Abstract

Ultra-fine, nano-crystalline six-line ferrihydrite (5Fe2O3-9H2O) and cubic zirconia (ZrO2) powders have been produced using the Rapid Thermal Decomposition of precursors in Solution (RTDS) technology. Nano-crystalline RTDS six-line ferrihydrite powder used as anin situ precursor for first-stage direct coal liquefaction catalysts increased the liquefied products from Blind Canyon Seam coal by 22% absolute over thermal background at 350°C. Initial sintering studies performed on nano-crystalline RTDS ZrO2 powder have also been presented and compared to predictions made from theories derived for micro-crystalline powders.
