چکیده مقاله
Medium-temperature shift reaction (MTS, 280–340 °C) has received much attention
for use in fuel processors. In this study, bifunctional Pt-Ni/CeO2 catalysts
were prepared by different Pt (0.1–0.5 %) and Ni (5–20 %) loadings, and investigated
for MTS reaction. X-ray diffraction, N2 adsorption and temperatureprogrammed
reduction tests were used to characterize the prepared samples. The
results showed that Pt-Ni bimetallic catalysts have higher CO conversion in comparison
to Pt/CeO2 monometallic catalyst. Furthermore, the sequential synthesis
method of Pt and Ni impregnation was preferred to the simultaneous one, which
is due to the better Pt dispersion on catalytic surface. Steam to carbon ratio variations
study showed the maximum CO conversion to be in the range of 4.5.
