A highly stable catalyst for hydrogen production by steam reforming of 2-propanol is searched by reaction tests at 773 K and 673 K. At 773 K, Rh/Al2O3 ,Ru/Al2O3 and Pd/Al2O3 result in the stable hydrogen production. Co/Al2O3, initially results in the highest hydrogen production, however, the production decreases gradually as the time on stream increases. Rh/Al2O3 exhibits the highest stability for the hydrogen production also at 673 K, and is practical for the steam reforming.
