This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oxygen bonding strength, mobility and reactivity in nanocrystalline Ln-doped ceria-zirconia (Ln=La, Gd, Pr, Sm) with supported Pt, Ni, Ru were studied by state-of-the-art techniques such as isotopic exchange in static and flow reactors with 18O2 and C18O2, O2 TPD, H2 and CH4 TPR, pulse microcalorimetry and TAP reactor. Bulk oxygen mobility is found controlled by a rearrangement of Ce and Zr cations coordination sphere with doping as well as by fast oxygen migration along Pr3+/Pr4+ cationic chains. Surface and near-surface oxygen mobility appears controlled by a strong metal-support interaction with incorporation of metallic ions into surface layers and domain boundaries. In realistic feeds, the catalytic activity in dry reforming of methane correlates with oxygen mobility, required to prevent coking and metal sintering.Transient kinetic studies (non steady-state and SSITKA) allowed us to propose a bi-functional reaction mechanism corresponding to independent redox steps of CH4 and CO2 activation. The rate- limiting step is shown to be the irreversible activation of CH4 on metal sites, while CO2 dissociation on reduced sites of oxide supports proceeds much faster (being reversible for the steady-state surface) followed by a fast oxygen transfer along the surface/domain boundaries to metal sites where CH4 molecules are transformed to CO and H2. The CH4 selective conversion into syngas would involve strongly bound bridging oxygen species with heat of desorption ::600-650 kJ/mol O2. For optimized formulations, Ni+Ru clusters could be involved in CO2 activation via facilitating C-O bond breaking in the transition state, thus increasing the rate constant of the surface reoxidation by CO2, while strongly bound carbonates behave as spectators. For Pt/PrCeZrO, an additional fast route to syngas would occur on Pt ions with participation of weakly bound carbonates stabilized by neighboring Pr4+ ions. Such specificity makes this system highly promising for methane oxi-dry reforming, especially on structured corundum supports for short contact time compact reactors, well adapted to stranded and limited gas resources.

Download or read book SPONGE IRON PRODUCTION BY DIRECT REDUCTION OF IRON OXIDE written by AMIT CHATTERJEE and published by PHI Learning Pvt. Ltd.. This book was released on 2012-09-12 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a fascinating study of the very important emerging field of direct reduction in which iron ore is ‘directly reduced’ in the solid-state, using either natural gas or non-coking coal, to produce a highly metallised material, referred to as sponge iron (or direct reduced iron). This intermediate product is subsequently melted in electric arc furnaces or induction furnaces (sometimes even in basic oxygen furnaces) to produce liquid steel. Such a process combination enables steel to be produced without using coking coal, which is an expensive input in the normal blast furnace—basic oxygen furnace route of steelmaking adopted in integrated steel plants. The book offers comprehensive coverage and critical assessment of various coal-based and gas-based direct reduction processes. Besides dealing with the application of the theoretical principles involved in the thermodynamics and kinetics of direct reduction, the book also contains some worked-out examples on sponge iron production. The concluding part of this seminal book summarises the present and future scenario of direct reduction, including the use of gas generated from coal in direct reduction processes. The book is primarily intended for the undergraduate and postgraduate students of metallurgical engineering. It is also a must-read for researchers, technologists and process metallurgists engaged in the rapidly developing field of direct reduction of iron oxides, which is of critical importance for India and other developing nations that are beginning to play a major role in global steelmaking.

This book was released on 2012 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: Due to increasing atmospheric carbon dioxide (CO2) concentration, energy sources that release to the atmosphere smaller amounts of CO2 are of interest. Initially, all the efforts were focused on increasing the system efficiency, now more attention is being paid recently on capturing and sequestering CO2 from combustion process and eliminating discharge to the atmosphere from the major source points. In these circumstances, the chemical-looping combustion (CLC) is a promising concept that can be used in power generation which integrates power production and CO2 capture. The aim of this work is to study reaction kinetics of Chemical-Looping Combustion. In order to come up with a suitable reactor design we should have a good knowledge of the reaction kinetics happening in the air and fuel reactor; then, to get such an information as will be mentioned later, reactivity investigation was carried out in thermogravimetric analysis (TGA).

Available in PDF, EPUB and Kindle. Book excerpt: A reasonable case could be made that the scientific interest in catalytic oxidation was the basis for the recognition of the phenomenon of catalysis. Davy, in his attempt in 1817 to understand the science associated with the safety lamp he had invented a few years earlier, undertook a series of studies that led him to make the observation that a jet of gas, primarily methane, would cause a platinum wire to continue to glow even though the flame was extinguished and there was no visible flame. Dobereiner reported in 1823 the results of a similar investigation and observed that spongy platina would cause the ignition of a stream of hydrogen in air. Based on this observation Dobereiner invented the first lighter. His lighter employed hydrogen (generated from zinc and sulfuric acid) which passed over finely divided platinum and which ignited the gas. Thousands of these lighters were used over a number of years. Dobereiner refused to file a patent for his lighter, commenting that "I love science more than money." Davy thought the action of platinum was the result of heat while Dobereiner believed the ~ffect ~as a manifestation of electricity. Faraday became interested in the subject and published a paper on it in 1834; he concluded that the cause for this reaction was similar to other reactions.
