Research Progresses in Fischer-Tropsch Synthesis Process

The recent developments in the research of catalysts,mass transfer and heat transfer for low- and high-temperature Fischer-Tropsch synthesis were reviewed.Three processes,namely fixed bed,fluidized bed and slurry bed,used in the synthesis were compared based on the catalysts,heat transfer,mass transfer,product distribution and reaction conditions.Some novel Fischer-Tropsch synthesis processes,namely microstructured reactor,monolith reactor and supercritical fluid were introduced.The reactor structure,catalyst design and micro reactor will be hot points for the research of Fischer-Tropsch synthesis in future.
