Effects of Ag promotion for Co/Al2O3 catalyst in Fischer-Tropsch synthesis

Metal-organic framework (MOF)-derived catalysts for Fischer-Tropsch synthesis: Recent progress and future perspectives

“…The mild temperature, good selectivity towards C 5 + and relatively high stability of cobalt-based catalysts make them more advantageous than Fe-based FTS catalysts [78] . Because of their relatively high cost, cobalt-based catalysts are often supported on oxides of Al, Si or Ti to make them costeffective [79] . The activities of Co-based catalysts on these supports are affected by their reducibility and the extent to which the active cobalt sites are dispersed [80] .…”

Highly Dispersed CoO Embedded on Graphitized Ordered Mesoporous Carbon as an Effective Catalyst for Selective Fischer–Tropsch Synthesis of C5+ Hydrocarbons

“…Conventionally, various oxide materials such as SiO 2 , Al 2 O 3 , and TiO 2 are used to support Co-based catalysts. SiO 2 and Al 2 O 3 are preferentially used owing to their large surface areas, abrasion resistance, and excellent mechanical properties ( Bustamante et al, 2020 ; Wolf et al, 2020 ; Xu et al, 2020 ). However, the relatively strong interaction between cobalt oxide and the support leads to the generation of irreducible substances, such as CoAl 2 O 4 or Co 2 SiO 4 ( Bustamante et al, 2020 ; Li et al, 2020 ).…”

Terahertz pulsed imaging as a new method for investigating the liquid transport kinetics of α-alumina powder compacts

“…Solid catalysts are used in a wide range of applications, such as steam reforming (Nichele et al, 2012;Bej et al, 2014), vehicle emissions control (Chen et al, 2018), ammonia synthesis (Zhou et al, 2013), Fischer-Tropsch synthesis (Louyot et al, 2018;Xu et al, 2020) and hydrogenation processes (Jadhav et al, 2014;Segobia et al, 2019;Li et al, 2020) to name a few. Such catalysts usually have a porous structure to maximise their surface area per unit of reactor volume (Sosna et al, 2020).…”
