摘要

the invention relates to a method for processing a catalyst for oxidizing u0434u0435u0433u0438u0434u0440u043eu0433u0435u043du0438u0437u0430u0446u0438u0438 u0430u043bu043au0430u043du0430 and / or oxidation u0430u043bu043au0435u043du0430, where the catalyst is a cat u0430u043bu0438u0437u0430u0442u043eu0440 based on mixed metal oxide containing molybdenum, vanadium and niobium, the method includes bringing a catalyst into contact with the gas mixture containing the inert gas and oxygen (o2).with the amount of oxygen is from 10 to less than 10000 u043eu0431.u0447. million to the total gas mixture at elevated temperatures.
