متن کاملFischer-Tropsch Synthesis of Hydrocarbons Using Iron-Mordenite Catalysts
Fischer-tropsch catalysts with high activity and selectivity for olefins were produced using mordenite type SiO2/Al2O3= 12, 20, 28, 62 zeolite supported iron carbonyl compounds and were characterized by X-ray powder diffraction. The adsorptionof volatile Fe(CO)5 on the support surface was carried out under vacuum at room temperature. Reduction les...
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 کاملEffects of Zn, Cu, and K promoters on the structure and on the reduction, carburization, and catalytic behavior of iron-based Fischer–Tropsch synthesis catalysts
Zn, K, and Cu effects on the structure and surface area and on the reduction, carburization, and catalytic behavior of Fe–Zn and Fe oxides used as precursors to Fischer–Tropsch synthesis (FTS) catalysts, were examined using X-ray diffraction, kinetic studies of their reactions with H2 or CO, and FTS reaction rate measurements. Fe2O3 precursors initially reduce to Fe3O4 and then to metallic Fe (...
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...
