Effect of different reaction conditions on the deactivation of alumina-supported cobalt Fischer–Tropsch catalysts in a milli-fixed-bed reactor: experiments and modeling

This paper focuses on the deactivation of a cobalt-based alumina-supported Fischer–
Tropsch catalyst in a milli-fixed-bed reactor under different operating conditions. Different
catalyst deactivation behaviors were observed at different syngas H2/CO ratios and
temperatures. The deactivation follows a two-step profile, where the initial deactivation is
attributed to sintering, whereas the long-term deactivation is due to carbon deposition or
cobalt oxidation on the surface. An unsteady-state semimechanistic model has been …
