This study involved cobalt catalysts tested in a slurry bubble FTS reactor operating at realistic conditions, over extended periods. The spent catalyst samples were characterized for aluminate formation by a range of techniques. We found that cobalt aluminate formation during FTS at realistic conditions is not a major deactivation mechanism.
