Download or read book Reaction Mechanisms in Carbon Dioxide Conversion written by Michele Aresta and published by Springer. This book was released on 2015-11-07 with total page 423 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book CHEMICAL FIXATION OF CO2 IN COAL COMBUSTION PRODUCTS AND RECYCLING THROUGH BIOSYSTEMS written by C. Henry Copeland and published by . This book was released on 2003 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 was released on 2012-08-11 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this volume, Professor He and his coworkers summarize polyethylene glycol (PEG)-promoted CO2 chemistry on the basis of understanding about phase behavior of PEG/CO2 system and reaction mechanism at molecular level. As PEG could be utilized as a green replacement for organic solvents, phase-transfer catalyst, surfactant, support in various reaction systems, significantly promoting catalytic activity and recovering expensive metal catalysts, particularly regarded as a CO2-philic material, the authors focus on special applications of PEG in CO2 capture and utilization, including PEG-functionalized catalysts for efficient transformation of CO2 and PEG-functionalized absorbents for efficient CO2 capture. Furthermore, they describe carbon capture and utilization strategy as an alternative approach to address the energy penalty problem in carbon capture and storage. Interestingly, the authors also discuss PEG radical chemistry in dense CO2 as rather creative and unusual use of PEG, presumably serves as a reaction medium and a radical initiator for radical chemistry.

Download or read book Advances in Carbon Capture and Utilization written by Deepak Pant and published by Springer Nature. This book was released on 2021-07-26 with total page 331 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the recent trends in carbon management and up-to-date information on different carbon management strategies that lead to manage increasing concentration of atmospheric carbon dioxide. The growing evidence of climate change resulting from the continued increase of atmospheric carbon dioxide concentration has made it a high profile political–social and trade issue. The mean global average earth temperature rose by 0.6± 2°C during the second half of the century with the rate of 0.17°C/decade. As per GISS data in the year of 2017, it rose 0.9°C (1.62 °F) above the 1951-1980 mean global temperature. Recently World Meteorological Organization analyzes the past record temperature and found the past 10 years were the warmest years about 1.1°C above preindustrial level. Over the past decade, carbon management by various techniques has to come to fore as a way to manage carbon dioxide emissions contributing to climate change. The proposed book addresses the need for an understanding of sustainable carbon dioxide management technologies mainly focused on (a) minimizing carbon dioxide emission from sources; (b) maximizing environmentally sound recuse, reduce and recycling; (c)emerging technology toward carbon dioxide mitigation and d) converting carbon dioxide into valuable products form sustainable use. Other books related to carbon management attempt to cover the carbon capture and sequestration, carbon mineralization, utilization and storage but the topic of CO2 management strategies is not discussed in detail for sustainable development. Furthermore, this book also covers all physical, chemical and biological process for long-term capture, removal and sequestration of carbon dioxide from the atmosphere for sustainable management which is not described in other carbon management books. In order to meet CO2 emissions reduction target, a range of technological approaches, including development of clean fuels and clean coal technologies, adopting cleaner and more energy efficiency and conservation, developing renewable energy and implementing CCS technologies, will also be considered for sustainable future.

Download or read book Design and Construction of a Synthetic CO2 Fixation Cycle in Vitro written by Shanshan Luo and published by . This book was released on 2018 with total page 125 pages. Available in PDF, EPUB and Kindle. Book excerpt: The increasing atmospheric carbon dioxide (CO2) level is calling for more efficient CO2 fixation systems to re-balance the carbon cycle. At the same time, atmospheric CO2 can in principle be a cheap and abundant carbon source for synthesizing various organic compounds. Converting CO2 into useful chemicals can be an ideal solution for a sustainable future. However, due to its high thermodynamic stability and kinetic inertness, the chemical transformation of CO2 into organic compounds usually requires quite harsh conditions. In contrast, nature has evolved several CO2 fixation pathways for synthesizing longer carbon chain compounds from CO2 under ambient conditions. To date, six CO2 fixation pathways have been reported. However, they all contain key carboxylases with intrinsic properties such as structural complexity and oxygen sensitivity that hinder their further engineering and applications. To circumvent these problems, we designed a synthetic CO2 fixation cycle composed of all efficient, simple and oxygen tolerant enzymes and demonstrated its function in vitro. In this work, we utilized the two most active and oxygen-insensitive carboxylases, crotonyl-CoA carboxylase/reductase (Ccr) and phosphoenolpyruvate carboxylase (Ppc) to fix CO2 and bicarbonate, respectively. Our designed cycle is composed of the reductive glyoxylate synthesis (rGS) pathway and the reductive pyruvate synthesis (rPS) pathway. The rGS pathway converts one pyruvate to one glyoxylate and one acetyl-CoA fixing one bicarbonate, while the rPS pathway converts one acetyl-CoA to pyruvate with one CO2 fixed. Together, we obtained a CO2 fixation cycle termed the reductive glyoxylate/pyruvate synthesis (rGPS) cycle. We first validated the feasibility of rGPS with its stepwise reconstitution in vitro. Using a two-pot immobilized enzyme system, we were able to run the rGPS cycle semi-continuously. To further improve its efficiency, we developed electrochemical and enzymatic FAD regeneration systems to run the rGPS cycle continuously in one pot. Using the enzymatic FAD regeneration method increased the CO2 fixation rate of rGPS to 66.9 nmol min-1 mg-1 of core cycle proteins. We further explored the construction of rGPS in vivo. The rGS part has been demonstrated in vivo. The rPS part has not worked in E. coli for growth rescue, although all ten enzymes of rPS were confirmed to be active in crude extract assays. Finally, strategies for constructing a fully functional rGPS in vivo have been proposed.
