Available in PDF, EPUB and Kindle. Book excerpt: Among terrestrial plants the vascular plants are the largest and the most con spicuous. Because of the presence of lignified supporting and conducting tissues such as xylem, terrestrial vascular plants can develop large upright forms. Composed mainly of xylem tissue, the stems of trees are characterized by elongated cells with thickened walls, impregnated by lignin. Diagrams of xylem cells (vessels, tracheids and fibers) can be seen in textbooks of plant anatomy (e. g. ESAU, 1953). A cross section of xylem tissue is shown in the section of this volume written by Professor FREUDENBERG (Fig. 1, p. 98). In general the occurrence of lignin in the plant kingdom is associated with the presence of these cells which comprise xylem. Thus lignin is found in vascular plants such as lycopods, ferns, gymnosperms and angiosperms, whereas it is absent from simple plants such as fungi, and from all other organisms. The mosses are an exceptional group which do not have the cells characteristic of xylem tissue but which contain lignin-like materials. These "moss lignins" have been discussed by Professor FREUDENBERG in this volume, and some doubts have been expressed as to whether or not they are true lignins (FR. * pp. 113-114). Work on the chemistry of lignin indicates that it is a polymer derived from the phenylpropanoid compound, coniferyl alcohol and related alcohols.

This book was released on 2015-08-11 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: As naturally occurring and abundant sources of non-fossil carbon, lignin and lignans offer exciting possibilities as a source of commercially valuable products, moving away from petrochemical-based feedstocks in favour of renewable raw materials. Lignin can be used directly in fields such as agriculture, livestock, soil rehabilitation, bioremediation and the polymer industry, or it can be chemically modified for the fabrication of specialty and high-value chemicals such as resins, adhesives, fuels and greases. Lignin and Lignans as Renewable Raw Materials presents a multidisciplinary overview of the state-of-the-art and future prospects of lignin and lignans. The book discusses the origin, structure, function and applications of both types of compounds, describing the main resources and values of these products as carbon raw materials. Topics covered include: • Structure and physicochemical properties • Lignin detection methods • Biosynthesis of lignin • Isolation methods • Characterization and modification of lignins • Applications of modified and unmodified lignins • Lignans: structure, chemical and biological properties • Future perspectives This book is a comprehensive resource for researchers, scientists and engineers in academia and industry working on new possibilities for the application of renewable raw materials.

Download or read book Fundamentals of Thermochemical Biomass Conversion written by R.P. Overend and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 1155 pages. Available in PDF, EPUB and Kindle. Book excerpt: Throughout the world many projects have been underway to investigate the conversion of renewable biomass into energy and synthetic fuels by thermo chemical methods such as combustion, pyrolysis, gasification and lique faction. While many of these represent prior art used during the early 20th century, the recent decade since the 1970s oil shock has immeasurably increased the knowledge base for such processes. Much of the new knowledge has been gained by persons who were not trained in classical wood chemistry and there have not yet been many attempts to synthesize the knowledge into a corpus of systematic information. To bring this about the International Energy Agency's Forestry Energy collaboration, the Gas Research Institute, the National Research Council of Canada and the US Department of Energy jointly sponsored a conference on the Fundamentals of Thermochemical Biomass Conversion in Estes Park, Colorado which was held on October 18-22, 1982. The Conference, which was structured around invited plenary papers and contributions from researchers, served as the basis for the papers in this volume which reflect the substantial conclusions of the Conference. During the planning for the Conference, it was realized by the editors in their capacity as Co-chairmen that a major problem in biomass research was the lack of reproducibility between reported experiments and their inter comparison on account of the heterogeneity of biomass materials. A well known wood chemist, George M.
Download or read book The Role of Catalysis for the Sustainable Production of Bio fuels and Bio chemicals written by Kostas Triantafyllidis and published by Newnes. This book was released on 2013-03-19 with total page 607 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Role of Catalysis for the Sustainable Production of Bio-fuels and Bio-chemicals describes the importance of catalysis for the sustainable production of biofuels and biochemicals, focused primarily on the state-of-the-art catalysts and catalytic processes expected to play a decisive role in the "green" production of fuels and chemicals from biomass. In addition, the book includes general elements regarding the entire chain of biomass production, conversion, environment, economy, and life-cycle assessment. Very few books are available on catalysis in production schemes using biomass or its primary conversion products, such as bio-oil and lignin. This book fills that gap with detailed discussions of: Catalytic pyrolysis of lignocellulosic biomass Hybrid biogasoline by co-processing in FCC units Fischer-Tropsch synthesis to biofuels (biomass-to-liquid process) Steam reforming of bio-oils to hydrogen With energy prices rapidly rising, environmental concerns growing, and regulatory apparatus evolving, this book is a resource with tutorial, research, and technological value for chemists, chemical engineers, policymakers, and students. Includes catalytic reaction mechanism schemes and gives a clear understanding of catalytic processes Includes flow diagrams of bench-, pilot- and industrial-scale catalytic processing units and demonstrates the various process technologies involved, enabling easy selection of the best process Incorporates many tables, enabling easy comparison of data based on a critical review of the available literature
Download or read book Topics in Dietary Fiber Research written by Gene Spiller and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of plant fibers and their effect on human physiology has suddenly, after many years of comparative obscurity, been catapulted to the forefront of the scien tific world. This new interest, first ignited by certain epidemiological reports, has been intensified by new re search and by dramatization in the lay press. To counter act the dissemination of inaccurate information and to elimi nate confusion, several authors have felt the need to make objective, unbiased reports available to the scientific community. The collection of papers in our own Fiber in Human Nutrition (Plenum Press, 1976) is one such effor~ However, even as it was going to press, we realized that increased interest in specific areas of fiber research necessitated a more detailed and up-to-date look at certain topics. This book is directed to that purpose. The first volume of Fiber in Human Nutrition was de signed as a basic reference textbook covering the entire spectrum of plant fibers from chemical, analytical, physico chemical, physiological, medical and epidemiological points of view. The present volume, which enlarges on specific aspects of dietary fiber, is offered as a supplement to Fiber in Human Nutrition. Together, the two volumes should be a most valuable source of information for the student of the scientific intricacies of fiber. An ongoing concern is that many of the substances dealt with in these and other "fiber" books are not, in the clas sical sense, of a fibrous nature at all.

Download or read book Modern Chemical Technology and Emission Control written by M.B. Hocking and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 474 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text of applied chemistry considers the interface between chemistry and chemical engineering, using examples of some of the important process in dustries. Integrated with this is detailed consideration of measures which may be taken for avoidance or control of potential emissions. This new emphasis in applied chemistry has been developed through eight years of experience gained from working in industry in research, development and environment al control fields, plus twelve years of teaching here using this approach. It is aimed primarily towards science and engineering students as well as to envi ronmentalists and practising professionals with responsibilities or an interest in this interface. By providing the appropriate process information back to back with emis sions and control data, the potential for process fine-tuning is improved for both raw material efficiency and emission control objectives. This approach also emphasizes integral process changes rather than add-on units for emis sion control. Add-on units have their place, when rapid action on an urgent emission problem is required, or when control simply is not feasible by pro cess integral changes alone. Obviously fundamental process changes for emission containment are best conceived at the design stage. However, at whatever stage process modifications are installed, this approach to control should appeal to the industrialist in particular, in that something more sub stantial than decreased emissions may be gained.
