The role of carboxylic acid in cobalt Fischer-Tropsch synthesis catalyst deactivation

- Acid does not enhance Co/Pt/Al2O3 Fischer-Tropsch synthesis catalyst deactivation.
- Co/Pt/Al2O3 catalyst exposed to acetic acid results in atomic carbon formation.
- Acetic acid decomposes at low temperature on a Co metal surface.
- Oxygenates on spent Co/γ-Al2O3 catalyst are located on γ-Al2O3 support.
