Experimental studies have been carried out to investigate some problems in the development and practical use of a catalytic combustor using a methanol mixture. For the suppression of undesirable exhaust emission, the possibility of using a catalyst with a higher amount of noble metal than the usual level as a component of the entire catalyst layer is examined. The combustion characteristics of the catalytic combustor with water-containing methanol and with aged catalysts are also investigated. From the results, it was found that undesirable exhaust emission during the startup period was suppressed by use of the higher noble metal loaded catalyst as a component of the catalysts. Formaldehyde emission was increased as the contained water was increased in the range of zero to 15wt%. The reaction region moved downward with the use of the aged catalyst, and the catalyst temperature profile was decreased. This indicates that the emission characteristic on unburned species is degraded.
