Continuous Process for Oxidative Conversion of Methane to Higher Hydrocarbons in the Gas Phase

Book Description
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.

The Gas-Phase Oxidation of Hydrocarbons
Author: V. Ya. ShternPublisher: Elsevier
ISBN: 1483185079
Category : Science
Languages : en
Pages : 721
Book Description
The Gas-Phase Oxidation of Hydrocarbons reviews research on the mechanism of oxidation of paraffins, naphthenes, olefines, and aromatic hydrocarbons and explains in detail the phenomena and theories with significant kinetic equations and graphs. This book first presents a study of the development of research on the gaseous-phase oxidation of hydrocarbons. The non-chain schemes for the oxidation of hydrocarbons, such as hydroxylation, peroxidation, and aldehyde and dehydrogenation schemes, are then discussed. This book also presents experimental investigations and important topics such as oxidation of methane and olefinic hydrocarbons. This selection will be invaluable to students and experts in the field of chemistry and related disciplines.
Mechanism-Imposed Limitations on the Yield of Higher Hydrocarbons from the Oxidative Coupling of Methane, and Alternate Approaches to Methane Conversion

Languages : en
Pages : 12
Book Description
The conversion of methane to higher hydrocarbons via oxidative coupling over metal oxide catalysts is the subject of intense study as a route for natural gas upgrading. Detailed study on the reaction of methane over a mixed manganese-magnesium oxide implicates a mechanism involving generation of methyl radicals at the surface, followed by radical coupling as well as other radical reactions in the gas phase as the predominant mode of carbon-carbon bond formation. Analysis of the consequences of this mechanisms suggests that there is an inherent limit on yield, including a major adverse pressure effect, that may severely impact the potential utility of this route. Among several possible approaches to circumventing this limitation, a novel class of catalyst - transition metal-exchanged P -alumina -- has been found to be highly active for complete oxidation of methane. Results of catalytic and characterization studies will be presented.
Catalysis

Category : Catalysis
Languages : en
Pages : 376
Book Description
Catalysts are required for a variety of applications and researchers are increasingly challenged to find cost effective and environmentally benign catalysts to use. This volume looks at modern approaches to catalysis and reviews the extensive literature including direct methane conversion, nanocomposite catalysts for transformation of biofuels into syngas and hydrogen, and catalytic wet air oxidation technology for industrial wastewater treatment. Appealing broadly to researchers in academia and industry, it will be of great benefit to any researcher wanting a succinct reference on developments in this area now and looking to the future.
Catalytic Partial Oxidation of Methane at High Flowrates

Author: D.M. BibbyPublisher: Elsevier
ISBN: 0080960707
Category : Technology & Engineering
Languages : en
Pages : 759
Book Description
This proceedings volume comprises the invited plenary lectures, contributed and poster papers presented at a symposium organised to mark the successful inauguration of the world's first commercial plant for production of gasoline from natural gas, based on the Mobil methanol-to-gasoline process. The objectives of the Symposium were to present both fundamental research and engineering aspects of the development and commercialization of gas-to-gasoline processes. These include steam reforming, methanol synthesis and methanol-to-gasoline. Possible alternative processes e.g. MOGD, Fischer-Tropsch synthesis of hydrocarbons, and the direct conversion of methane to higher hydrocarbons were also considered.The papers in this volume provide a valuable and extremely wide-ranging overview of current research into the various options for natural gas conversion, giving a detailed description of the gas-to-gasoline process and plant. Together, they represent a unique combination of fundamental surface chemistry catalyst characterization, reaction chemistry and engineering scale-up and commercialization.
Cleaner Combustion
Author: Frédérique Battin-LeclercPublisher: Springer Science & Business Media
ISBN: 1447153073
Category : Technology & Engineering
Languages : en
Pages : 657
Book Description
This overview compiles the on-going research in Europe to enlarge and deepen the understanding of the reaction mechanisms and pathways associated with the combustion of an increased range of fuels. Focus is given to the formation of a large number of hazardous minor pollutants and the inability of current combustion models to predict the formation of minor products such as alkenes, dienes, aromatics, aldehydes and soot nano-particles which have a deleterious impact on both the environment and on human health. Cleaner Combustion describes, at a fundamental level, the reactive chemistry of minor pollutants within extensively validated detailed mechanisms for traditional fuels, but also innovative surrogates, describing the complex chemistry of new environmentally important bio-fuels. Divided into five sections, a broad yet detailed coverage of related research is provided. Beginning with the development of detailed kinetic mechanisms, chapters go on to explore techniques to obtain reliable experimental data, soot and polycyclic aromatic hydrocarbons, mechanism reduction and uncertainty analysis, and elementary reactions. This comprehensive coverage of current research provides a solid foundation for researchers, managers, policy makers and industry operators working in or developing this innovative and globally relevant field.
