Аннотация

A number of mixed oxide Ce_0.75Zr_0.25O₂ 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 Ce_0.75Zr_0.25O₂/θ-Al₂O₃/FeCrAl support, the Rh/Ce_0.75Zr_0.25O₂/Al₂O₃/FeCrAl and Pt/Ce_0.75Zr_0.25O₂/Al₂O₃/FeCrAl catalysts were prepared and tested in the reactions of partial oxidation of LPG and deep oxidation of anode gases, respectively. Rh/Ce_0.75Zr_0.25O₂/Al₂O₃/FeCrAl provided complete conversion of LPG into synthesis gas of a composition close to the equilibrium one. Pt/Ce_0.75Zr_0.25O₂/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.
