METHOD FOR THE PRODUCTION OF CATALYTICALLY ACTIVE MULTIELEMENT OXIDE MATERIALS CONTAINING AT LEAST ONE OF THE ELEMENTS NB AND W AS WELL AS ELEMENTS MO, V AND CU BY MEANS OF A THERMAL TREATMENT IN A LOW-OXYGEN ATMOSPHERE

摘要

Nb, at least one of the elements W, and Mo, V, a catalytically active element is an element that contains Cu The method of generating the oxide material is disclosed. According to the method, a homogeneous dry mixture containing ammonium ions is produced, this molecular oxygen is subjected to heat treatment at an elevated temperature in the lower atmosphere. The partial amount of ammonium ions contained in a dry homogeneous mixture is decomposed ammonia is released, the oxygen concentration in the heat treatment atmosphere is increased during the heat treatment.
