Abstract
A process for preparing shaped catalyst bodies whose active composition is a multielement oxide, in which a finely divided precursor mixture with addition of graphite having a specific particle size is shaped to the desired geometry and then treated thermally.
Claims29
A process for preparing shaped catalyst bodies whose active composition is a multielement oxide, in which a finely divided precursor mixture which comprises added graphite as a finely divided shaping assistant is shaped to the desired geometry and the resulting shaped catalyst precursor bodies are treated thermally at elevated temperature to obtain the shaped catalyst bodies whose active composition is a multielement oxide, wherein
- a) for the specific surface area OG of the finely divided graphite:
- 0.5 m2/g≧OG≦5 m2/g
- and
- b) for the particle diameter d50 of the finely divided graphite:
- 40 μm≦d50≦200 μm.
