“…On the other hand, mesoporosity decreases acidity and modifies selectivity owing to its reduction of overcracking and MSI. By carefully tuning both acidity and mesoporosity, the FT process can be selectively directed to hydrocarbons in the gasoline − or diesel range.…”

“…Chemical treatments have been proposed in order to generate favorable mesoporosity of zeolite supports, for example, solvent-free in situ synthesis, sequential dealuminization–desilication, alkaline treatment, ,, soft template, steam-assisted crystallization, and delamination . All of these methods were reported to result in an increase in CO conversion and selectivity toward hydrocarbons in the liquid range at the expense of CH 4 selectivity.…”

Fischer–Tropsch (FT) synthesis is an important reaction for the alternative production of high-quality liquid fuels, which promote sustainable development by enabling economical decarbonization. The one-stage FT process involves both hydrocarbon growth and hydrocracking/isomerization in a single step and is more energy and cost efficient than the two-stage process. Bifunctional catalysts, composed of acid and metal sites, are needed in order to achieve one-step synthesis. In this review, we discuss the state of the art concerning the use of bifunctional catalysts for the one-stage FT process, focusing on the effect of metal and acid sites on the catalytic performance. Several supports with potential utility for the one-stage FT process were analyzed, including zeolites, clays, alumina, silica, aluminosilicates, and carbons, and the advantages and disadvantages of each are evaluated.

“…FTS is an effective process for the conversion of syngas into clean liquid fuels (gasoline, diesel fuel, and jet fuel) and valuable chemicals (light olefins and aromatics) [39][40][41][42][43][44][45][46][47][48][49]. It is a stepwise polymerization reaction and the products generally follow an Anderson-Schulz-Flory (ASF) distribution, which is inherently wide and unselective [50][51][52][53][54][55].…”

Capsule catalysts composed of pre-shaped core catalysts and layer zeolites have been widely used in the tandem reactions where multiple continuous reactions are combined into one process. They show excellent catalytic performance in heterogeneous catalysis, including the direct synthesis of middle isoparaffins or dimethyl ether from syngas, as compared to the conventional hybrid catalysts. The present review highlights the recent development in the design of capsule catalysts and their catalytic applications in heterogeneous catalysis. The capsule catalyst preparation methods are introduced in detail, such as hydrothermal synthesis method, dual-layer method, physically adhesive method and single crystal crystallization method. Furthermore, several new applications of capsule catalysts in heterogeneous catalytic processes are presented such as in the direct synthesis of liquefied petroleum gas from syngas, the direct synthesis of para-xylene from syngas and methane dehydroaromatization. In addition, the development in the design of multifunctional capsule catalysts is discussed, which makes the capsule catalyst not just a simple combination of two different catalysts, but has some special functions such as changing the surface hydrophobic or acid properties of the core catalysts. Finally, the future perspectives of the design and applications of capsule catalysts in heterogeneous catalysis are provided.

“…Direct synthesis of gasoline‐ranged (C 5 −C 11 ) hydrocarbons for automotive fuels from syngas is a promising pathway for the increasing energy demands. A rational strategy is to combine the F‐T catalyst with an acidic zeolite to assemble a bifunctional catalyst via the physical mixing, metal impregnation, zeolite encapsulation,, physical sputtering, and other routes . The selectivity of C 5 −C 11 ranged isoparaffins can be enhanced as high as more than 55 %, even higher than the predicted value of 45 % for all C 5 −C 11 hydrocarbons from ASF law.…”

As a century-old classical reaction, Fischer-Tropsch (F-T) synthesis is undergoing new developments especially in its applications of producing jet fuel, olefins, aromatics and oxygenated chemicals, which are completely different from the conventional F-T product, gasoline, diesel and wax. Producing above new products is not obeying famous ASF distribution law, requiring revolutionary design of new F-T catalysts and reaction pathways. A mass of new research directions on F-T synthesis for these liquid fuels and high-value chemicals are successfully proposed. This review spotlights recent new advances based on F-T synthesis for non-automotive applications, and discusses its new possible directions in future.Jet fuel, composed by hydrocarbons with a carbon number range from 8 to 16, is employed for driving gas-turbine engines in aircraft. It offers the propulsive energy for flight, and primary [a] Dr.
