Fischer Tropsch Synthesis: A Comparison of Iron and Cobalt Catalysts
Following WW II, it appeared that there would be a severe shortage of crude oil so that U.S. organizations initiated work on Fischer-Tropsch synthesis (FTS). Over a ten year period, the U.S. Bureau of Mines was budgeted $85 million for work on direct and indirect coal liquefaction. These funds would represent more than a billion dollars in today’s marketplace. A large (75 bbl/day) FTS pilot pla...
متن کاملTechnology Development for Iron and Cobalt Fischer-Tropsch Catalysts
A cobalt catalyst (25%Co/γ-Al2O3, prepared by slurry phase impregnation) was used in a fixed bed reactor under a pressure/density tuned supercritical fluid mixture of n-pentane/nhexane. By using an inert gas as a balancing gas to maintain a constant pressure, the density of the supercritical fluid could be tuned near the supercritical point while maintaining constant space velocity within the r...
متن کاملSurface Science Studies on Cobalt Fischer–Tropsch Catalysts
Fischer–Tropsch (FT) synthesis is a process in which synthesis gas (CO/H2) is catalytically converted into hydrocarbons and oxygenates via surface polymerizations. With this process, clean liquid fuels can be made from abundant natural gas reserves and renewable biomass sources, after first being converted to synthesis gas. In the last several decades, FT synthesis has attracted renewed attenti...
متن کاملDesign, synthesis, and use of cobalt-based Fischer-Tropsch synthesis catalysts
Catalyst productivity and selectivity to C5+ hydrocarbons are critical design criteria in the choice of Fischer-Tropsch synthesis (FTS) catalysts and reactors. Cobalt-based catalysts appear to provide the best compromise between performance and cost for the synthesis of hydrocarbons from CO/H2 mixtures. Optimum catalysts with high cobalt concentration and site density can be prepared by control...
