Plate-type metal monolithic anodic alumina supported Ru catalysts prepared by impregnation method has been employed for the kerosene steam reforming. The characteristics of the catalysts were analyzed by ICP, BET, TG and FESEM. We found that although plate-type Ru/Al2O3 catalyst displayed favorable activity in the long-term stability test, coke deposition resistance should be further improved. In order to inhibit the coking during the reforming reaction, ceria was added to Al2O3 support to synthesize Ru/Ceria-Al2O3 catalysts. The results showed that ceria addition to the Ru/Al2O3 catalyst enhanced the catalyst stability, resulting from the lower content of coke formation on the catalyst surface. Furthermore, it showed that the content of ceria had a greater impact on the content of coke formation on the catalyst surface. If more ceria were contained in Ru/Ceria-Al2O3 catalyst, less coke would be formed over the catalyst surface during the reaction.
