Abstract
A process for preparing a propane oxidation catalyst, the process comprising pre-calcining a catalyst precursor in a precalcining zone in an oxygen-containing gas, then feeding an oxygen-free gas to a purging zone until the gas exiting the zone is substantially free of oxygen, and calcining the pre-calcined precursor to obtain the catalyst.
