Promoted Fischer-Tropsch catalysts

Neutron Scattering Studies of Heterogeneous Catalysis

“…Several variants of the process operate around the world, with the catalysts predominantly based on Fe-and Co-containing materials. 231 Whereas recent large-scale unit operations have tended to feature Co catalysts, there is an increasing interest in Fe-based catalysts, not least as they offer the opportunity to cosynthesize olefins alongside alkanes, which otherwise tend to dominate the product slate. 231 Despite wide application, there remains considerable uncertainty about how FTS catalysts operate.…”

Schulz describes "the true F-T catalyst to be "constructed" under reaction conditions in processes of self-organization".…”

“…Fischer–Tropsch synthesis (FTS) is a well-established catalytic reaction system using synthesis gas (CO and H 2 ) obtained from resources such as coal, natural gas, and biomass to produce a variety of hydrocarbon products. Several variants of the process operate around the world, with the catalysts predominantly based on Fe- and Co-containing materials . Whereas recent large-scale unit operations have tended to feature Co catalysts, there is an increasing interest in Fe-based catalysts, not least as they offer the opportunity to cosynthesize olefins alongside alkanes, which otherwise tend to dominate the product slate …”
