Effects of promoters and calcination conditions on the catalytic performance of iron–manganese catalysts for Fischer–Tropsch synthesis

Selectivity Modeling of Synthesis Gas Reaction over the Iron Catalyst and Optimization Products

“…Also, since the R 2 -Perd value is closer to 1, we can use the models to predict the products selectivity in different values of temperature, pressure and H 2 /CO ratio. For example, in the reference [29], the total selectivity of hydrocarbons on the catalyst 50% Fe/50%Mn/6%K at P=1atm, H 2 /CO=2, T=250°C was obtained to be 94.5, which in the model was obtained in this study with less than 2% difference, being 96.38.…”

A review of advanced catalyst development for Fischer–Tropsch synthesis of hydrocarbons from biomass derived syn-gas

“…The addition of chemical promoters is important for the optimisation of active and selective FT catalysts. 24…”

“…Based on the given information, it can be concluded that the use of 2 wt (%) K provides the optimum catalytic performance for synthesis gas conversion to light olefins and better olefins selectivity. 24 The effect of different transition metals (Zr, Mn, Cr, Mo, Ta and V) on the catalytic performance of Fe-Cu based catalysts has also been explored, which showed that the utilisation of these transition metals promotes both CO hydrogenation and WGS activity. 93 Further studies suggested that the addition of these transition metal promoters increased the iron dispersion, but did not reduce the BET surface area or reducibility of catalyst.…”

Modeling and operating conditions optimization of Fischer–Tropsch synthesis in a fixed-bed reactor

“…and various supports (SiO 2 , TiO 2 , Al 2 O 3 , La 2 O 3 , ZSM-5 zeolite) [7,8]. Mixed metal catalysts are often capable of activity, selectivity, or have a stability, that is unobtainable with a single component [9] and it is believed that bimetallic catalysts system due to the thermodynamic and kinetic limitations of the reaction are more able to raise the value of the light olefins [10][11][12][13].…”
