Available in PDF, EPUB and Kindle. Book excerpt: to the Fundamental and Applied Catalysis Series Catalysis is important academically and industrially. It plays an essential role in the manufacture of a wide range of products, from gasoline and plastics to fertilizers and herbicides, which would otherwise be unobtainable or prohibitive ly expensive. There are few chemical-or oil-based material items in modern society that do not depend in some way on a catalytic stage in their manufacture. Apart from manufacturing processes, catalysis is finding other important and over-increasing uses; for example, successful applications of catalysis in the control ofpollution and its use in environmental control are certain to in crease in the future. The commercial import an ce of catalysis and the diverse intellectual challenges of catalytic phenomena have stimulated study by a broad spectrum of scientists including chemists, physicists, chemical engineers, and material scientists. Increasing research activity over the years has brought deeper levels of understanding, and these have been associated with a continually growing amount of published material. As recentlyas sixty years ago, Rideal and Taylor could still treat the subject comprehensively in a single volume, but by the 19 50s Emmett required six volumes, and no conventional multivolume text could now cover the whole of catalysis in any depth.

Book excerpt: Plasma catalysis is gaining increasing interest for various gas conversion applications, such as CO2 conversion into value-added chemicals and fuels, N2 fixation for the synthesis of NH3 or NOx, methane conversion into higher hydrocarbons or oxygenates. It is also widely used for air pollution control (e.g., VOC remediation). Plasma catalysis allows thermodynamically difficult reactions to proceed at ambient pressure and temperature, due to activation of the gas molecules by energetic electrons created in the plasma. However, plasma is very reactive but not selective, and thus a catalyst is needed to improve the selectivity. In spite of the growing interest in plasma catalysis, the underlying mechanisms of the (possible) synergy between plasma and catalyst are not yet fully understood. Indeed, plasma catalysis is quite complicated, as the plasma will affect the catalyst and vice versa. Moreover, due to the reactive plasma environment, the most suitable catalysts will probably be different from thermal catalysts. More research is needed to better understand the plasma–catalyst interactions, in order to further improve the applications.

Book excerpt: Since the turn of the last century when the field of catalysis was born, iron and cobalt have been key players in numerous catalysis processes. These metals, due to their ability to activate CO and CH, haev a major economic impact worldwide. Several industrial processes and synthetic routes use these metals: biomass-to-liquids (BTL), coal-to-liquids (CTL), natural gas-to-liquids (GTL), water-gas-shift, alcohol synthesis, alcohol steam reforming, polymerization processes, cross-coupling reactions, and photocatalyst activated reactions. A vast number of materials are produced from these processes, including oil, lubricants, waxes, diesel and jet fuels, hydrogen (e.g., fuel cell applications), gasoline, rubbers, plastics, alcohols, pharmaceuticals, agrochemicals, feed-stock chemicals, and other alternative materials. However, given the true complexities of the variables involved in these processes, many key mechanistic issues are still not fully defined or understood. This Special Issue of Catalysis will be a collaborative effort to combine current catalysis research on these metals from experimental and theoretical perspectives on both heterogeneous and homogeneous catalysts. We welcome contributions from the catalysis community on catalyst characterization, kinetics, reaction mechanism, reactor development, theoretical modeling, and surface science.

This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Catalytic CO2 hydrogenation for synthesis of methanol has attracted significant attention recently as a way of recycling carbon dioxide as a resource. In the past decades, most prior works focused on Cu-based and supported Pd-based catalysts to hydrogenate CO2 to CH3OH. Cu and Pd were proposed to have different affinities towards the adsorption of CO2 and H2, respectively. However, little attention has been paid to the effect of Pd-Cu bimetallic catalysts on the methanol synthesis from CO2 hydrogenation. Thus, this work aims at studying the effect of combining Pd and Cu on the activity and selectivity of methanol synthesis via CO2 hydrogenation and developing a fundamental understanding on composition-structure-activity relationship. The Pd-Cu bimetallic catalysts with various compositions were prepared and examined in CO2 hydrogenation at relatively mild reaction conditions (523 K and 4.1 MPa).A strong synergistic effect was observed over Pd--Cu bimetallic catalysts supported on silica at specific compositions as evidenced from the superior methanol formation rate and selectivity in comparison to monometallic catalysts, and the optimal Pd/(Pd+Cu) atomic ratios lied in the range of 0.25-0.34. The methanol formation rate over Pd(8.7)-Cu(10)/SiO2 was almost three times higher than the simple sum of those over monometallic Cu and Pd catalysts. To investigate the composition-structure-activity relationship, the Pd-Cu bimetallic catalysts were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning transmission electron microscopy coupled with energy dispersive X-ray spectroscopy (STEM/EDS), X-ray photoelectron spectroscopy (XPS), hydrogen temperature-programmed reduction (H2-TPR), and temperature-programmed desorption (H2-, CO2-, & CO-TPD). Detailed characterization results demonstrated the importance of two well-dispersed Pd--Cu alloy particles (PdCu3 and PdCu) for the observed methanol promotion over Pd--Cu bimetallic catalysts. DRIFTS spectra revealed that the incorporation of Pd and Cu greatly improved the formation of formate and CO species during the CO2 hydrogenation. CO-TPD profiles confirmed the existence of three forms of chemisorbed CO species, and the bonding strength increased in the following order: COL (linear)

Available in PDF, EPUB and Kindle. Book excerpt: The world is currently consuming about 85 million barrels of oil a day, and about two-thirds as much natural gas equivalent, both derived from non-renewable natural sources. In the foreseeable future, our energy needs will come from any available alternate source. Methanol is one such viable alternative, and also offers a convenient solution for efficient energy storage on a large scale. In this updated and enlarged edition, renowned chemists discuss in a clear and readily accessible manner the pros and cons of humankind's current main energy sources, while providing new ways to overcome obstacles. Following an introduction, the authors look at the interrelationship of fuels and energy, and at the extent of our non-renewable fossil fuels. They also discuss the hydrogen economy and its significant shortcomings. The main focus is on the conversion of CO2 from industrial as well as natural sources into liquid methanol and related DME, a diesel fuel substitute that can replace LNG and LPG. The book is rounded off with an optimistic look at future possibilities. A forward-looking and inspiring work that vividly illustrates potential solutions to our energy and environmental problems.

Book excerpt: The aim of this volume is to provide scientists with a comprehensive summary of new research areas in the activation of carbon monoxide, as one of the most reactive molecules, and in its applications. In order to understand the variety of the reactivity of CO, a quantum-chemical approach helps the reader to understand the binding state of CO to the solid surface (Chapter 1). The structure of the adsorbed CO can be better understood by examining its reactivity towards single crystals in the absence and in the presence of promoters (Chapter 2). The first approach in the reactivity study is that of studying catalytic activity of single crystals and structure sensitivity which are summarized in Chapter 3. One of the most prominent effects in the CO activation process is ascribed to the presence of additives, promoters which, in a real catalyst system, are far more complicated than on single crystal surfaces (Chapter 4). The original Fischer-Tropsch process applied fused iron or cobalt catalysts which were suitable for producing mainly straight chain hydrocarbons. The two most important processes involving CO activation, the new FT process and alcohol formation are discussed in Chapters 5 and 7. An important type of catalyst, the bimetallic catalysts, is discussed in Chapter 6. The role of hydrogen as one of the most frequently used partners in CO activation is discussed in Chapter 8. The field of production of specialty chemicals is an excellent example of the homogeneous catalytic activation of CO (Chapter 9). In Chapter 10 an overview is given of the industrial applications of CO chemistry and these are illustrated by working processes. The final chapter gives the reader some hints about future progress in the field.

This book was released on 2019-03-22 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydrogenation is a key reaction in both the food and petrochemical industries, where it is used to reduce carbon–carbon double bonds. Without a catalyst, hydrogenation reactions require extreme temperatures to occur, meaning catalysts are essential for the reaction to be industrially useful. During the past decade, the properties of many carbon nanomaterials that are relevant to hydrogenation catalysis have been described, including carbon nanotubes (CNTs), carbon nanofibers (CNFs), carbon nanohorns (CNHs), graphene oxide (GO), reduced graphene oxides (rGO) and fullerenes, that are relevant to hydrogenation catalysis, have been described. For many of these the production methods have advanced to the commercial stage. Numerous studies on the development of catalysts on carbon nano-supports have appeared in the scientific literature and these catalysts have shown remarkable activity and specificity. Carbon Nanomaterials in Hydrogenation Catalysis is a valuable reference for researchers and chemical engineers working on improving hydrogenation processes and those interested in applications for carbon nanomaterials. Covering their production, modification and applications as a catalyst support this book provides an in-depth review of the current state-of-the art in using carbon nanomaterials for hydrogenation reactions.
