Aqueous-phase Fischer-Tropsch synthesis with a ruthenium nanocluster catalyst.
Introduction Hydrogenation of carbon monoxide to produce hydrocarbons, normally called Fischer-Tropsch synthesis (F-T synthesis), is one of the most important hydrogenation reactions due to its potential for the intermediate production of hydrocarbon fuels in the “postpetroleum” era. The reaction is favored at low-temperature and therefore reducing the particle size of the catalyst to several n...
متن کاملFischer–Tropsch synthesis on a model Co/SiO2 catalyst
A model Co/SiO2 catalyst was prepared by depositing cobalt on silica films in ultrahigh vacuum conditions. Fischer–Tropsch synthesis was carried out at a total pressure of carbon monoxide and hydrogen between 0.33 and 1.0 bar. The effects of reaction temperature and pressure on kinetics and chain growth probability were investigated. The turnover frequency, activation energy, and product distri...
متن کاملThe optimally performing Fischer-Tropsch catalyst.
Microkinetics simulations are presented based on DFT-determined elementary reaction steps of the Fischer-Tropsch (FT) reaction. The formation of long-chain hydrocarbons occurs on stepped Ru surfaces with CH as the inserting monomer, whereas planar Ru only produces methane because of slow CO activation. By varying the metal-carbon and metal-oxygen interaction energy, three reactivity regimes are...
متن کاملSynthesis and Characterization of Fe-Catalyst for Fischer-Tropsch Synthesis Using Biosyngas
Fischer–Tropsch technology has gathered renewed interest in the energy industry in recent times for synthesis of diesel and gasoline. The synthesis of linear hydrocarbon diesel fuel (having high cetane number) through Fischer–Tropsch synthesis (FTS) reaction requires syngas with high H2/CO molar ratio. Producer gas obtained from biomass gasification has low H2/CO ratios, with significant conten...
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...
