Low acidity ZSM-5 supported iron catalysts for Fischer–Tropsch synthesis

Synthesis of Highly Stable Graphene‐Encapsulated Iron Nanoparticles for Catalytic Syngas Conversion

“…Obviously, the yield of more useful products (C 2 ‐C 4 olefins and C 5+ hydrocarbon) over Fe NPs with graphene encapsulation is much more than that of bare Fe 2 O 3 NPs catalysts. And its STY is also comparable to some other iron‐based catalysts even without any support and promoters . Detailed catalytic performances of both samples on syngas conversion at 40 th h were shown in Table S1 (Supporting Information).…”

“…Many strategies based on surface passivation have been developed to stabilize nanometal species by being confined in metal‐organic framework (MOF) supporters or coating organic molecules, polymers, or oxides, etc . These treatments do protect metal nanoparticles (NPs) from oxidizing in air or burning in H 2 O, but the coatings become a barrier to block effective charge transfer between the catalysts and reagents during the catalytic reactions.…”

“…Iron metal is one of the most promising catalysts for converting syngas (H 2 /CO) from feedstocks (natural gas, coal, biomass, etc.) to liquid fuels . Carbon materials not only act as support for distribute the NPs in Fischer‐Tropsch reaction but also are believed to regulate the catalytic performance through the confinement effect .…”

Cobalt Based Catalysts Supported on Two Kinds of Beta Zeolite for Application in Fischer-Tropsch Synthesis

“…This process leads to the production of sulfur and nitrogen free fuels and other valuable chemical compounds from the synthesis gas (the mixture of CO and H 2 ). The most known catalysts of the Fischer-Tropsch reaction are metal oxides (Fe, Co, Ru, Ni), which are often supported on Al 2 O 3 , SiO 2 , mesoporous silica and zeolites [1][2][3][4][5][6][7][8][9][10]. Cobalt catalysts are more widely used in FTS, which is related to both their higher selectivity for paraffins [23][24][25].…”

Preparation and characterization of promoted Fe–Mn/ZSM-5 nano catalysts for CO hydrogenation

“…The main phases were Fe 2 C (hexagonal), FeC (orthorhombic), Fe 3 O 4 (cubic). It was reported that oxide phases are active in CO hydrogenation and carbides phase's produces olefins [36,37]. According to the obtained results, after reactor testing the specific surface area and pore volume of nano catalysts were decreased ( Table 2).…”
