better activity. This article provides an overview of the research progress of iron-based catalysts including natural iron minerals and industrial wastes, synthetic ultrafine iron catalyst, water -soluble and oil -soluble iron catalyst, the modified iron catalyst in direct coal liquefaction. The catalytic mechanism of iron -based catalysts is discussed and some suggestions about the research prospect for iron-based catalysts with industrial application potential is presented.
