Nanopartículas de ouro suportadas em óxidos mistos de cério e ferro para a redução de NO por CO
… of Fe inserption into the CeO2 structure. Iron incorporation changed the CeO2 reducibility, reduced the crystallite size and increased the concentration of oxygen vacancies. Consequently, doping had effect on the performance of the catalysts in the redox reaction between NO and CO. As the …

ENHANCING GAS PHASE FISCHER-TROPSCH SYNTHESIS CATALYST DESIGN
… in the development of a Fe based catalyst with Co as a co catalyst, and Ru and ZnO as promoters. The role of Cu and K as promoters and the effect of SiO<sub>2</sub> as an alternate support to gamma- Al<sub>2</sub>O<sub>3</sub> were also investigated. A series of Fe-based catalysts for …

Effect of ammonia co-feeding on oxygenates over K-Mo2C in the Fischer-Tropsch synthesis
… long chained waxes and transportation fuels, is competing with fuels derived from crude oils and its profitability is therefore dependent on the global oil price. However, increasing the value of synthesized products could render the profitability of the FTS independent of fluctuations in the oil …

Development of a Kinetic Model for Low Temperature Fischer-Tropsch Synthesis
… reaction in which syngas, a mixture of CO and H2, is converted to hydrocarbon products ranging from methane to wax when low temperature conditions are used. Subsequent product upgrading steps allow high quality liquid fuels to be obtained which are clean burning. This will help to …

Supported Cobalt Oxide Catalysts for the Preferential Oxidation of Carbon Monoxide: An in situ Investigation
… in this thesis has placed great focus on Co3O4-based catalysts for producing CO-free H2-rich gas streams for power generation using proton-exchange or polymer electrolyte membrane fuel cells (PEMFCs). The removal of CO (0.5 – 2%) is essential as it negatively affects the performance of the …

A CFD Model for a Fixed Bed Reactor for Fischer Tropsch Reaction using Ansys
Fischer-Tropsch (FT) is a process which can convert synthesis gas derived from natural gas, coal or even biomass to a variety of products including saturated and unsaturated hydrocarbon chains, while keeping the emission of greenhouse gases minimum. Among various types of reactors used for …

Genetic Analysis of Crossover Defective Mouse Spermatocytes Reveals Discrete Crossover Precursor Intermediates
… organisms, like humans and mice, there are two copies of each chromosome, one from each parent. However, the germ cells of these organisms, the oocytes, and the sperm, have only one copy of each chromosome, thus ensuring that when haploid oocytes and sperm fuse to form a zygote, a diploid number …

Metallic cobalt derived from cobalt nitrides for Fischer-Tropsch Synthesis
… a catalytic surface polymerisation reaction that converts synthesis gas, a mixture of carbon monoxide (CO) and hydrogen, into long chain hydrocarbons, namely α-olefins and n-paraffins. The product selectivity of this reaction is dependent on the nano effects of the catalyst used in addition to the …
