Further insights into the effect of sulfur on the activity and selectivity of cobalt-based Fischer-Tropsch catalysts

- A sulfur poisoning study was performed on alumina-supported cobalt catalysts.
- A deactivation model has been proposed to describe sulfur poisoning.
- Sulfur decreases the selectivity to long chain hydrocarbons.
- Sulfur increases olefin hydrogenation.
- Sulfur has no significant effect on the selectivity to CO2.
