Available in PDF, EPUB and Kindle. Book excerpt: Petroleum-based industrial products have gradually replaced products derived from biological materials. However, biologically based products are making a comebackâ€"because of a threefold increase in farm productivity and new technologies. Biobased Industrial Products envisions a biobased industrial future, where starch will be used to make biopolymers and vegetable oils will become a routine component in lubricants and detergents. Biobased Industrial Products overviews the U.S. land resources available for agricultural production, summarizes plant materials currently produced, and describes prospects for increasing varieties and yields. The committee discusses the concept of the biorefinery and outlines proven and potential thermal, mechanical, and chemical technologies for conversion of natural resources to industrial applications. The committee also illustrates the developmental dynamics of biobased products through existing examples, as well as products still on the drawing board, and it identifies priorities for research and development.

Download or read book Wood Pellet as a Renewable Source of Energy written by Mohammad Ali Abdoli and published by Springer. This book was released on 2018-05-30 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book takes the reader on a journey from the moment that raw wood material enters the factory to the final pellet consumption. It starts by reviewing biomass application and its role for the future development of renewable energies, discussing different biomass conversion methods as alternatives to direct utilization. The second chapter then comprehensively examines densification processes, with a focus on the pelleting process. Chapter three further elaborates on the pelleting process, including an overview of the pellet structure and properties, and the history of this process. The subsequent chapters provide a detailed account of the production process from raw material delivery to final distribution, addressing the chemical and physical quality, and presenting measurement methods and standards. In the final chapters, the authors describe in detail the pellet combustion process and emissions.

Available in PDF, EPUB and Kindle. Book excerpt: Future Sources of Organic Raw Materials: CHEMRAWN I is a collection of lectures presented at the World Conference on Future Sources of Organic Raw Materials, held in Toronto, Canada, on July 10-13, 1978. The conference focused on potential future sources of organic raw materials such as non-conventional fossil hydrocarbons, coal, industrial and agricultural wastes, and renewable resources like wood and other plant materials. This book is comprised of 52 chapters and opens with an assessment of the likely future availability of conventional oil and gas as they relate to possible demands for petrochemical feedstocks, paying particular attention to the availability and demand patterns for fossil hydrocarbons. The following chapters discuss the reserves and worldwide distribution of oil shale and tar sands; climate and its impact on renewable resources; research and management of natural resources; and production of chemicals directly from synthesis gas. Pyrolysis of solid carbonaceous materials is also considered, along with natural rubber production and biomass for non-food use. This monograph will be a useful resource for organic chemists and energy policymakers.

Download or read book Renewable Raw Materials written by Roland Ulber and published by John Wiley & Sons. This book was released on 2011-04-27 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the main challenges facing the chemical industry is the transition to sustainable operations. Industries are taking initiatives to reduce resource intensities or footprints, and by adopting safer materials and processes. Such efforts need to be supported by techniques that can quantify the broad economic and environmental implications of industrial operations, retrofi t options and provide new design alternatives. This contemporary overview focuses on cradle-to-grave life cycle assessments of existing or conceptual processes for producing valueadded fuels, chemicals, and/or materials from renewable agricultural residues, plant-derived starches and oils, lignocellulosic biomass, and plant-based industrial processing wastes. It presents the key concepts, systems, and technologies, with an emphasis on new feedstocks for the chemical industry. Each chapter uses common themes of specifi c raw materials, thus forming a natural progression throughout the book. The result is coverage from a wide range of perspectives, emphasizing not only the technical issues but also considering the market place and socio-economic aspects.

Download or read book Chemistry in the Utilization of Wood written by R. H. Farmer and published by Elsevier. This book was released on 2013-10-22 with total page 211 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chemistry in the Utilization of Wood deals with the chemistry of wood and its technical and practical applications. It shows how the chemical nature of wood influences its properties and utilization, both as a constructional material and as the raw material for the manufacture of secondary products such as pulp and paper, cellulose derivatives, and board materials. Comprised of 12 chapters, this volume begins with an introduction to the chemical nature of wood, including a brief treatment of its anatomical structure. The discussion then turns to the chemistry of wood cell wall components such as cellulose, hemicellulose, and lignin; the principles of the methods employed in wood analysis, with emphasis on the determination of moisture content and extractives, cellulose, pentosan, and other polysaccharides; the influence of extractives on the properties and utilization of wood; and the use of timber in conjunction with chemicals. Other chapters deal with the conversion of wood into chemical products; corrosion of metals in association with wood; and the relationship between wood and water. The chemical aspects of wood attack by fungi and insects are also considered, along with destructive distillation of wood. This book is primarily intended for technical men in the wood-using industries who have an interest in wood and some knowledge of chemistry, and for students entering any field of wood technology.
Download or read book Biological Utilization of Wood for Production of Chemicals and Foodstuffs written by George J. Hajny and published by . This book was released on 1981 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the long term, mankind will have to depend on solar energy and photosynthetic processes rather than on fossil materials for energy and material needs. Cellulose and the hemicelluloses, which make up about 70 percent of the dry matter of trees and shrubs, are the most abundant, renewable, raw materials on earth. At present, the highest uses of wood are for structural material and as a source of fiber. There are, however, large quantities of wood residues produced during harvesting and manufacture that might be used. Intensive silviculture can greatly increase the supply of wood for all purposes. This paper reviews the work the U.S. Forest Products Laboratory has done over nearly 70 years to produce chemicals and feedstuffs from wood residues. Wood has been converted successfully to fermentation chemicals such as ethyl alcohol, glycerol, arabitol, erythritol, butanol, acetone, and 2,3-butylene glycol as well as to feedstuffs such as molasses and yeast, and to wood modified to make the polysaccharides digestible by ruminants. At present such use of wood is economically marginal, but is potentially economic in the future. (Author).
