✦ Synopsis

Methane dry reforming with CO using FeO powder in molten salt has been investigated at various 2 flow rates of CH / CO mixed gases (CH / CO 5 1) between 50 and 400 ml / min at 1223 K in an infrared 4 2 4 2 furnace. This work is carried out to determine the usefulness of this method for the chemical storage of solar energy. The CH / CO mixed gases passing through the molten salt (Na CO / K CO 5 1) containing the FeO 4 2 2 3 2 3 powder were catalytically decomposed into CO, H and H O. The product gas mole ratios, CO / H / H O, were 2 2 2 2

shown to be 3:1:1 for a high flow rate of 200 ml / min and to be CO / H 5 2:1 for a low flow rate of 50 2 ml / min. The results were explained in terms of the kinetics of the CH -reforming reaction and the 4 thermodynamics of the redox process of FeO powder mixed in the molten salt;
