“…For preventing catalyst deactivation and enhancing catalytic performance, 1 g of fresh catalyst was reduced at atmospheric pressure and 723.15 K using H 2 (30 mL/min) for 30 hours. The reduction temperature was selected based on previous reports 24,25 . Automatic mass flow controllers (MFC) were applied to regulate the flow rate of H 2 and CO (99% purity) into the furnace.…”

In this paper, the effects of operating conditions on CO hydrogenation reactions were explored by statistical-based selectivity models in the presence of a γ-Al 2 O 3 supported Fe-Co bimetallic nanocatalyst. The temperature, pressure, and feed ratio varied in 1 to 7 bar, 573 to 663 K, 0.5 to 2, respectively; while the GHSV was 3000 h À1 in a fixed bed micro-reactor. Response surface methodology indicated that optimum conditions for the production of maximum olefins and minimum CH 4 , paraffin, and carbon dioxide involved T = 579 K, H 2 /CO = 1, and P = 1 bar. The increase in H 2 /CO, pressure, and temperature reduced olefin selectivity and raised the selectivity of paraffin, CH 4 , and carbon dioxide. SEM and BET techniques were used to characterize the catalyst.

“…The extension of this approach to F–T reaction can potentially provide an opportunity for enhancing hydrocarbon fuels yield and mitigating catalyst rapid deactivation because of carbonaceous deposits or interaction with water and carbon monoxide as poisons during the reaction. Recently, Sedighi and co‐workers developed a nanocatalyst of Co‐Fe‐resol supported over SiO 2 using co‐precipitation procedure. The resol was also obtained following an earlier method and also incorporated using the precipitation method.…”

SUMMARYThe valorization of municipal solid waste (MSW) into liquid fuels is a multi-beneficial global option for ensuring environmental and energy sustainability. The paper critically reviewed a wide range of recent literature on the potency, progress, and challenges associated with MSW upgrading into liquid fuels. Concise details on the various upgrading technologies involved such as gasification, pyrolysis, and syngas-to-fuels (i.e., syngas to gasoline and diesel) via a Fischer-Tropsch process were documented. Emphasis was critically given to the recent literature updates. The paper explored the role of heterogeneous catalyst systems in achieving the various processes with special considerations for optimizing fuel yield. Prospective technologies such as plasma gasification and nanoscale catalyst design with potentials to revolutionize the industry were also discussed.

“…Fe-Co bimetallic system allows to improve various physico-chemical properties significantly. For example, Fe-Co bimetallic system is characterized by high Curie temperature, large saturation magnetization, great magnetic permeability [2, 5 -9] and gives rise to a synergistic effect in catalysis [5,10].…”

Abstract. Metal-carbon nanocomposites consisting of FeCo alloy nanoparticles dispersed in a carbon matrix were synthesized by the thermal decomposition method of a precursor based on polyvinyl alcohol and metals salts. The synthesized powders were investigated by X-ray diffraction (XRD), X-ray fluorescent spectrometry (XRFS), transmission electron microscopy (TEM) and scanning electron microscopy (SEM). Surface characteristics of materials were measured by BET-method. The morphology and dispersity of metal nanoparticles were studied depending on the metals ratio in the composite.
