Fe₃O₄ Nanoparticles Supported on Modified Coal toward Catalytic Hydrogenation of Coal to Oil.

ABSTRACT: Iron-supported catalysts exhibit good catalytic performance in direct coal liquefaction (DCL), but the effect of the carrier on the performance of the composite catalyst is unclear. In this paper, a simple solid-state synthesis strategy for the preparation of coal-loaded Fe₃O₄ nanoparticles (Fe₃O₄/Coal) and the hydrochloric acid treatment of coal-loaded Fe₃O₄ nanoparticles (Fe₃O₄/Coal-HCl) is presented. The resulting composite was used as a catalyst for DCL. The effects of supports on the structure and performance of iron-supported catalysts have been illustrated. After the acid pretreatment of the catalyst carrier coal, the surface structure and functional groups changed, which affected the aggregation
