Implication

Experimental analysis demonstrates 98% activity recovery after oxidative regeneration of zeolite-containing cobalt catalysts, highlighting practical methods to counter long-term deactivation.

Key Points

To evaluate the mechanisms of deactivation and test regeneration strategies for zeolite-containing cobalt catalysts during prolonged Fischer–Tropsch synthesis in industrial-scale reactor tubes.
Conducted long-term operational testing of zeolite-containing cobalt catalysts over 3,000 hours on stream in reactor tubes sized comparably to industrial units.
Analyzed structural causes of catalyst deactivation and evaluated one mitigation method alongside two distinct catalyst regeneration approaches, including oxidative treatment.
Catalyst activity declined by 13% over 3,000 hours on stream, primarily driven by cobalt cluster agglomeration and surface carbon deposition.
Oxidative regeneration treatment successfully restored 98% of the catalyst's initial catalytic activity.
