Cobalt Catalyzed Fischer-Tropsch Synthesis with O2-Containing Syngas

Mechanism of Cobalt-Catalyzed CO Hydrogenation: 2. Fischer–Tropsch Synthesis

Fischer-Tropsch (FT) synthesis is one of the most complex catalyzed chemical reactions in which the chain-growth mechanism that leads to formation of long-chain hydrocarbons is not well understood yet. The present work provides deeper insight into the relation between the kinetics of the FT reaction on a silica-supported cobalt catalyst and the composition of the surface adsorbed layer. Cofeedi...

Fischer-Tropsch synthesis using bio-syngas and CO2

While Fischer-Tropsch synthesis (FTS) using coal and natural gas in conventional reactors is an almost well-established technology, the production of liquid hydrocarbons from syngas obtained from biomass is in its preliminary stages of commercialization in countries like Germany. With concerns about global warming and ways of disposing of CO2 being searched for, CO2 hydrogenation using FTS to l...

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...

Fe-based Fischer Tropsch synthesis of biomass-derived syngas: Effect of synthesis method

Effect of Structural Promoters on Fe-Based Fischer–Tropsch Synthesis of Biomass Derived Syngas

Biomass gasification and subsequent conversion of this syngas to liquid hydrocarbons using Fischer– Tropsch (F–T) synthesis is a promising source of hydrocarbon fuels. However, biomass-derived syngas is different from syngas obtained from other sources such as steam reforming of methane. Specifically the H2/CO ratio is less than 1/1 and the CO2 concentrations are somewhat higher. Here, we repor...
