Abstract
The performance degradation and the recovery in the catalytic steam reforming reaction were examined by the test pieces, using ethanol-blended gasoline contained sulfur. It was found that the reason for the hydrogen generation being maintained though sulfur existed, when there is oxygen in the recovery, is that the oxygen removes the carbon from the catalyst. The oxygen concentration and temperature on the recovery operation have confirmed to become lower with improved catalyst carrier (CZA:Ceria-Zirconia-Alumina). Even if the hydrogen concentration fell because the hydrogen generation was degraded by the use of gasoline, that was recovery by the use of E85. The hydrogen generation was not degraded when the improved catalyst is used over a period of 70 hours.
