Ru-M (M = Fe or Co) Catalysts with high Ru surface concentration for Fischer-Tropsch synthesis

A simple continuous reaction for the synthesis of quinoline compounds

“…3, the reduction peaks of the Fe/γ-Al 2 O 3 catalyst near 330 °C and 550 °C are attributed to the reduction peaks of Fe 2 O 3 to Fe 3 O 4 and the reduction peaks of Fe 3 O 4 to Fe, respectively. 25 The Ru/γ-Al 2 O 3 catalysts show a reduction peak near 125 °C, which is attributed to the primary reduction step of RuO 2 species that interacts weakly with the supports. 26 The reduction peak near 430 °C may be due to the reduction of ruthenium oxide species formed with a stronger interaction with the supports.…”

Recent advancements in catalytic conversion pathways for synthetic jet fuel produced from bioresources

“…Co and FE catalysts were also found to have higher Ru dispersion than on a monometallic Ru/Al2O3 catalysts and show significant high catalytic activity [116]. Both bimetallic catalysts displayed the highest CO conversion than Ru/Al2O3 despite having lower Ru loading.…”

A review of the thermochemistries of biomass gasification and utilisation of gas products

“…The reaction temperature and pressure are comparable with alcohol synthesis from syngas, while Co-based catalysts are often employed for the reaction owing to a good reactivity balance and price. 257 In general, two major mechanisms, carbide and CO insertion, are believed to progress (Fig. 10).…”

“…Comparatively a high CO conversion (88%) was achieved at a comparatively low temperature of 200 °C. Liuzzi et al 257 reported that bimetallic Ru–Co/Al 2 O 3 allowed the formation of small Ru particles deposited on the surface of Co. It is known that the catalytic activity of Ru for hydrocarbon production by Fischer–Tropsch synthesis is higher than that of Co, while a drawback of Ru is a higher price compared to Co.…”
