Monometallic and bimetallic catalysts (Pt, Ni, and Pt‐Ni) with single support (Al2O3, TiO2) and composite support (CeO2/Al2O3, CeO2/TiO2) were prepared and tested for water‐gas shift reaction in a tubular quartz reactor. Syngas and steam with different steam‐to‐carbon ratios served as feedstock. The operating pressure was fixed while the reaction temperature was varied. The measured results indicated that the monometallic Ni/Al2O3 catalyst exhibits the lowest CO conversion and H2 yield as compared with other catalysts. About the same CO conversion can be obtained from Pt and Pt‐Ni catalysts with single or composite support. However, higher H2 yield can be achieved from the TiO2‐supported catalyst compared with those supported by Al2O3. The experimental data also indicated that good thermal stability can be reached for the Pt‐based catalysts studied.
