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 کاملA review of Fischer-Tropsch synthesis on the cobalt based catalysts
Fischer-Tropsch synthesis is a promising route for production of light olefins via CO hydrogenation over transition metals. Co is one of the most active metals for Fischer-Tropsch synthesis. Some different variables such as preparation parameters and operational factors can strongly affect the selectivity of Fischer-Tropsch synthesis toward the special products. In the case of preparat...
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...
متن کاملPromoted Iron-Based Catalysts for the Fischer–Tropsch Synthesis:Design, Synthesis, Site Densities, and Catalytic Properties
Iron-based catalysts were prepared by using promoters (K, Ru, Cu) and synthesis and activation protocols that inhibit sintering of oxide precursors and favor the nucleation of small Fe carbide crystallites. The effects of promoters on reduction/carburization behavior, on Fischer–Tropsch synthesis (FTS) rates, and on the number of CO binding sites formed during reaction were examined by combinin...
متن کامل281. Promoted Hydrotalcite Based Cobalt Catalyst for Fischer Tropsch Synthesis Application
The effects of using different promoters on hydrotalcite based cobalt (HT-Co) catalyst for FischerTropsch Synthesis was studied in this paper. The HT-Co catalysts were synthesized by using hydrothermal method whereas zinc and zirconium were added separately as promoters, by wetness impregnation method. The main aim of the study is to see the difference in properties of both zinc and zirconium p...
