Which consequence results when a zeolite catalyst's pore structure degrades during Fischer-Tropsch synthesis?

💡 Explanation

When the pore structure degrades, diffusion limitations increase, hindering long-chain hydrocarbon formation because steric hindrance prevents longer molecules within the catalyst, therefore chain growth stops rather than methane formation occurring.
