METHOD FOR CONTINUOUSLY MANUFACTURING GEOMETRIC CATALYST MOLDED BODIES K

摘要

The invention relates to a method for manufacturing geometric catalyst molded bodies K, the active mass of which is a multi-element oxide, which contains the element Mo, the elements Bi and/or V, and one or more of the elements Co, Ni, Fe, Cu, and alkali metals, wherein a fine-particle mixture is produced using sources of the various elements, said fine-particle mixture is coarsened into a powder by compression agglomeration, molded bodies V are formed from the coarsened powder by compression agglomeration, said molded bodies are separated into undamaged molded bodies V+ and damaged molded bodies V-, the undamaged molded bodies V+ are transformed into the catalyst molded bodies K by thermal treatment, and the damaged molded bodies V- are ground and fed back into the production of the fine-particle mixture.
