Fe:Co/TiO2 bimetallic catalysts for the Fischer–Tropsch reaction

On the structural, textural and morphological features of Fe-based catalysts supported on polystyrene mesoporous carbon for Fischer–Tropsch synthesis

“…Silica, alumina, molecular sieves, titania, zirconia, carbon and zeolites have been the most studied supports for FTS catalysts [1][2][3][4][5][6][7][8][9][10][11]. Iron forms mixed oxides when supported on silica or alumina due to the influence of strong metal−support interactions, which are difficult to reduce and to allow the formation of the active Fe carbide [12][13][14][15].…”

“…Catalysts for the FTS reaction are mostly based on iron or cobalt [1,7]. Fe-oxides promoted with Cu as a reduction promoter, K as a chemical promoter and SiO 2 as a structural promoter are common iron-based catalysts used at the industrial scale [7].…”

“…The Fischer-Tropsch Synthesis (FTS) is a route to convert CO and H 2 (synthesis gas) into a wide variety of hydrocarbons and energy [1][2][3]. The products of the reaction are considered clean liquid fuels and chemical feedstocks with low methane and low oxygenated content, high alkane/alkene ratio and high wax or C 5 -C 10 content [2,4].…”

Effect of preparation method on catalytic performance, structure and surface reaction rates of MgO supported Fe–Co–Mn catalyst for CO hydrogenation

“…Cobalt is considered the most favorable metal for the synthesis of longchain hydrocarbons from synthesis gas due to its high activity per weight of metal compared to Fe, high selectivity to linear paraffins, high stability toward deactivation by water (a by-product of the FTS process), low water-gas shift activity and low price compared to noble metals such as Ru, Re, or Pt [4,7]. Both Co and Fe are typically used when combined with a range of supports and promoters that permit further control over the product spectrum [8]. It has been reported in the literature that addition of mixture of two active FTS metals can produce catalysts with chemical, physical and catalytic properties that are not directly related to knowledge of the properties of the separate metals [9][10][11][12].…”

Spatial Heterogeneity and Imperfect Mixing in Chemical Reactions: Visualization of Density-Driven Pattern Formation

“…An approach to improve the selectivity of the classical Fischer-Tropsch (FT) process for conversion of synthesis gas to hydrocarbons involves the use of a bifunctional catalyst system containing a metal catalyst (FT catalyst) combined with a support. There has been renewed interest in recent years in FT synthesis, especially for the selective production of petrochemical feedstocks such as ethylene, propylene, and buthylene (C 2 -C 4 olefins) directly from synthesis gas [1][2][3][4][5][6][7]. Compared to other metal catalysts for Fischer-Tropsch (FT) synthesis, an iron-based catalyst is distinguished by higher conversion, selectivity to the lower olefins, and flexibility to the process parameters [8,9].…”
