The catalytic activity of Rh/CeO2/SiO2 was assessed for the partial oxidation of tar derived from spent malt. This catalyst was developed for the gasification of cedar wood at lower temperatures than conventional methods, such as steam reforming using Ni catalyst and or without catalyst. Partial oxidation of spent malt in the absence of catalyst yielded tar with a carbon based yield almost the same as that from cedar wood. Partial oxidation of the tar from cedar wood pyrolysis over Rh/CeO2/SiO2 and Ni catalyst converted the tar almost completely. On the other hand, tar from the pyrolysis of spent malt had lower reactivity than that of cedar wood. Higher temperatures such as 923 K were needed for tar conversion to the similar level to tar from cedar wood even over Rh/CeO2/SiO2. The nitrogen content in spent malt was much higher than that in cedar wood. The effect of NH3 addition on the partial oxidation of cedar wood was investigated. Furthermore, tar derived from cedar wood and spent malt was analyzed by GC-MS. Various nitrogen-containing hydrocarbons were observed in the tar derived from spent malt, although oxygenates were observed in the tar from cedar. Nitrogen-containing tar is only removed with difficulty.
