Summary:Methane/carbon dioxide mixed gas flow rates of 50-400 ml/min were applied at 1223 K in an infrared furnace to research methane dry reforming with CO sub(2), using iron oxide powder in molten salt. The utility of this approach for chemical storage of solar energy was weighed. The mixed gases passed through the FeO powder-containing molten salt and were decomposed into carbon monoxide, hydrogen, and water. Reducing the flow rate from 200 to 50 ml/min reduced the water production, and the reaction approached theoretical dry reforming. The methane reforming reaction studied was judged useful for conversion of solar energy into chemical energy.
