Abstract:
Monometallic (Ni-, Co-, Cu-, and Fe-containing, Me25/Al2O3) and bimetallic (NixCo(50-x)/Al2O3) catalysts were synthesized via precipitation in supercritical carbon dioxide. The catalytic activity of these systems was evaluated in the transfer hydrodechlorination of chlorobenzene, employing supercritical isopropanol as a hydrogen donor, at temperatures ranging from 250 ◦C to 275 ◦C. The hydrodechlorination rates for monometallic catalysts followed the order: Ni25/Al2O3 > Co25/Al2O3 > Cu25/Al2O3 > > Fe25/Al2O3. For bimetallic catalysts
(NixCo(50-x)/Al2O3), the hydrodechlorination rate increased with increasing nickel content. It was observed that significant coarsening of metal particle crystallites occurred during hydrodechlorination; however, this phenomenon did not demonstrably affect catalyst activity
