Beschreibung
Zusammenfassung:	PURPOSE:To prevent the decrease in activity as compared to conventional catalysts by letting V2O5 and K salt be carried in the ceramic-made catalytic carrier containing the specific amount of BaO and composed primarily of SiO2, Al2O3, etc. thereby constituting the oxidation catalyst. CONSTITUTION:The oxidation catalyst carrier is made of the ceramics composed primarily of SiO2 and/or Al2O3 and contains BaO at 1-10 (preferably 1-4)%, and its composition is composed of SiO2; 60-80wt% (hereinafter the same), Al2O3; 15-35, Na2O;
