Book Fischer Tropsch Synthesis Catalysts and Catalysis

Download or read book Fischer Tropsch Synthesis Catalysts and Catalysis written by Burtron H. Davis and published by CRC Press. This book was released on 2016-04-06 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is based on a symposium held during the 248th American Chemical Society meeting that focused on use of the Fischer-Tropsch process in producing synthetic fuels. Its contents reflect the four dominant subjects of the meeting: catalyst preparation and activation, catalyst activity and reaction mechanisms, catalyst characterization and related reactions, and topics concerning commercializing the Fischer-Tropsch process. It covers recent developments related to renewable resources and green energy and provides a glimpse of the commercial potential of the Fischer-Tropsch process in synthetic fuel production.

Book Greener Fischer Tropsch Processes

Download or read book Greener Fischer Tropsch Processes written by Peter M. Maitlis and published by John Wiley & Sons. This book was released on 2013-01-30 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: Greener Fischer-Tropsch Processes How can we use our carbon-based resources in the most responsible manner? How can we most efficiently transform natural gas, coal, or biomass into diesel, jet fuel or gasoline to drive our machines? The Big Questions today are energy-related, and the Fischer-Tropsch process provides industrially tested solutions. This book offers a comprehensive and up-to-date overview of the Fischer-Tropsch process, from the basic science and engineering to commercial issues. It covers industrial, economic, environmental, and fundamental aspects, with a specific focus on “green” concepts such as sustainability, process improvement, waste-reduction, and environmental care. The result is a practical reference for researchers, engineers, and financial analysts working in the energy sector, who are interested in carbon conversion, fuel processing or synthetic fuel technologies. It is also an ideal introductory book on the Fischer-Tropsch process for graduate courses in chemistry and chemical engineering.

Book Mechanism and Kinetics of Fischer Tropsch Synthesis Over Supported Ruthenium Catalysts

Download or read book Mechanism and Kinetics of Fischer Tropsch Synthesis Over Supported Ruthenium Catalysts written by and published by . This book was released on 1981 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A detailed study of the kinetics of the Fischer-Tropsch synthesis of hydrocarbons, methanol, and acetaldehyde, over alumina- and silica-supported ruthenium catalysts has been carried out over a broad range of reaction conditions. Based on these results and information taken from the literature, mechanisms for the formation of normal paraffins, .cap alpha.-olefins, methanol, and acetaldehyde have been proposed. Rate data were obtained between 448 and 548K, 1 and 10 atm, and H2/CO ratios between 1 and 3, utilizing a micro flow reactor operated at very low conversions. In addition to the studies performed with H2/CO mixtures, a series of experiments were carried out utilizing D2/CO mixtures. These studies were used to help identify rate limited steps and steps that were at equilibrium. A complementary investigation, carried out by in situ infrared spectroscopy, was performed using a Fourier Transform spectrometer. The spectra obtained were used to identify the modes of CO adsorption, the CO coverage, and the relative reactivity of different forms of adsorbed CO. It was established that CO adsorbs on alumina-supported Ru in, at least, two forms: (i) Ru-CO and (ii) OC-Ru-CO. Only the first of these forms participates in CO hydrogenation. The coverage of this species is described by a simple Langmuir isotherm. A reaction mechanism is presented for interpreting the kinetics of hydrocarbon synthesis, the olefin to paraffin ratio for each product, and the probability of chain propagation. Rate expressions based on this mechanism are reasonably consistent with the experimental data. Acetaldehyde, obtained mainly over silica-supported Ru, appears to be formed by a mechanism related to that for hydroformulation of olefins. The effect of the dispersion of Ru/Al2O3 catalysts on their specific activity and selectivity was also investigated. The specific activity for all products decreased rapidly with increasing dispersions.

Book Ruthenium Based Fischer Tropsch Synthesis

Download or read book Ruthenium Based Fischer Tropsch Synthesis written by Cathrin Welker-Nieuwoudt and published by LAP Lambert Academic Publishing. This book was released on 2011-04 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Fischer-Tropsch (FT) synthesis is the catalytic conversion of hydrogen and carbon monoxide into higher hydrocarbons. Although ruthenium is the most active catalyst in FT synthesis, the lower cost metals iron and cobalt are used commercially. Generally, increased catalyst performance is achieved with increased metal surface area and dispersion, though recent literature reports that cobalt, iron and rhodium crystallites below a certain size in the nanometer range display lower metal surface area specific activity and a high methane selectivity. There have also been several attempts to investigate the possibility to conduct a homogeneously catalysed FT synthesis, which can be considered as an extreme case of metal dispersion. The aim of this study is to investigate FT activity and selectivity on well-defined nano-sized ruthenium crystallites and supported organometallic clusters with varying nuclearity, and to compare/bridge the obtained findings by subdividing it into a) catalyst preparation and characterisation, b) FT performance of model catalysts and c) theoretical investigations of the feasibility of FT reactions on ruthenium complexes.
