Patent ID: 7560412

Claim:
A method for the preparation of an attrition-resistant, cobalt-alumina catalyst comprising the steps: a) preparing an alumina slurry by combining an alumina powder with a peptizing agent, wherein said peptizing agent is selected from the group consisting of an acidic aluminum salt, an acidic cobalt salt, a mineral acid, a carboxy acid, and combinations thereof; b) combining a cobalt source with said alumina slurry; c) allowing said cobalt and alumina slurry to gel; d) homogenizing said cobalt and alumina gel with a sufficient amount of water to form a homogenized slurry; and e) spray-drying said homogenized slurry to form attrition resistant cobalt-alumina catalyst particles, wherein said catalyst comprises about 5 wt % to about 60 wt % cobalt and about 40 wt % to about 95 wt % alumina.
