The added labeled alcohols are mostly found in the product gas and water phase (≥99%) without being involved in any reaction over both fcc and hcp metallic cobalt. The data indicate that C-O bond of ethanol and 1-propanol remains mostly stable on cobalt under FTS conditions. However, 1-propanol is likely to be involved in a chain initiation after decarbonylation apart from being degraded into methanol on ruthenium.
