Effect of pre-treatment on physico-chemical properties and stability of carbon nanotubes supported iron Fischer–Tropsch catalysts

The characterization of micro-structure of cobalt on γ-Al2O3 for FTS: Effects of pretreatment on Ru–Co/γ-Al2O3

“…The degree of reduction (DOR) was calculated using Eq. (3), which is defined as the ratio of hydrogen consumed for the complete reduction of metal oxides from ambient temperature to 900°C to the amount of hydrogen calculated for this complete reduction [24].…”

Pore size effects in high-temperature Fischer–Tropsch synthesis over supported iron catalysts

“…Indeed, our results show that silica pore sizes affect both iron dispersion, ease of carbidization and catalytic performance. The literature presents numerous publications [6,7,40,52,[76][77][78][79][80][81] which relate iron particle size to the reaction rate and hydrocarbon selectivity in high-temperature FT synthesis. Most of reports have addressed however either bulk iron catalysts or iron catalysts containing different promoters (K, Mn, S, etc.).…”

Fischer-Tropsch synthesis nanostructured catalysts: understanding structural characteristics and catalytic reaction

“…A striking enhancement of the catalytic activity of Rh-Mn particles confined inside CNTs for the conversion of syngas to C 2 oxygenates was also reported [136]. As the functional groups on carbon surface were demonstrated to be able to affect the FTS performance of the iron catalysts, Dalai et al studied acid treatment effect in iron/CNT catalyst [137]. They found that HNO 3 treatment increased the surface area as well as the number of defects.…”
