Download or read book Microbial Transformations of Low Rank Coals written by Don L. Crawford and published by CRC Press. This book was released on 1992-09-24 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fifteen leading scientists active in research on the chemistry, microbiology, enzymology, and genetics of coal biotransformation summarize knowledge of the mechanisms by which bacteria and fungi metabolize the macromolecular structure of lignite coals. They also explore the potential for developing commercially viable biotransformations of low rank coals into useful chemicals and clean-burning liquid and gaseous fuels. Microbial Transformations of Low Rank Coals reviews the types of aerobic and anaerobic microbes known to transform fuel and discusses the relative potential of aerobic versus anaerobic organisms. Biochemical mechanisms used by microorganisms to solubilize, depolymerize, liquify, and gasify coal are examined. The book also reviews the potential for using microorganisms to remove organic sulfur from coal and the potential for using genetic engineering to improve coal biotransforming microorganisms.

Book excerpt: The objective of this project is to find biological methods to remove carboxylic functionalities from low rank coals under ambient conditions and to assess the properties of these modified coals towards coal decarboxylation. The microbial consortia will be developed using a fermentor system first under batch and then in a continuous system. The main objectives for this quarter were to develop microbial consortia that would decarboxylate coal and isolate potential anaerobic microorganisms with decarboxylating, ability from these enriched microbial consortia, to continue to compare the known cultures with reward to their ability to decarboxylate coal, and to characterize the anaerobically biotreated coal using FTIR to confirm decarboxylation of coal. Significant achievements during the period include: coal decarboxylation was possible only under anaerobic conditions. microbial consortia that can anaerobically decarboxylate coal have been developed using anaerobic vials and batch fermentor system, and loss of carboxyl groups in biotreated coal has been confirmed by FT-IR.

Download or read book Advanced Coal Preparation and Beyond written by S. Komar Kawatra and published by CRC Press. This book was released on 2020-01-27 with total page 572 pages. Available in PDF, EPUB and Kindle. Book excerpt: Updating content from the author’s 2001 book Coal Desulfurization, this new title focuses on CO2 sequestration and utilization. It includes information on the theory and practical approaches to CO2 capture and recent advances in the use of sequestered CO2. Avoiding these pollutants requires either forgetting about the 250 billion tons of coal reserves the United States possesses or capturing and utilizing the pollutants in a profitable and environmentally responsible fashion. The book covers postcombustion and precombustion capture approaches for coal, and postcombustion capture can be generalized to many other fuels. Recent practical implementations at full-scale power facilities around the world are discussed. The book covers sequestering CO2 via underground, oceanic, biological, and other long-term CO2 storage methods. It also includes recent advances in utilizing CO2 for enhanced oil recovery, advances in storage with depleted oil and gas reservoirs and deep saline aquifers, and additional topics. The book also examines specific applications of pure CO2 and covers chemical conversion of CO2 to useful compounds. It answers questions like "Can we create methanol from coal?" or "Can we create ethanol from coal?" It is found that methanol and ethanol cannot be sustainably produced from coal power alone. However, oxalic acid can be created at a much lower energy cost than methanol or ethanol. Oxalic acid can be used to extract rare earths, which are not currently produced anywhere in the United States, but are typically concentrated in coal ash. Aimed at researchers and industry professionals in chemical, environmental, and energy engineering, this book provides insight and inspiration into capturing CO2 not merely as a response to regulatory pressure and climate change but as an inherently profitable and valuable venture.

Download or read book Environmental Aspects of Trace Elements in Coal written by D.J. Swaine and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: Happy he who could learn the causes of things (Virgil, Georgics 11) There is clearly a place for a book on the environmental aspects of trace elements in coal, especially with the increasing use of coal for power production. Our aim is to provide relevant background information and to update the situation regarding trace elements during beneficiation, combustion, .atmospheric deposition, leaching from wastes anti reclamation. The outcome is a balanced account of the overall situation. The initial chapter gives the rationale behind the planning of the book and puts the topics into the context of trace elements in the environment, while the final chapter summarises the subject matter and conclusions of each chapter. The choice of authors was based on their specialised knowledge. Although every effort has been made to ensure uniformity in layout, use of units, references and the like, authors have been given some latitude in expression and their styles have not been curbed. This book is intended primarily for coal scientists and technologists involved in environmental aspects of trace elements during the mining of coal, its beneficiation and usage, especially for power generation, and for regulatory bodies. It is considered to be suitable for relevant postgraduate courses. Just as it has been said that one of Bruckner's symphonies has enough melodies for a Beethoven to have written ten symphonies, so this book has several chapters that could be themes for other books.

Available in PDF, EPUB and Kindle. Book excerpt: We are seeking to find biological methods to remove carboxylic functionalities from low-rank coals and to assess the properties of the modified coal towards coal liquefaction. The main objectives for this quarter were : continuation of microbial consortia development and maintenance, evaluation of commercial decarboxylase, decarboxylation of lignite, demineralized Wyodak coal and model polymer, and characterization of biotreated coals. Specifically we report that two batch fermentor systems were completed and three other fermentors under optimum conditions for coal decarboxylation are in progress; that inhibition of growth of methanogens in the batch fermentor system enhanced the carbon dioxide production; that adapted microbial consortium produced more gas from lignite than Wyodak subbituminous coal; that phenylalanine decarboxylase exhibited insignificant coal decarboxylation activity; that two different microbial consortia developed on coal seem to be effective in decarboxylation of a polymer containing free carboxylic groups; and that CHN analyses of additional biotreated coals reconfirm increase in H/C ratio by 3--6%.
Download or read book Coal Fired Power Generation Handbook written by James G. Speight and published by John Wiley & Sons. This book was released on 2021-02-17 with total page 784 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coal accounts for approximately one quarter of world energy consumption and of the coal produced worldwide approximately 65% is shipped to electricity producers and 33% to industrial consumers, with most of the remainder going to consumers in the residential and commercial sectors. The total share of total world energy consumption by coal is expected to increase to almost 30% in 2035. This book describes the challenges and steps by which electricity is produced form coal and deals with the challenges for removing the environmental objections to the use of coal in future power plants. New technologies are described that could virtually eliminate the sulfur, nitrogen, and mercury pollutants that are released when coal is burned for electricity generation. In addition, technologies for the capture greenhouse gases emitted from coal-fired power plants are described and the means of preventing such emissions from contributing to global warming concerns. Written by one of the world’s leading energy experts, this volume is a must-have for any engineer, scientist, or student working in this field, providing a valuable reference and guide in a quickly changing field.

Book excerpt: Research in the microbial desulfurization of coal has been underway for more than a decade. Certain microorganisms have the unique ability to modify coal or coal-derived substances. Some organisms can solubilize coal; others can attack the inorganic constitutents in coal; and others can degrade coal to more valuable products. Bioprocessing has potential for commercial applications that will help the electric utility industry with coal cleaning, upgrading, and waste cleanup. Ninety-eight coal scientists, microbiologists, engineers, and chemists representing utilities, universities, national laboratories, government agencies, and private companies met to discuss coal science, biological processing of coal, and remediation of coal-derived substances.
