“…They have also reported that these interactions have great influence on the catalytic activity in the studied reaction. Todic et al [20] reported, that the increase of the reaction temperature and ratio between CO and H 2 increase the selectivity to methane production and leads to decrease towards C 5? production.…”

Monometallic iron supported catalysts were prepared by the impregnation method and tested in Fischer-Tropsch (F-T) synthesis. The activity tests performed in the studied reaction showed that the composition of the catalyst strongly influences the reactivity of the catalytic systems in the F-T reaction. It was also found that the system which showed the highest content of iron species on the catalyst surface exhibited the highest yield in F-T reaction. In addition, the most active catalyst also showed high specific surface area, high total acidity value and the highest amount of iron species on the catalyst surface. The analysis of the liquid product of F-T synthesis confirmed the occurrence of aliphatic, branched and unsaturated linear hydrocarbons.

“…The pilot test results showed that the iron based catalysts which acclimatized to the radio of 1.5 is favorable, so in this paper, H2/CO ratio of the shifted syngas is assumed to be 1.5. Based on the researches of catalysts performance in FT synthesis, Fe based catalyst and slurry reactors are employed for this study [37,38]. In FT synthesis, CO and H2 react exothermically in the presence of the catalysts to produce hydrocarbons, ranging from methane to high molecular weight wax (>Cn42).…”

Abstract-Integrated systems of FT liquids processes and waste energy utilization based on Shell, GSP and GE gasification are designed and simulated. The results show that under the condition of 1 000 t/hr coal feedstock, the yields of the liquids, including diesel, naphtha and LPG, are 205.2t/hr, 73.2t/hr and 40.1t/hr, respectively based on shell; 205.1t/hr, 73.2t/hr and 40.1t/hr, respectively based on GSP; 183.8t/hr, 65.6t/hr and 35.9t/hr respectively based on GE. However, the electricity generation equivalent to about 2% of coal thermal value cannot meet the power needs of the three systems. Based on LHV, the highest system thermal efficiency of 47.7% comes from the system based on Shell. The lowest system thermal efficiency, resulting from the system based on GE, has decreased 7.1% compared with that of the system based Shell. The proportion of carbon capture to the total carbon entering the systems is 58.7% (for the system based on Shell), 58.6% (for the system based on GSP) and 59.5% (for the system based on GE), respectively.

“…Natural resources, such as coal, natural gas and biomass, can be converted into liquid hydrocarbon fuels via the Fischer-Tropsch synthesis (FTS) reaction [2]. Reactants (CO + H2) through this reaction are converted to an array of long chain molecules, mainly consisting of nparaffins and 1-and 2-olefins:…”

The MgO-supported Fe-Co-Mn catalysts, prepared using co-precipitation procedure, were tested for production of light olefins via CO hydrogenation reaction. The effect of a range of drying conditions including drying temperature and drying time on the structure and catalytic performance of Fe-Co-Mn/MgO catalyst for Fischer-Tropsch synthesis was investigated in a fixed bed micro-reactor under the same operational conditions of T = 350 °C, P = 1 bar, H2/CO = 2/1, and GHSV = 4500 h -1 . It was found that the catalyst dried at 120 °C for 16 h has shown the best catalytic performance for CO hydrogenation. Furthermore, the effect of drying conditions on different surface reaction rates was also investigated and it was found that the precursors drying conditions influenced the rates of different surface reactions. Characterization of catalyst precursors and calcined samples (fresh and used) was carried out using powder X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDS), Brunauer-Emmett-Teller (BET) measurements, Temperature Programmed Reduction (TPR), Thermal Gravimetric Analysis (TGA), and Differential Scanning Calorimetry (DSC). Characterization results showed that different investigated variables (drying conditions) influenced the structure, morphology and catalytic performance of the ternary catalysts.
