Correlation between Fischer-Tropsch catalytic activity and composition of catalysts
This paper presents the synthesis and characterization of monometallic and bimetallic cobalt and iron nanoparticles supported on alumina. The catalysts were prepared by a wet impregnation method. Samples were characterized using temperature-programmed reduction (TPR), temperature-programmed oxidation (TPO), CO-chemisorption, transmission electron microscopy (TEM), field emission scanning electr...
متن کاملPromoted Iron-Based Catalysts for the Fischer–Tropsch Synthesis:Design, Synthesis, Site Densities, and Catalytic Properties
Iron-based catalysts were prepared by using promoters (K, Ru, Cu) and synthesis and activation protocols that inhibit sintering of oxide precursors and favor the nucleation of small Fe carbide crystallites. The effects of promoters on reduction/carburization behavior, on Fischer–Tropsch synthesis (FTS) rates, and on the number of CO binding sites formed during reaction were examined by combinin...
متن کاملTechnology Development for Iron and Cobalt Fischer-Tropsch Catalysts
A cobalt catalyst (25%Co/γ-Al2O3, prepared by slurry phase impregnation) was used in a fixed bed reactor under a pressure/density tuned supercritical fluid mixture of n-pentane/nhexane. By using an inert gas as a balancing gas to maintain a constant pressure, the density of the supercritical fluid could be tuned near the supercritical point while maintaining constant space velocity within the r...
متن کاملFischer Tropsch Synthesis: A Comparison of Iron and Cobalt Catalysts
Following WW II, it appeared that there would be a severe shortage of crude oil so that U.S. organizations initiated work on Fischer-Tropsch synthesis (FTS). Over a ten year period, the U.S. Bureau of Mines was budgeted $85 million for work on direct and indirect coal liquefaction. These funds would represent more than a billion dollars in today’s marketplace. A large (75 bbl/day) FTS pilot pla...
متن کاملNanoscale 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...
