“…Catalysts 2017, 7, 382 2 of 13 MIL-100 (Fe) achieved a complete conversion for CO being oxidized to CO2 at 255 °C [30], and its activity can be further improved. The noble metal catalysts containing Ag [33][34][35], Au [36,37], Pd [38], In [39] or Pt [40,41] have been used in the catalytic oxidation of CO to CO2 in the past few decades.…”

“…XRD patterns of pure α-Fe2O3 and Ag-Fe2O3 catalysts prepared by various methods are shown in Figure 1 (α-Fe2O3 was obtained by calcination of MIL-100 (Fe) at 430 °C for 2 h) [30]. It was found that all samples present two major diffraction lines at 2θ = 33.1° and 35.6°, which correspond to (104) and (110) lattice planes of α-Fe2O3 [3] (PDF No.…”

“…(ii) The synthesis process is the same as the synthesis of MIL-100 (Fe), except that a given amount of silver is added during the agitation process before hydrothermal treatment; the final product was named as Ag-MIL. (iii) The Fe 2 O 3 was used as the carrier, which derived from MIL-100 (Fe) with calcination for 2 h at 430 • C in a muffle furnace [30], and the silver was impregnated into the Fe 2 O 3 as before, while the final catalyst was denoted as Ag-Fe 2 O 3 . iv) Commercial Prussian blue (C 18 Fe 7 N 18 ) was used as the support, and the silver was loaded by the impregnation method as before which was denoted as Ag-PB.…”

Abstract:In this work, Ag-Fe 2 O 3 catalysts were successfully prepared using several different methods. Our main intention was to investigate the effect of the preparation methods on the catalysts' structure and their catalytic performance for CO oxidation. The catalysts were characterized by X-ray diffraction (XRD), N 2 adsorption-desorption, transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), H 2 -temperature program reduction (H 2 -TPR) and inductively coupled plasma optical emission spectroscopy (ICP-OES). Ag-Fe catalysts prepared by impregnating Ag into MIL-100 (Fe) presented the best catalytic activity, over which CO could be completely oxidized at 160 • C. Based on the characterization, it was found that more metallic Ag species and porosity existed on Ag-Fe catalysts, which could efficiently absorb atmospheric oxygen and, thus, enhance the CO oxidation.

The present work has focused on the modeling and selectivity of a mesoporous alumina-supported Fe-Ag-Ce, a new CO hydrogenation catalyst, in a fixedbed microreactor, at different operating conditions as follows: temperature (260 C-340 C), total pressure (2-11 bar), syngas ratio (1-3), and GHSV (1800-3600 hours −1 ). The effects of operating conditions and their influence on the CO conversion, C 5+ selectivity, and light olefins selectivity (light olefinity) were studied using response surface methodology. The products' selectivity was primarily controlled via the reaction conditions. The responses in this catalytic system were described adequately by modified mathematical models. The simultaneous effects of cerium and silver promoters increased the ratio of olefin to paraffin over the iron catalyst in the Fischer-Tropsch synthesis. Model graphs indicated that maximum amounts of light olefins obtained at T = 323 C, P = 10.36 bar, H 2 /CO = 1.5, and GHSV = 3219 hours −1 . Catalysts' characterization was administered via X-ray diffraction, temperatureprogrammed reduction, and the measurements of N 2 adsorption such as BET and BJH methods. Highlights• Response surface models were developed for product selectivity of Fischer-Tropsch.• Addison of promoter improved both CO conversion and reaction selectivity.• The simultaneous effects of using cerium and silver increased the amount of olefin.• Optimization is used to find the maximum of the desirable products.
