Chemical Fixation of Carbon Dioxide presents new concepts and results from research into the problems caused by increasing levels of carbon dioxide. The book discusses the limitations of natural plant photosynthesis as a sink for carbon dioxide and emphasizes chemical fixation as an important alternative. A number of significant topics are covered, including new coupling reactions for producing compounds such as carbamates, urethanes, and heterocyclic structures; new catalyst systems, particularly for methanation and methanol synthesis; the use of homogeneous solution photosensitizers and heterogeneous semiconductor photocatalysts to photoreduce carbon dioxide with visible light and sunlight; and electrochemical reduction. This book will be a useful reference for organic chemists working on environmental problems, chemical engineers, environmental chemists, professionals at research facilities, and students.

PROMISING NEW APPROACHES TO RECYCLE CARBON DIOXIDE AND REDUCE EMISSIONS With this book as their guide, readers will learn a variety of new approaches and methods to recycle and reuse carbon dioxide (CO2) in order to produce green fuels and chemicals and, at the same time, minimize CO2 emissions. The authors demonstrate how to convert CO2 into a broad range of essential products by using alternative green energy sources, such as solar, wind, and hydro-power as well as sustainable energy sources. Readers will discover that CO2 can be a driving force for the sustainable future of both the chemical industry and the energy and fuels industry. Green Carbon Dioxide features a team of expert authors, offering perspectives on the latest breakthroughs in CO2 recycling from Asia, Europe, and North America. The book begins with an introduction to the production of CO2-based fuels and chemicals. Next, it covers such topics as: Transformation of CO2 to useable products through free-radical-induced reactions Hydrogenation of CO2 to liquid fuels Direct synthesis of organic carbonates from CO2 and alcohols using heterogeneous oxide catalysts Electrocatalytic reduction of CO2 in methanol medium Fuel production from photocatalytic reduction of CO2 with water using TiO2-based nanocomposites Use of CO2 in enhanced oil recovery and carbon capture and sequestration More than 1,000 references enable readers to explore individual topics in greater depth. Green Carbon Dioxide offers engineers, chemists, and managers in the chemical and energy and fuel industries a remarkable new perspective, demonstrating how CO2 can play a significant role in the development of a sustainable Earth.

This Annual Technical Progress Report presents the principle results in enhanced growth of algae using coal combustion products as a catalyst to increase bicarbonate levels in solution. A co-current reactor is present that increases the gas phase to bicarbonate transfer rate by a factor of five to nine. The bicarbonate concentration at a given pH is approximately double that obtained using a control column of similar construction. Algae growth experiments were performed under laboratory conditions to obtain baseline production rates and to perfect experimental methods. The final product of this initial phase in algae production is presented. Algal growth can be limited by several factors, including the level of bicarbonate available for photosynthesis, the pH of the growth solution, nutrient levels, and the size of the cell population, which determines the available space for additional growth. In order to supply additional CO2 to increase photosynthesis and algal biomass production, fly ash reactor has been demonstrated to increase the available CO2 in solution above the limits that are achievable with dissolved gas alone. The amount of dissolved CO2 can be used to control pH for optimum growth. Periodic harvesting of algae can be used to maintain algae in the exponential, rapid growth phase. An 800 liter scale up demonstrated that larger scale production is possible. The larger experiment demonstrated that indirect addition of CO2 is feasible and produces significantly less stress on the algal system. With better harvesting methods, nutrient management, and carbon dioxide management, an annual biomass harvest of about 9,000 metric tons per square kilometer (36 MT per acre) appears to be feasible. To sequester carbon, the algal biomass needs to be placed in a permanent location. If drying is undesirable, the biomass will eventually begin to aerobically decompose. It was demonstrated that algal biomass is a suitable feed to an anaerobic digester to produce methane. The remaining carbonaceous material is essentially bio-inactive and is permanently sequestered. The feasibility of using algae to convert carbon dioxide to a biomass has been demonstrated. This biomass provides a sustainable means to produce methane, ethanol, and/or bio diesel. The first application of concept demonstrated by the project could be to use algal biomass production to capture carbon dioxide associated with ethanol production.

This book provides an analysis of the reaction mechanisms relevant to a number of processes in which CO2 is converted into valuable products. Several different processes are considered that convert CO2 either in specialty chemicals or in bulk products or fuels. For each reaction, the mechanism is discussed and the assessed steps besides the dark sites of the reaction pathway are highlighted. From the insertion of CO2 into E-X bonds to the reduction of CO2 to CO or other C1 molecules or else to C2 or Cn molecules, the reactions are analysed in order to highlight the known and obscure reaction steps. Besides well known reaction mechanisms and energy profiles, several lesser known situations are discussed. Advancing knowledge of the latter would help to develop efficient routes for the conversion of CO2 into valuable products useful either in the chemical or in the energy industry. The content of this book is quite different from other books reporting the use of CO2. On account of its clear presentation, “Reaction Mechanisms in Carbon Dioxide Conversion” targets in particular researchers, teachers and PhD students.

Carbon Dioxide Utilisation: Closing the Carbon Cycle explores areas of application such as conversion to fuels, mineralization, conversion to polymers, and artificial photosynthesis as well as assesses the potential industrial suitability of the various processes. After an introduction to the thermodynamics, basic reactions, and physical chemistry of carbon dioxide, the book proceeds to examine current commercial and industrial processes, and the potential for carbon dioxide as a green and sustainable resource. While carbon dioxide is generally portrayed as a "bad" gas, a waste product, and a major contributor to global warming, a new branch of science is developing to convert this "bad" gas into useful products. This book explores the science behind converting CO2 into fuels for our cars and planes, and for use in plastics and foams for our homes and cars, pharmaceuticals, building materials, and many more useful products. Carbon dioxide utilization is a rapidly expanding area of research that holds a potential key to sustainable, petrochemical-free chemical production and energy integration. Accessible and balanced between chemistry, engineering, and industrial applications Informed by blue-sky thinking and realistic possibilities for future technology and applications Encompasses supply chain sustainability and economics, processes, and energy integration

Chemical engineering applications have been a source of challenging optimization problems in terms of economics and technology. The goal of this book is to enable the reader to get instant information on fundamentals and advancements in chemical engineering. This book addresses ongoing evolutions of chemical engineering and provides overview to the sate of the art advancements. Molecular perspective is increasingly important in the refinement of kinetic and thermodynamic molding. As a result, much of the material was revised on industrial problems and their sophisticated solutions from known scientists around the world. These issues were divided in to two sections, fundamental advances and catalysis and reaction engineering. A distinct feature of this text continues to be the emphasis on molecular chemistry, reaction engineering and modeling to achieve rational and robust industrial design. Our perspective is that this background must be made available to undergraduate, graduate and professionals in an integrated manner.
