Abstract:
A number of mixed oxide Ce0.75Zr0.25O2 supports were prepared, tested for reproducibility, and characterized by physicochemical methods. The most reproducible preparation method was adapted for depositing the mixed oxide on a FeCrAlloy mesh substrate coated by a protective alumina layer. Based on the obtained structured Ce0.75Zr0.25O2/θ-Al2O3/FeCrAl support, the Rh/Ce0.75Zr0.25O2/Al2O3/FeCrAl and Pt/Ce0.75Zr0.25O2/Al2O3/FeCrAl catalysts were prepared and tested in the reactions of partial oxidation of LPG and deep oxidation of anode gases, respectively. Rh/Ce0.75Zr0.25O2/Al2O3/FeCrAl provided complete conversion of LPG into synthesis gas of a composition close to the equilibrium one. Pt/Ce0.75Zr0.25O2/Al2O3/FeCrAl provided complete conversion of all components of the anode gases at GHSV = 20,000–40,000 h−1; however, at higher GHSV values, methane conversion decreased. The studies on the effect of methane content on deep oxidation of anode off gases showed that methane conversion began to decrease at a 1.5-fold excess of methane and dropped to 50% at a 10-fold excess of methane.
