    The decomposition of methanol into CO and H2 on supported Pd based catalyst was investigated for recovery of unused heat at around 473 K. The decomposition of methanol into CO and H2 proceeded at lower temperature with greater endothermic heat compared with the methanol steam reforming reaction. The addition of Au or Pt was effective for increasing catalytic activity around 473-523 K. In particular, Pd with 30 wt.% Au added was the most active for methanol decomposition into CO and H2, and H2 yield on Pd-Au (7:3)/Al2O3 was 51% at 523 K. Although high H2 yield was achieved, yield of dimethyl ether (DME) was also high on this catalyst, especially at low temperature around 523 K. Formation of DME was significantly suppressed by using BaZrO3 for the support and also mixing BaZrO3 with Al2O3 for support of Pd-Au bimetal catalyst. Thus, theuse of BaZrO3 for the support was effective for increasing CO selectivity and Pd-Au (9:1)/BaZrO3-Al2O3 (1:1) was highly active for methanol decomposition into CO and H2, and negligible amount of DME was formed around 523 K.
