The influence of the Co/SBA–15 catalyst texture, such as pore size and pore length on Fischer–Tropsch (FT) Synthesis, was investigated in this paper. The morphology, structure, and microstructures of Co/SBA–15 catalysts were characterized by SEM, Brunauer–Emmett–Teller (BET), TPR, HRTEM, and XRD. The experimental results indicated that the increase of pore size could improve the activity of the Co/SBA–15 catalyst, and the further increase of pore size could not significantly promote the activity. Moreover, it was also found that the pore length of the Co/SBA–15 catalyst played a key role in the catalytic activity. CO2 and C4+ selectivity were 2.0% and 74% during the simulated syngas (64% H2: 32% CO: balanced N2) FT over the Co/SBA–15 catalysts, and CO conversion rate and CH4 selectivity were 10.8% and 15.7% after 100 h time on stream.

Catalytically Active

In Fischer–Tropsch synthesis (FTS), cobalt carbide (Co2C) is not a catalytically active material, but rather an undesired cobalt phase associated with low catalytic performance.

Positive Effect

A series of solid solutions in the PdTe–PdBi system with general formula [Formula: see text]Bix ([Formula: see text], 0.5, 0.67) with the structure based on the NiAs type were synthesized by a high-temperature ampoule technique. These compounds, along with their parent binaries, PdTe and PdBi, were tested as promoters for the standard Co/Al2O3 catalytic system in the Fischer–Tropsch synthesis. It is shown that the addition of PdTe and [Formula: see text]Bix to the standard catalyst increases both yield and selectivity with respect to the liquid phase. At the same time, the addition of PdBi does not only improve catalytic activity, but also slightly inhibits it. Another positive effect of the PdTe and [Formula: see text]Bix addition is the shift in the conversion products toward the diesel and wax fractions. Chemical bonding analysis in orbital and direct space indicates that the addition of Bi to PdTe might increase the localized bonding.
