This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Light olefins like ethylene and propylene are important building blocks for the chemical industry. Production of these chemicals exceeds 100 million metric tons each year, and they are used in all areas of society including automotive, medical, textile, and food packaging. These light olefins are traditionally produced via steam cracking which is an energy intensive process. The increasing availability of natural gas in the present chemical industry has shifted the feedstock for refinery processes and impacted the production volume of certain olefins, particularly propylene. As a result, there is a growing need for on-purpose propylene production methods to meet the market demands. Oxidative dehydrogenation (ODH) of propane to propylene is one potential pathway for increasing propylene production. Propane ODH offers lower temperature operation and does not suffer from catalyst deactivation from coke. This process still suffers from over oxidation of products and does not achieve propylene yields required for industrial implementation. Propane ODH has been studied extensively for vanadium oxide catalysts and more recently for boron-based catalysts. Despite the wealth of literature on these ODH catalyst there are still several open questions on the catalyst structure and reaction mechanisms that continue to motivate research to improve the catalytic systems. The understanding on the mechanism and structural features of boron-based has been significantly developed in recent years. This work serves to build on this knowledge and improve current knowledge on structure activity relationships for this system. Vanadium oxide catalysts have been the center of propane ODH for much longer than boron, and while literature agrees generally on the surface mechanism description of this system, there are open questions on different pathways in the mechanism and their influence on performance. The goal of this work is to show how synthesis spectroscopy, reaction engineering, and computation work combine to further the understanding of boron and vanadium oxide catalyst for propane ODH.

Tarlton and published by . This book was released on 2014 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: A series of vanadium(IV) dimers have been synthesized that bear bridging phosph(on/in)ate ligands with varying substituents, and terminal methoxy and ethoxy KlaA¼i ligands [CpPOR,ORCo] --, R=Me, Et, resulting in two VO6 centers per complex. The complexes have been widely characterized, employing techniques such as spectroscopy, X-ray diffraction, and electrochemical analysis. The oxidative catalytic activity of each complex on the oxidation of 3,5-di-tert -butylcatechol to 3,5-di-tert-butyl-o-benzoquinone under aerobic conditions is presented herein.
Download or read book Gaseous Vanadium Vanadium Oxide and Hydroxide Clusters written by Sandra Feyel and published by Logos Verlag Berlin GmbH. This book was released on 2008 with total page 211 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present work explores the reactivities of gaseous vanadium, vanadium-oxide, and oxovanadium-hydroxide clusters toward methanol and small hydrocarbons. Various means of mass-spectrometric techniques, isotopic labeling studies, infrared photodissociation spectroscopy, and complementary DFT-calculations are employed for this purpose. Additionally, the hydrogen-atom abstraction process from methane by polynuclear metal oxides is discussed. This work contributes to a better understanding of the metal-oxide cluster's catalytic activity on a molecular scale.

Available in PDF, EPUB and Kindle. Book excerpt: Vanadium is one of the more abundant elements in the Earth’s crust and exhibits a wide range of oxidation states in its compounds making it potentially a more sustainable and more economical choice as a catalyst than the noble metals. A wide variety of reactions have been found to be catalysed by homogeneous, supported and heterogeneous vanadium complexes and the number of applications is growing fast. Bringing together the research on the catalytic uses of this element into one essential resource, including theoretical perspectives on proposed mechanisms for vanadium catalysis and an overview of its relevance in biological processes, this book is a useful reference for industrial and academic chemists alike.
