MIXED VANADIUM-MOLYBDENUM OXIDES AS CATALYSTS FOR PARTIAL OXIDATION OF CROTONALDEHYDE

摘要

The vanadium-molybdenum mixed oxide based catalysts were prepared differing in the ratio of vanadium to molybdenum contents.Catalysts were characterised by the XRD,FTIR,N,-BET and XPS methods.The catalytic activity and selectivity to maleic anhydride and furan in the partial oxidation of crotonaldehyde were measured in the temperature of range 260-360°C.The results from the catalytic activity measurements were related to the occurrence of vanadium-molybdenum oxide compounds.
