Název v původním jazyce

Ruthenium and Platinum Catalysts Supported on Ce, Zr, Pr-O Mixed Oxides Prepared by Soft Chemistry for Acetic Acid Wet Air Oxidation

Popis výsledku v původním jazyce

These catalysts were prepared by conventional impregnation (5 wt.%) from platinum and ruthenium precursor salts. A screening of catalysts in CWAO at 200 °C under 2 MPa of partial oxygen pressure was performed and reveals that the best platinum catalyst is supported on pure ceria displaying large surface area. The mineralization of acetic acid solution reached 90% after 3 h of reaction on PtCe catalyst. For ruthenium catalysts, the highest conversion after 3 h of reaction has been reached by the Ru/Zr-Ce-O system (M3h = 88%). Ce(CO3)OH species, evidenced by FT-IR and XRD, were formed during the CWAO reaction essentially on well dispersed platinum catalysts supported on mixed oxides.
