Download or read book Natural Gas Conversion IV written by M. de Pontes and published by Elsevier. This book was released on 1997-03-14 with total page 601 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Fourth International Natural Gas Conversion Symposium was attended by 180 delegates from 25 countries. Representation was evenly balanced between industry and academia. The opening address was delivered by Mr Roy Pithey, Chairman of South Africa's Central Energy Fund, who dealt with the importance and utilisation of natural gas in sub-Saharan Africa. Plenary lectures were presented by Professors E. Iglesia (Catalyst design and selectivity for F-T synthesis) and E.E. Wolf (Oxidative Coupling Methane). A number of keynote addresses were delivered: - Dr T. Fleisch (Amoco) described the use of DME as a transport fuel and the work which has been carried out in this area in collaboration with Haldor Topsoe - Professor L.D. Schmidt (Univ. of Minnesota) explained his work on the direct conversion of methane at high velocities - Dr B. Jager (SASTECH R & D) reported on the recent developments in slurry and fluidized bed F-T reactors as SASOL - Dr J. Rostrup-Nielsen (Haldor Topsoe) discussed the role of catalysis in the conversion of natural gas for power generation. Areas signalled for further research were: direct conversion of methane to intermediate monomers; methanol conversion to higher alcohols; CO/H2 conversion in a commercially viable route to higher alcohols; and CO/H2 conversion to high quality gasoline. It is obvious that such developments would fit into the energy cycle which has moved from wood, to coal, to oil, to gas, and will most probably move to hydrogen.

Download or read book Effect of Alumina Support Modification on Performance of Cobalt and Iron Catalysts in Fischer-tropsch Reaction written by and published by . This book was released on 2006 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: Effect of alumina support modification for applications as cobalt and iron catalyst supports in Fischer-Tropsch reaction were studied. Alumina supports consisting of various gamma to chi ratios were prepared using solvothermal method and employed as supports for cobalt catalysts. In order to identify the characteristics, all the catalysts were characterized using surface area analysis, X-ray diffraction (XRD), Scanning electron microscopy2Energy dispersive X-ray (SEM/EDX), Transmission electron microscopy (TEM), Fourier transform Infrared Spectroscopy (FT-IR), Temperature programmed reduction (TPR), and hydrogen and carbon monoxide chemisorption. CO hydrogenation (H 2CO = 10/1) was also performed to determine the overall activity and selectivity of the Co/AL O catalysts containing various gamma to chi ratios. It was found that both activity and selectivity were increased with increasing the chi to gamma ratios of the alumina supports. It is suggested that the spherical;-shape like morphology of the -phase AL O provide better stability and dispersion of the Co particles. In addition, the effect of Cu-modification of alumina support for applications as iron catalyst supports in Fischer-Tropsch reaction (H 2CO - 2/1) was also investigated. It was found that the use of copper-modified alumina supports enhanced both reducibilities and the overall activities of Fe/AL O catalysts. However, Cu-modification of alumina support appeared to have no effect on selectivity of the F-T products.

Available in PDF, EPUB and Kindle. Book excerpt: Currently, cobalt and related catalysts are very attractive as they provide many advantages, such as low cost and high activity, in a variety of applications. Cobalt catalysts are among the most active catalysts for Fischer-Tropsch synthesis and they promote the catalytic activity of the hydrodesulfurization catalysts. They also found other significant applications in environmental protection such as oxidation of volatile organic compounds, VOC, persulfate activator, ammonia synthesis, electrocatalysis and many more. Cobalt catalysts are active, stable and exhibit significant oxidation-reduction activity, as the Co can be found either as Co(II) or Co(III). Additionally, many molecules can interact with the cobalt supported phase by co-ordination due to partially filled d-orbital. Co-catalysts can be supported in almost all the inorganic supports such as alumina, titania, zeolites, etc. The cobalt oxide phase can be stabilized on the surface of the support due to variable interactions between the support and cobalt phase. These interactions are crucial for catalytic activity and can be regulated by proper selection of the preparation parameters such as the type of support, the Co loading, impregnation method and thermal conditions.

This book was released on 2007-10-31 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: The need to improve both the efficiency and environmental acceptability of industrial processes is driving the development of heterogeneous catalysts across the chemical industry, including commodity, specialty and fine chemicals and in pharmaceuticals and agrochemicals. Drawing on international research, Supported Catalysts and their Applications discusses aspects of the design, synthesis and application of solid supported reagents and catalysts, including supported reagents for multi-step organic synthesis; selectivity in oxidation catalysis; mesoporous molecular sieve catalysts; and the use of Zeolite Beta in organic reactions. In addition, the two discrete areas of heterogeneous catalysis (inorganic oxide materials and polymer-based catalysts) that were developing in parallel are now shown to be converging, which will be of great benefit to the whole field. Providing a snapshot of the state-of-the-art in this fast-moving field, this book will be welcomed by industrialists and researchers, particularly in the agrochemicals and pharmaceuticals industries.
