Book excerpt: Depletion in the reserves of fossil fuels, inefficient energy production from these fuels and the negative effect of their usage on atmosphere, and thereby, on human health have accelerated researches on clean energy. Hydrogen produced from ethanol when used in fuel cells not only generates efficient energy but also creates a closed carbon cycle in nature. ZnO and Cu/ZnO catalysts are known with their superior performance in alcohol synthesis. From the principle of microkinetic reversibility they are expected to be superior catalysts for the steam reforming reaction of ethanol as well. ZnO catalysts can be modified by precious, Pd, or non-precious, Cu, metals to enhance hydrogen desorption capability, and dispersed on SiO2 for high surface areas via sol-gel technique. Steam reforming tests over ZnO catalysts revealed that they act only as ethanol dehydrogenation catalysts in the temperature range of 300-500C. Promotion with Pd or Cu decreased hydrogen selectivity due most probably to unreachable closed pores of the catalysts. Autothermal reforming tests over both ZnO/SiO2 and Co/SBA-15 catalysts, on the other hand, gave rise to the formation of several side products.

This book was released on 2023-01-30 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses the synthesis of catalytic materials with improved and tailored functionalities via the sol-gel method. Beginning with a general outline of traditional sol-gel chemistry, the book gradually explores surrounding topics, such as the formation of porous structures, while guiding the overall discussion toward the synthesis of heterogeneous catalysts and focusing throughout on the structure-activity relationship in catalytic materials. Featuring several case studies covering major current industrial applications, the book is an ideal guide for researchers looking to tailor catalytic materials for a specific catalytic process and thus exploiting the versatility of the “traditional” sol-gel method.

This book was released on 2006 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: The majority of current energy needs are supplied by combustion of nonrenewable energy sources such as fossil fuels, which is associated with release of large quantities of greenhouse gases, especially carbon dioxide and other harmful emissions to the atmosphere. The gradual depletion of these fossil fuels reserves and efforts to combat pollution and greenhouse gas emissions have generated a considerable interest in using alternative sources of energy. Ethanol used in the hydrogen production process by steam reforming. The purpose of this work was to design a high performance catalyst for the production of hydrogen from steam reforming of ethanol. Ethanol steam reforming reaction is an endothermic reaction of ethanol with water to produce hydrogen and carbon dioxide. The different ZnO loading supported SiO2 catalyst and Cu promoted ZnO/SiO2 catalysts were prepared single step sol-gel method with different Cu loading. All catalysts were characterized by X-ray diffraction, BET surface area measurements and pore diameter analysis. BET surface area decreased and average pore diameter increased as the ZnO loading increased. Based on the XRD findings, it seems that zinc silicate crystallite phase is not formed under the preparation conditions used in this dissertation. The activity and selectivity tests of all catalysts were performed in a packed bed reactor with reaction temperature between 300 and 500oC. The performances of ZnO/SiO2 catalysts in ethanol steam reforming reaction were investigated as a function of ZnO loading. Cu catalysts are known as active catalysts for ethanol dehydrogenation. As the temperature was increased, the conversion increased and reached a maximum at 500oC for all Cu loadings.

Available in PDF, EPUB and Kindle. Book excerpt: Industrial Arene Chemistry Explore the wide array of uses for aromatic hydrocarbons in this comprehensive reference Aromatics are a class of compounds—normally but not exclusively organic—which tend to be produced as by-products of various industrial processes. Their importance as petrochemical materials in themselves, along with the range of inter-relations between different aromatic chemicals, creates a complex and opportunity-filled market for aromatics. Industrial Arene Chemistry provides a thorough look at the conventional techniques required to use and produce these aromatic hydrocarbons. Beginning with an overview of the global aromatic market—including, but not limited to, manufacturers, markets of BTX, and downstream functional aromatics, aromatics derived from renewable sources, and economic forecasts—the book will also explore the impact shifting environmental factors will have on the future of aromatic chemistry. The text further explores BTX production processes differentiated according to the raw materials used. Importantly, this will establish the importance and growth of the biobased chemical industry. Industrial Arene Chemistry readers will also find: Case studies that describe major elements of specific technologies prototyped by contributors/companies as part of ongoing market development efforts Process chapters that include summaries of the conventional techniques and a more detailed discussion of recent high-impact studies Recent advances in conventional aromatic reactions, including alkylation, acylation and carboxylation, hydrogenation/reduction, oxidation, nitration/amination, sulfonation, and halogenation Industrial Arene Chemistry is a useful reference for chemists and chemical engineers who work with aromatics.

This book was released on 2008 with total page 269 pages. Available in PDF, EPUB and Kindle. Book excerpt: The conversion of ethanol to hydrogen or syngas can be achieved by reacting ethanol with water via steam reforming, CH3CH2OH + (1-x)H2O = (4-x)H2 + (2-x)CO + xCO2 (R.1) CH3CH2OH + H2O = 4H2 + 2CO (R.2) CO + H2O = H2 + CO2 (R.3) Ideally, the ethanol steam reforming reaction can achieve a hydrogen yield of 6 moles of hydrogen per mole of ethanol when the value of x in (R.1) equals 2. High theoretical H2 yield makes ethanol steam reforming a very attractive route for H2 production. Thermodynamic equilibrium studies have shown that ethanol steam reforming produces mixtures of H2, CO, CO2, and CH4 below 950 K, while above 950 K the ethanol steam reforming reaction (R.1) adequately describes the product composition In this study a series of 10wt% Ni loaded Mg-Al mixed oxide supported catalysts were evaluated for the production of hydrogen via the steam reforming of ethanol.

Book excerpt: This most comprehensive and unrivaled compendium in the field provides an up-to-date account of the chemistry of solids, nanoparticles and hybrid materials. Following a valuable introductory chapter reviewing important synthesis techniques, the handbook presents a series of contributions by about 150 international leading experts -- the "Who's Who" of solid state science. Clearly structured, in six volumes it collates the knowledge available on solid state chemistry, starting from the synthesis, and modern methods of structure determination. Understanding and measuring the physical properties of bulk solids and the theoretical basis of modern computational treatments of solids are given ample space, as are such modern trends as nanoparticles, surface properties and heterogeneous catalysis. Emphasis is placed throughout not only on the design and structure of solids but also on practical applications of these novel materials in real chemical situations.
