Available in PDF, EPUB and Kindle. Book excerpt: Introduction to Condensed Matter Chemistry offers a general view of chemistry from the perspective of condensed matter chemistry, analyzing and contrasting chemical reactions in a more realistic setting than traditional thinking. Readers will also find discussions on the goals and major scientific questions in condensed matter chemistry and the molecular engineering of functional condensed matter. Processes and products of chemical reactions should not be determined solely by the structure and composition of these basic species but also by the complex and possibly multilevel structured physical and chemical environment, together referred to as their condensed state. Relevant matters in condensed state should be the main bodies of chemical reactions, which is applicable not only to solids and liquids but also to gas molecules as reactions among gas molecules can take place only in the presence of catalysts in specific condensed states or after their state transition under extreme reaction conditions. This book provides new insights on the liquid state chemistry, definitions, aspects, and interactions, summarizing fundamentals of main chemical reactions from a new perspective. Helps to establish the new field of Condensed Matter Chemistry Highlights the molecular engineering of functional condensed matter Focuses on both liquid and solid state chemistry

Available in PDF, EPUB and Kindle. Book excerpt: Catalysis by solid acids, which includes (modified) zeolites, is of special relevance to energy applications. Acid catalysis is highly important in modern petroleum refining operations - large-scale processes such as fluid catalytic cracking, catalytic reforming, alkylation and olefin oligomerization rely on the transformation of hydrocarbons by acid catalysts. (Modified) zeolites are therefore essential for the improvement of existing processes and for technical innovations in the conversion of crude. There can be little doubt that zeolite-based catalysts will play a major role in the future management of fossil fuels and biomass, and this book is intended to contribute to tomorrow's achievements in this area.Each chapter presents the personal views of an expert, or a small group of experts, on the current state of the art, and on the trends in his/their field likely to lead to important developments. The presentation of these various keynotes in one volume will provide inspiration to the reader interested in the development of zeolite-based catalysts for energy applications, and in particular will suggest to the new-comer in the field of catalyst design, methods to develop his own original orientations.

This book was released on 2017-01-05 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis offers novel methods for catalyst and process design for the selective hydrogenation of acetylene and 1,3-butadiene. The author predicts the properties of supported Pd–Ni bimetallic catalysts using density functional theory (DFT) calculations and temperature-programmed desorption (TPD). The excellent correlation between model surfaces and supported catalysts demonstrates the feasibility of designing effective bimetallic catalysts for selective hydrogenation reactions. The author also proposes a method for designing non-precious metal catalysts to replace precious metals. She modifies the process of selective hydrogenation of acetylene by coupling the selective adsorption to the selective hydrogenation in the liquid phase, as a result of which the ethylene selectivity is greatly improved and heat transfer is greatly enhanced. Lastly, by analyzing the mechanism of liquid-phase hydrogenation, the author proposes a multi-stage slurry bed reactor for industrial applications.“/p>

This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The continued release of fossil-fuel derived carbon dioxide (CO2) emissions into our atmosphere led humanity into a climate and ecological crisis. Converting CO2 into valuable chemicals and fuels will replace and diminish the need for fossil fuel-derived products. Through the use of a catalyst, CO2 can be transformed into a commodity chemical by the reverse water gas shift (RWGS) reaction, where CO2 reacts with renewable hydrogen (H2) to form carbon monoxide (CO). CO then acts as the source molecule in the Fischer-Tropsch (FT) synthesis to form a range of hydrocarbons to manufacture chemicals and fuels. While the FT synthesis is a mature process, the conversion of CO2 into CO has yet to be made commercially available due to the constraints associated with high reaction temperature and catalytic stability. Noble metal ruthenium (Ru) has been widely used for the RWGS reaction due to its high catalytic activity, however, several constraints hinder its practical use, associated with its high cost and its susceptibility to deactivation. The doping or bimetallic use of non-noble metals iron (Fe) and cobalt (Co) is an attractive option to lower material cost and tailor the selectivity of the CO2 conversion towards the RWGS reaction without compromising catalytic activity. Furthermore, employing nanostructured catalysts as nanoparticles is a viable solution to further lower the amount of metal used and utilize the highly active surface area of the catalyst. Dispersing nanoparticles on ionically conductive supports/solid electrolytes which contain species like O2−, H+, Na+, and K+, provide an approach to further enhance the reaction. This phenomenon is referred to as metal-support interaction (MSI), allowing for the ions to back spillover from the support and onto the catalyst surface. An in-situ approach referred to as Non-Faradaic Modification of catalytic activity (NEMCA), also known as electrochemical promotion of catalysis (EPOC) is used to in-situ control the movement of ionic species from the solid electrolyte to and away from the catalyst. Both the MSI and EPOC phenomena have been shown to be functionally equivalent, meaning the ionic species act to alter the work function of the catalyst by forming an effective neutral double layer on the surface, which in turn alters the binding energy of the reactant and intermediate species to promote the reaction. The main objective of this work is to develop a catalyst that is highly active and selective to the RWGS reaction at low temperatures (

Available in PDF, EPUB and Kindle. Book excerpt: Comprehensive coverage on the growing science and technologyof producing ethanol from the world's abundant cellulosicbiomass The inevitable decline in petroleum reserves and its impact ongasoline prices, combined with climate change concerns, havecontributed to current interest in renewable fuels. Bioethanol isthe most successful renewable transport fuel—with corn andsugarcane ethanol currently in wide use as blend-in fuels in theUnited States, Brazil, and a few other countries. However, thereare a number of major drawbacks in these first-generation biofuels,such as their effect on food prices, net energy balance, and poorgreenhouse gas mitigation. Alternatively, cellulosic ethanol can beproduced from abundant lignocellulosic biomass forms such asagricultural or municipal wastes, forest residues, fast growingtrees, or grasses grown in marginal lands, and should be produciblein substantial amounts to meet growing global energy demand. The Handbook of Cellulosic Ethanol covers all aspects ofthis new and vital alternative fuel source, providing readers withthe background, scientific theory, and recent research progress inproducing cellulosic ethanol via different biochemical routes, aswell as future directions.
