Cobalt Catalysts Supported on Alumina Nanofibers for Fischer-Tropsch Synthesis: Effects of Catalyst Preparation and Aspect Ratio of Fibers

The pore size of the Fischer-Tropsch synthesis cobalt catalyst influences hydrocarbon selectivity to a greater extent than carbon monoxide conversion. The mass transport limitation effect increases resulting in increased H₂/CO ratio in catalyst pores, thus, increase in hydrogen concentration on the catalyst surface leading to the hydrogenation of olefins.
