Available in PDF, EPUB and Kindle. Book excerpt: The literature on the heterogeneous decomposition of hydrogen peroxide by inorganic catalysts was surveyed. The aim was to provide background information useful in the development of new catalysts for high-strength hydrogen peroxide in propulsion applications. The survey was prepared as part of a research program on the development of active, stable catalysts for decomposing 98 per cent hydrogen peroxide. Published literature, technical reports, and patents in the period 1945-1965 were included. The survey showed that silver and platinum are the most extensively investigated catalysts. Other major catalysts are palladium, copper, iron, cobalt, manganese, and their compounds. Various methods have been proposed for increasing catalytic activity by additives that promote the parent activity of elements or compounds. Samarium nitrate-treated silver, cobalt-manganese oxide mixtures, ruthenium and its compounds, and silver-gold alloys are the most active catalysts that have been reported.

Download or read book Controlling Non Catalytic Decomposition of High Concentration Hydrogen Peroxide written by and published by . This book was released on 2004 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydrogen peroxide (H2O2) is a strong oxidizing agent. High concentration H2O2 or High Test Peroxide (HTP) has been used extensively in the past in propulsion applications as mono and bipropellant. At low temperature, HTP can be catalytically decomposed to water and oxygen. Drawbacks to this approach include catalyst poisoning due to the presence of stabilizers in HTP, and susceptibility of the metal catalyst to melting because of the intense heat release. This renders the use of catalysts not only inconvenient but also quite expensive. An alternate approach for HTP decomposition is thermal, where no catalyst is required. HTP decomposition is accompanied by the production of enormous amount of heat that often leads to runaway reactions and subsequent explosion. If the rate of thermal decomposition can be controlled, the ensuing technology would prove to be a viable and inexpensive alternative to using catalysts. This technology has the potential to replace any device that decomposes H2O2 catalytically. Also, the controlled thermal decomposer can be used as an accelerator to heat any substance quickly at the expense of very low power. In order to control non-catalytic HTP decomposition, a deeper understanding of the chemical mechanism for H2O2 decomposition must be developed. The current work reports the development of detailed kinetic steps for HTP decomposition over a wide range of temperature and pressure. The resulting mechanism is then used to perform CFD simulations of a commercial HTP decomposer (patented by Pratt & Whitney) to explore safe operating conditions. A similar strategy can be applied to model COIL technology.

This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The widespread use of hydrogen peroxide (H2O2) for catalytic oxidations is limited by the wasteful process by which it is currently produced: the anthraquinone process. The direct synthesis of H2O2 (DSHP) is a promising alternative process. One primary technical obstacle to its commercialization is the identification of sufficiently active and selective heterogeneous catalysts. Although Pd is a promising active component that is used in most catalyst formulations, two factors have restricted the search directions for improved DSHP catalysts to experimental trial and error: (i) the reaction mechanisms are not resolved, and (ii) the active site requirements are poorly understood. Addressing these factors is complicated by the existence of multiple side reactions and the inherent complexities of heterogeneous catalysts and the DSHP reaction environment. In this dissertation, we employ density functional theory calculations to develop an atomic-scale understanding of the DSHP on Pd-based catalysts. We propose reaction mechanisms and analyze Pd's intrinsic reactivity toward forming H2O2 versus H2O from H2 and O2. We also develop an experimentally-consistent microkinetic model that describes H2O2 decomposition on Pd; one of the major drawbacks of Pd catalysts is high activity toward this undesirable reaction. Through these studies we highlight specific mechanistic challenges, including the identification of likely rate-limiting steps. We then consider how catalyst structure and composition can be modified to mitigate these challenges. We analyze the impact of the coordinative saturation of the Pd surface, the role of halides and Au as catalytic promoters, and the effect of phase transformations induced by the reaction environment. Our work demonstrates the utility of computational chemistry in deconvoluting complex catalytic systems - especially when coupled with experimental and microkinetic analyses. The results can potentially be used to build a framework that guides the search for new DSHP catalysts.
Download or read book Catalytic Oxidations with Hydrogen Peroxide as Oxidant written by G. Strukul and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydrogen peroxide is a chemical that is becoming increasingly fashionable as an oxidant, both in industry and in academia and whose production is expected to increase significantly in the next few years. This growth in interest is largely due to environmental considerations related to the clean nature of hydrogen peroxide as an oxidant, its by-product being only water. To date this chemical has largely been employed as a non-selective oxidant in operations like the bleaching of paper, cellulose and textiles, or in the formulation of detergents, and only to a minimal extent in the manufacture of organic chemicals. This book has been organized to cover the different aspects of the chemistry of hydrogen peroxide. The various chapters into which the book is divided have been written critically by the authors with the general aim of stimulating new ideas and emphasizing those aspects that are likely to lead to new developments in organic synthesis in the coming future.
