The Fischer-Tropsch Synthesis (FTS) is a significant catalytic chemical reaction that produces ultra-clean fuels or chemicals with added value from a syngas mixture of CO and H2 obtained from biomass, coal, or natural gas. The presence of sulfur is not considered good for producing liquid fuels for(FTS). In this study, we reveal that the presence of sulfur in ferric sulfate Fe2(SO4)3 MOF provides the high amount, 52.50% of light hydrocarbons in the carbon chain distribution. The calcined ferric nitrate Fe(NO₃)₃ MOF reveals the highest 93.27% diesel production. Calcination is regarded as an essential factor in enhancing liquid fuel production. Here, we probed the calcination effect of Metal Organic Framework (MOF) on downstream application syngas to liquid fuels. The XRD results of MOF. N and P. MOF.N shows the formation of the active phase of iron carbide (Fe5C2), considered the most active phase of FTS. The scanning electron microscopy (SEM) images of iron sulfate MOF catalyst (P.MOF.S) reveals that the existence of sulfur creates pores inside the particles due to the reaction of free water molecules with the sulfur derivate. The surface functional groups of prepared MOFs and tested MOFS were analyzed by Fourier transforms infrared spectroscopy (FT-IR). The thermal stability of prepared MOFS was analyzed by Thermo gravimetric analysis (TGA). The surface areas and structural properties of the catalysts were measured by N2-Physiosorption technique.

“…So far, SiO 2 , Al 2 O 3 , CeO 2 , ZrO 2 , TiO 2 , SiC and several carbon materials have been used as carriers in HTFTS. [37][38][39][40][41][42][43] The performance strongly depended on the origin and properties of the support material as well as the application method of the active materials.

“…Although results on supported Fe catalysts are available, primarily high‐temperature FTS (HTFTS, ϑ >260 °C) has been addressed and, therefore, HA formation has been widely neglected.

For sustainable production of chemicals like hydrocarbons and oxygenates from renewable carbon sources and electricity Fischer‐Tropsch synthesis is focused in current research. Aiming for this purpose, the development of supported powdered and shaped catalysts for low‐temperature Fischer‐Tropsch synthesis of value‐added higher alcohols was addressed in this study. Promising support materials like α‐Al2O3, SiO2, ZrO2 and SiC were assessed and the influence of electrochemical promoters on product formation was investigated. The results show an outstanding promoting effect of lithium on conversion and alcohol selectivity. A beneficial synergistic effect occurred for the combination of 1 % Li and Cu each and could be exploited both for supported powdered and shaped catalysts. Furthermore, effects of surface, shape, porosity and Fe content on pellet catalysts were investigated. Exploiting the beneficial effects found, the first monometallic shaped Fe‐based catalyst ‑ outperforming the state‐of‐the‐art monometallic Fe powder catalysts in conversion and selectivity ‑ is presented.
