Book excerpt: This research is sponsored by the Wyoming Carbon Engineering Initiative, a state fundedprogram that seeks to convert Wyoming subbituminous coal into primarily non-fuel higher valuedproducts to revitalize Wyoming’s economy. One focus of this initiative is a proposed continuouscoal extraction pilot plant that will produce cleaner, ash free coal by solvent extraction, a coal toliquids conversion process where the organic matter in coal is dissolved in an organic solvent. This study examined the feasibility of possible post-extraction separation techniques ofcoal in solvent for the proposed pilot plant. Filtration of coal extract in tetralin was analyzed torecommend the filter size for the pilot plant. Bench top toluene and cyclohexane recrystallizationexperiments were performed to examine the effects of solvent and recrystallization temperature onthe split between the soluble and insoluble fraction during extract recrystallization. Tetralin was initially identified as the solvent of choice for the pilot plant. Though it is anexcellent hydrogen donating solvent, tetralin is expensive and presents possible health hazards infinal products. Alternative extraction solvents were examined in this study. Ampoules of coal andvarious solvents were tested at 200, 250, 300, and 350°C using a Teflon lined hydrothermalautoclave and high-pressure stainless-steel tube reactors. The results suggested that phenol andethylene glycol are potential alternative solvents. It was also concluded that treating the coalsample with acid prior to extraction increased the effectiveness of solvent extraction with phenoland tetralin. A variety of analytical methods was used to characterize extracted products.

This book was released on 2002-03-14 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Office of Industrial Technologies (OIT) of the U. S. Department of Energy commissioned the National Research Council (NRC) to undertake a study on required technologies for the Mining Industries of the Future Program to complement information provided to the program by the National Mining Association. Subsequently, the National Institute for Occupational Safety and Health also became a sponsor of this study, and the Statement of Task was expanded to include health and safety. The overall objectives of this study are: (a) to review available information on the U.S. mining industry; (b) to identify critical research and development needs related to the exploration, mining, and processing of coal, minerals, and metals; and (c) to examine the federal contribution to research and development in mining processes.

Download or read book Green Techniques for Organic Synthesis and Medicinal Chemistry written by Wei Zhang and published by John Wiley & Sons. This book was released on 2018-01-18 with total page 1127 pages. Available in PDF, EPUB and Kindle. Book excerpt: An updated overview of the rapidly developing field of green techniques for organic synthesis and medicinal chemistry Green chemistry remains a high priority in modern organic synthesis and pharmaceutical R&D, with important environmental and economic implications. This book presents comprehensive coverage of green chemistry techniques for organic and medicinal chemistry applications, summarizing the available new technologies, analyzing each technique’s features and green chemistry characteristics, and providing examples to demonstrate applications for green organic synthesis and medicinal chemistry. The extensively revised edition of Green Techniques for Organic Synthesis and Medicinal Chemistry includes 7 entirely new chapters on topics including green chemistry and innovation, green chemistry metrics, green chemistry and biological drugs, and the business case for green chemistry in the generic pharmaceutical industry. It is divided into 4 parts. The first part introduces readers to the concepts of green chemistry and green engineering, global environmental regulations, green analytical chemistry, green solvents, and green chemistry metrics. The other three sections cover green catalysis, green synthetic techniques, and green techniques and strategies in the pharmaceutical industry. Includes more than 30% new and updated material—plus seven brand new chapters Edited by highly regarded experts in the field (Berkeley Cue is one of the fathers of Green Chemistry in Pharma) with backgrounds in academia and industry Brings together a team of international authors from academia, industry, government agencies, and consultancies (including John Warner, one of the founders of the field of Green Chemistry) Green Techniques for Organic Synthesis and Medicinal Chemistry, Second Edition is an essential resource on green chemistry technologies for academic researchers, R&D professionals, and students working in organic chemistry and medicinal chemistry.

Book Synopsis Extraction of Natural Products Using Near-Critical Solvents by : M.B. King
Download or read book Extraction of Natural Products Using Near-Critical Solvents written by M.B. King and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this book is to present the current state of the art of extracting natural products with near-critical solvents and to view the possibilities of further extensions of the technique. Relevant background theory is given but does not dominate the book. Carbon dioxide is the near-critical solvent used in most recent applications and inevitably receives prominence. In addition to general descriptions and reviews, the book contains three chapters by indus trial practitioners who describe in detail the operation of their processes and discuss the market for their products. Sections on the design of the pressure vessels and pumps required in these processes and on the acquisition of the data required for design are included. The costing of the processes is also discussed. There is good scope for combining a near-critical extraction step with other process steps in which the properties of near-critical solvents are utilised, for example as a reaction or crystallisation medium and a chapter is devoted to these important aspects. It is hoped that the work will be found to contain a great deal of specific information of use to those already familiar with this field. However the style of presentation and content is such that it will also be useful as an introduction. In particular it will be helpful to those wondering if this form of separation method has anything to offer for them, whether they are engineers, chemists or managers in industry, or in academic or research institutions.
