Nanoscale Design of Supported Iron Fischer-Tropsch Synthesis Catalysts
Introduction The preparation and characterization of nanophase materials has received considerable attention in recent years, given their potential for improved performance as catalysts, high-strength materials, and semiconductor devices. For example, a recent breakthrough by Sun et al. (1) in the synthesis of highly-dispersed, silica-supported iron-platinum (FePt) bimetallic nanoclusters of co...
متن کاملEffect of calcium promoter on nano structure iron catalyst for Fischer–Tropsch synthesis
The Fischer-Tropsch synthesis (FTS) has been recognized as a heterogeneous surface-catalyzed polymerization process. During this process, CHx monomers formed via the hydrogenation of adsorbed CO on transition metals produce hydrocarbons and oxygenates with a broad range of chain lengths and functional groups. A series of Fe/Cu Fischer-Tropsch synthesis catalysts incorporated with a calcium prom...
متن کاملReactions of Olefins Added during Fischer-Tropsch Synthesis over Supported Cobalt Catalyst
The control on product distributions in Fischer-Tropsch synthesis by feeding olefins in the n-paraffin solvent over a 20 wt.% Co/SiO2 catalyst under the typical reaction conditions of 503K, 2.1MPa, H2/CO = 2, and co-fed olefins 16 mol% in CO base in a trickle bed reactor has been studied. The selected co-fed olefins include 1-octene, 2-octene and 1-dodecene. Results showed that the addition of ...
متن کاملPreparation of a Novel Super Active Fischer-Tropsch Cobalt Catalyst Supported on Carbon Nanotubes
The potential of carbon nanotubes (CNT) supported cobalt catalysts for Fischer-Tropsch (FT) reaction is shown. Using the wet impregnation method cobalt on carbon nanotubes catalysts were prepared with cobalt loading varying from 15 to 45 wt. %. The catalysts are characterized by different methods including: BET physisorption, X-ray diffraction, hydrogen chemisorption, and temperature-progra...
متن کاملKCl Promoted Cobalt-iron Nanocatalysts Supported on Silica: Catalytic Performance and Characterization in Fischer-Tropsch Synthesis
The SiO2 supported cobalt-iron nano catalysts were prepared by the sol-gel method. This research investigated the effects of (Co/Fe) wt.%, different Co/Fe ratio at different temperature and loading of KCl wt.% for Fisher-Tropsch synthesis (FTS). The results were showed that the catalyst containing 50 wt.% (Co/Fe)/SiO2 (Co/Fe ratio is 70/30) which promoted with 0.6 wt.% KCl is an optimal nano ca...
