Fig. 11. CO2 reforming of CH4 over rhodium catalysts. (A, top left) CO2 conversion for 1 wt.% Rh/Na-Y and 1 wt.% Rh/Al2 O3 at 1 atm (AP) and 27 atm (HP) at
750 8C. (Rh chloride was used for IWI); (B, top right) Effect of Rh loading on CO2 and CH4 conversion over Rh/Na-Y (IWI) and Rh/Al2O3 (IWI) catalysts in at 27 atm
and 750 8C (TOS: 90 min); (C, bottom left) CO and H2 yields for 1 wt.% Rh/Na-Yand 1 wt.% Rh/Al2 O3 at 1 atm (AP) and 27 atm (HP) at 750 8C. (Rh chloride was
used for IWI) (TOS: 90 min); (D, bottom right) Temperature programmed oxidation profiles from TGA of used 1 wt.% Rh/Na-Y (IWI) and 1 wt.% Rh/Al2O3 (IWI)
used catalysts after CO2 reforming of CH4 at 1 atm and 27 atm and 750 8C (after TOS of 300 min).
