Abstract

A novel flow-through hydrothermal process, termed the Rapid Thermal Decomposition of precursors in Solution (RTDS), has been used to generate large quantities of ultra-fine, nano-crystalline hematite (α-Fe₂O³), 6-line ferrihydrite (5Fe₂O₃.9H₂O) and ferric oxyhydroxysulfate powders. The heterogeneous catalytic activity of these powders towards C-C bond scission in the model compound naphthyl bibenzylmethane and in the first-stage liquefaction of Blind Canyon seam coal was investigated. The effects of the crystalline phase and the agglomerate size of these powders on their catalytic activity are reported.
