Fischer–Tropsch synthesis: effect of silica on hydrocarbon production over cobalt-based catalysts

Profound synergetic effect of metal oxide promoters and TiO2–SiO2 binary support in cobalt Fischer‐Tropsch catalyst

“…The addition of CeO 2 as a promoter in accordance with some reports enhanced catalyst activity more than other catalysts because it widely demonstrates oxygen mobility . CeO 2 and ZrO 2 as metal oxide promoters has been modified electron density of metallic cobalt that enhance Bridge‐type CO adsorption and consequently C‐O dissociation …”

“…[22] CeO 2 and ZrO 2 as metal oxide promoters has been modified electron density of metallic cobalt that enhance Bridge-type CO adsorption and consequently C-O dissociation. [15] Furthermore, similar results have been observed for the addition of a promoter to cobalt catalysts supported on SiO 2 . According to Table 4, CeO 2 and ZrO 2 improved the behavior of the RC/S catalyst and V 2 O 5 promoter in a similar manner as RC/T catalyst, which demonstrates converse results on cobalt catalyst supported on SiO 2 .…”

“…For FTS, it is subjected to maximization of the catalyst activity and selectivity. In the previous study, the catalyst with support, including Al 2 O 3 and SiO 2 , has higher activity . In the present work, the main focus is on enhancing cobalt catalytic behavior by improving the catalyst activity and selectivity simultaneously toward long‐chain hydrocarbon.…”

“…In the previous study, the catalyst with support, including Al 2 O 3 and SiO 2 , has higher activity. [15] In the present work, the main focus is on enhancing cobalt catalytic behavior by improving the catalyst activity and selectivity simultaneously toward long-chain hydrocarbon. According to literature reviews, different paths have been followed for achieving higher hydrocarbon production.…”

Application of Machine Learning to Fischer–Tropsch Synthesis for Cobalt Catalysts

“…All of the above elements are the most popular carriers that increase the reaction surface area . All other additives were combined into one parameter (other): zirconium, − manganese, sodium, magnesium oxide, phosphorus, metallic aluminum, bismuth, hydroxyapatite, iron, cerium, and cadmium …”
