Potassium-decorated active carbon supported Co-Mo-based catalyst for water-gas shift reaction

Activated Carbon‐Supported Mo‐Co‐K Sulfide Catalysts for Synthesizing Higher Alcohols from CO2

“…As a tandem reaction, the first step of CO 2 hydrogenation is CO 2 conversion to CO by consuming H 2 , and the second step is CO hydrogenation for the synthesis of organic products. It is usually suggested that the WGS/RWGS reaction consists of a series of quick elementary reactions, and it can reach the thermodynamic equilibrium state relatively easily . However, the consecutive step of CO hydrogenation is a kinetic control reaction, which would make the final product distribution apart from the thermodynamic equilibrium to some extent.…”

“…However, MoS 2 ‐based catalysts are still the most competitive choice due to their lower selectivity to hydrocarbons compared with other Mo catalysts . Moreover, MoS 2 ‐based catalysts doped with transition metals (Co or Ni) have also been applied effectively in water‐gas shift (WGS)/RWGS , , which means that these catalysts have potentials in CO 2 conversion and utilization.…”

Catalysts design for higher alcohols synthesis by CO2 hydrogenation: Trends and future perspectives

“…Besides, the hydrocarbon selectivity (CO free) decreased. This trend was explained by assuming that the WGS/RWGS reactions consist of a series of fast elementary reactions that reach thermodynamic equilibrium relatively fast [178], while the consecutive CO hydrogenation is kinetically-controlled. Additionally, the effect of feed composition was also studied [140].…”

Sour gas shift process over sulfided Co–Mo–K catalysts supported on carbon material — Support characterization and catalytic activity of catalysts

“…Whereas literature concerning molybdenum-based catalysts (Co-Mo and Ni-Mo) on carbon supports which are used mainly in HDS processes [27] and in higher alcohol synthesis [28] the reports on the application of this type of catalysts in SGS process are relatively sparse. To the best of our knowledge only Liana et al studied Co-Mo systems supported on carbon support as SGS catalysts [29]. Active carbon (AC) was used as a support material which was only washed in HNO 3 and distilled water and then dried.…”
