PROCESS FOR PODUCTION OF COMPOSITE OXIDE CATALYSTS |
摘要 |
In the production of a Mo-Bi-Na composite oxide catalyst by the process comprising incorporating compounds as respective element sources into a composite and subjecting the composite to heating treatment in an aqueous system, bismuth oxide and/or bismuth subcarbonate are/is used as a Bi source compound and at least a part of the heat treatment is conducted at a temperature of 450 to 600 DEG C. The activity of the catalyst is significantly improved by introducing Bi in the form of the specified water insoluble compound into the catalyst. |
