Fischer Tropsch synthesis using cobalt based carbon catalysts

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...

Tropsch synthesis using Co based carbon catalysts

Deactivation Behavior of Carbon Nanotubes Supported Cobalt Catalysts in Fischer-Tropsch Synthesis

The effects of electronic properties of inner and outer surfaces of Carbon Nano Tubes (CNTs) on the deactivation of cobalt Fischer-Tropsch (FT) catalysts were studied. The comparative characterization of the fresh and used catalysts by TEM, XRD, TPR, BET and H2 chemisorption showed that cobalt re-oxidation, cobalt-support interactions and sintering are the main sources o...

A 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...

Design, 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...
