| Description |
The changes that occurred in tbe physico-chemical properties of a commercial
Co-Mo-A1203 catalyst on industrial usage were examined. The catalyst under study
had operated satisfactorily, meeting the full guarantees on its life, but had to
be discarded after six regenerations due to shortened cycle lengths. It was observed
that changes in the texture and structure of the support alumina and loss of
the active components (Mo03 and CoO) had occurred. Also, the spent catalyst was
found to be more acidic, resulting in faster coke pick up during reaction. Some
evidence for the weakening of the Mo03 - A1203 interaction was also noticed. The
reasons for the above changes in the physico-chemical properties, believed to be
responsible for the short cycle lengths of the catalyst, are analysed.
