Sintering of supported cobalt nanoparticles is one of the main deactivation mechanisms in the Fischer–Tropsch synthesis. In this study, crystallite growth was studied with an alumina-supported catalyst in real time and as a function of process cond

The oxidation of nanosized metallic cobalt to cobalt oxide during Fischer–Tropsch synthesis has long been postulated as a major deactivation mechanism apparently related to cobalt crystallite size. To establish a connection between cobalt crystalli

The application of Mossbauer emission spectroscopy to study cobalt based Fischer–Tropsch catalysts for the gas-to-liquids process was investigated. It was shown that Mossbauer emission spectroscopy could be used to study the oxidation of cobalt as

International audience; Cobalt catalysts as used in the Fischer-Tropsch synthesis (FTS) are relatively expensive (as compared to iron) and need to have a high metal dispersion and long life to be able to offer a good balance between cost and performa

The oxidation of cobalt during Fischer–Tropsch synthesis (FTS) has long been postulated as a major deactivation mechanism. In this study, wax coated samples of a Co/Pt/Al2O3 catalyst were taken from a 100-barrel/day slurry bubble column reactor ope
