Abstract
Two plate-type anodic alumina supported Ru catalysts, Ru/Al and Ru/Ce?Al, has been employed to investigate activities in the kerosene steam reforming reaction. H2 pre-reduction during the kerosene steam reforming was found not an essential procedure, in terms of activity and stability. In addition, the Ru/Ce?Al catalyst was more stable than Ru/Al without pre-reduction in the accelerated life test. In the 20 times of DSS operation over Ru/Ce?Al, no remarkable decline in kerosene conversion was observed, indicating that Ru/Ce?Al was tolerable to multiple cycles under such severe conditions without obvious deterioration. Under an electric heating pattern, the performance of catalyst Ru/Ce?Al was investigated. It showed that 100% of kerosene conversion would be obtained in just 15 min over the Ru/Ce?Al catalyst when the kerosene was introduced into the reactor. It also presented excellent stability during test and DSS operation, which indicates more promising lifetime for the Ru/Ce?Al catalyst in the wall-type reformer.
