MASS TRANSFER LIMITATIONS ON FIXED-BED REACTOR FOR FISCHER-TROPSCH SYNTHESIS
IntroductionIndirect conversion of coal, heavy oil, natural gas, and biomass into liquid fuels (e.g., gasoline, diesel, wax) can play a major role in solving the energy problem (i.e., the high oil price ～130 US$/bbl). Furthermore, since the synthetic liquid fuels are ultra-clean (no aromatics, no sulfur, and no nitrogen compounds), it can easily satisfy the upcoming stricter environmental regulations both in Europe and the U.S.A.Fischer-Tropsch synthesis is the key technology of converting synthesis gas (H2/CO=2) into the liquid fuels in the indirect conversion. The most important issues in Fischer-Tropsch synthesis are the selection of catalyst and reactor. In the case of the catalyst, considering the catalyst deactivation rate, there is a shift from an iron (Fe) catalyst to a cobalt (Co) catalyst. Cobalt is a highly active catalyst according to its cost and availability. Also, since the Fischer Tropsch synthesis is highly exothermic, various types of reactor (fixed-bed, fluidized-bed, ebulliating-bed, and slurry-phase) are considered to efficiently control the exothermic reaction heat.
