“…[62] However, there are several limitations to using the hydrothermal method to construct the core-shell catalyst. [63] Second, the strongly alkaline conditions used for zeolite synthesis and the vulnerability of the FT core catalyst (particularly that with the SiO 2 support, which can be destroyed in alkaline medium) further increase the difficulty of this method.

Fischer-Tropsch synthesis is a key reaction in the utilization of non-petroleum carbon resources, such as methane (natural gas, shale gas, and biogas), coal, and biomass, for the sustainable production of clean liquid fuels from synthesis gas. Selectivity control is one of the biggest challenges in Fischer-Tropsch synthesis. This Minireview focuses on the development of new catalysts with controllable product selectivities. Recent attempts to increase the selectivity to C5+ hydrocarbons by preparing catalysts with well-defined active phases or with new supports or by optimizing the interaction between the promoter and the active phase are briefly highlighted. Advances in developing bifunctional catalysts capable of catalyzing both CO hydrogenation to heavier hydrocarbons and hydrocracking/isomerization of heavier hydrocarbons are critically reviewed. It is demonstrated that the control of the secondary hydrocracking reactions by using core-shell nanostructures or solid-acid materials, such as mesoporous zeolites and carbon nanotubes with acid functional groups, is an effective strategy to tune the product selectivity of Fischer-Tropsch synthesis. Very promising selectivities to gasoline- and diesel-range hydrocarbons have been attained over some bifunctional catalysts.

“…Light isoparaffins can be produced from syngas on a hybrid (capsular) catalyst representing a mixture of the FT catalyst and zeolite [105]. The zeolite capsular catalyst with a core-shell structure was prepared using 10% Co/SiO 2 as core catalysts and HZSM-5 zeolite.…”

“…Until now, there are three kinds of bifunctional catalysts for direct synthesis of middle isoparaffin: physical mixture catalysts [12,13], zeolite-supported metal catalysts [14,15] and capsule or coated catalysts with the conventional FTS catalyst core and zeolite shell [16][17][18]. The physical mixture catalysts usually have a relatively low selectivity of middle isoparaffin due to its random hydrocracking/isomerization of long-chain hydrocarbons in acidic zeolite.…”

“…Zeolite with highly thermal stability, ordered structure, high acidity and shape selectivity has been applied widely as heterogeneous catalysts in the traditional petroleum-related processes and fine chemical industries [31][32][33]. So far, the zeolite membranecoated core catalysts are usually prepared by the hydrothermal synthesis method [22,34,35] or physically adhesive method [16,36]. However, the hydrothermal synthesis method produces generally a lot of waste water.…”

Please cite this article in press as: C. Xing, et al., Tunable isoparaffin and olefin yields in Fischer-Tropsch synthesis achieved by a novel iron-based micro-capsule catalyst, Catal. Today (2014), http://dx. a b s t r a c tA novel iron-based micro-capsule catalyst with interior Fe/Silica core and exterior H-ZSM-5 shell was synthesized via in-situ crystallization route on Fe/SBA-15 catalyst by using steam-assisted crystallization (SAC) process and evaluated for direct synthesis of middle isoparaffin from syngas in a fixed-bed reactor. Structure characterization indicated that the size of micro-capsule catalyst was about 1-2 m. According to activity test results, original Fe/SBA-15 catalyst exhibited a low selectivity of isoparaffin as 8.2%. But the as-prepared micro-capsule catalyst achieved an excellent performance for isoparaffin synthesis with the selectivity up to 46.5%. Meanwhile, the physical mixture catalyst (Fe/SBA-15 and H-ZSM-5) exhibited lower isoparaffin selectivity with 33.9% than that of the micro-capsule catalyst. The spatial confinement effect of the micro-capsule catalyst played an important role for the high selectivity of isoparaffin synthesis.
