“…Among the heterogeneous metal based catalysts that afford this transformation, those containing chromium, nickel, zinc, copper, cobalt and aluminum are the most studied [ 5 , 6 , 7 ]. However, iron could be considered as the optimum choice from a sustainable approach because it is cheap, earth abundant, and has relatively low toxicity [ 8 ]. Thus, in the last few years, some heterogeneous iron catalysts, that effectively promote this reaction, have been reported, e.g., iron doped mesoporous zeolites [ 9 , 10 ], a porous covalent triazine-based polymer containing iron oxide nanoparticles [ 11 ] and some iron-based poly(azomethine)s [ 12 , 13 , 14 ].…”

Commercial iron (II) phthalocyanine (FePc) was knitted with biphenyl using a Friedel–Crafts reaction to yield a micro-meso porous organic polymer (FePc-POP) with a specific surface area of 427 m2/g and 5.42% of iron loading. This strategy allowed for the direct synthesis of a heterogeneous catalyst from an iron containing monomer. The catalytic system, formed by the knitted polymer containing FePc and DMAP (4-dimethylamino pyridine) as base, results in an efficient heterogeneous catalyst in the cycloaddition of CO2 to epichlorohydrin to selectively obtain the corresponding cyclic carbonate. Thus, a TON (mmol substrate converted/mmol catalysts used) value of 2700 was reached in 3 h under mild reaction conditions (solvent free, 90 °C, 3 bar of CO2). The catalyst does not exhibit leaching during the reactions, which was attributed to the excellent stability of the metal in the macrocycle.

“…Conversion of biomass/coal‐based synthesis gas (i. e., syngas) or CO 2 ‐containing syngas may be applied to produce long chain hydrocarbons in a process called Fischer‐Tropsch synthesis (FTS), or light olefins in a process called Fischer‐Tropsch to olefins (FTO, also called FTTO), or even oxygenates such as alcohols . Light olefins (i. e., C 2 = ‐C 4 = ) contain two to four carbon atoms.…”

Development of Highly Selective Support for CO Hydrogenation to Light Olefins with Partially Passivated Iron Catalysts

To rule out disturbances from water‐soluble efficient promoters (e. g., K2O or combination of S/Na), a simplified iron/support catalyst system was employed to investigate novel supports for the catalytic conversion of syngas (CO+H2) to light olefins (FTO). A series of supports with nominal compositions of ZnAl2O4 ⋅ xAl2O3 (x=1, 2, 3) were prepared by coprecipitation and subsequent high temperature calcination at 1200 °C for 24 h to generate partially passivated ZnAl2O4 and Al2O3 phases, through which each formed component of a catalyst may minimize interactions among them and exhibit unique activity. Iron catalysts were prepared by incipient wetness of iron salts over these supports. At a total pressure of ca. 20 bar and a CO conversion of 35 %, a catalyst with a nominal composition of 15 %Fe/85 %(ZnAl2O4 ⋅ 3Al2O3) exhibits a surprising C2=‐C4= hydrocarbon distribution of 58 %, which reaches a huge increase by almost 100 % in comparison with iron catalysts over regular supports (e. g., carbon, gamma‐Al2O3, etc.). This catalyst demonstrates the 1200 °C passivated ZnAl2O4 ⋅ 3Al2O3 as probably the most selective support material for iron‐based FTO catalysts. At CO conversion of 35 %, the contents of ethylene in C2, propylene in C3, and butylene in C4 products achieve extraordinary values of 82 %, 92 %, and 91 %, respectively.

“…Most recently, Bae et al [19] proposed a promising and cost-effective iron ore FT catalyst approach alternative to conventional precipitated low-temperature Fischer-Tropsch (LTFT) iron-based with comparable FT activity to other traditional FT catalysts [19]. However, the study was more appropriate for laboratory operations and did not consider the mechanical strength of the catalyst, which is crucial for upscaled fixed operations, as mentioned earlier.…”

Fischer-Tropsch (FT) synthesis has been studied in the literature as a greener pathway to cleaner and sustainable hydrocarbons production. However, the cost to upscale laboratory FT formulations to pilot scale is significantly expensive. This work proposes a cheaper and scalable low-temperature FT modified iron ore catalyst that is mechanically suited for fixed bed reactors. The mechanical strength reported in this investigation was three times more than commercial alumina spherical pellets and, therefore, suitable for pilot scale scenarios. A manufacturing cost analysis of iron ore was estimated to be US$38.45/kg using the CatCost model, and the conventionally prepared iron catalyst was US$71.44/kg using the same model. The manufacturing cost estimations of modified iron ore were found to be 46% cheaper than a conventional commercial iron catalyst. The catalytic performance of the modified iron ore catalyst showed a CO conversion of 72.1% ±4.24, with WGS and C5+ selectivity 48.6% ±1.96 and 83.2% ± 5.24, respectively. These findings were comparable (both in CO conversion and product selectivity) to the ones reported by other researchers.
