Chemistry of Lignocellulosics


Book Description

This book presents the chemical properties of lignocellulosic fibers, knowledge of which is essential for innovation and sustainable development of their transformation. Thermochemical transformation of wood and other lignocellulosics is presented to highlight its volatile, liquid and solid products and their novel applications. Forest biorefinery is described to emphasize the new products from lignocellulosic constituents, both structural (cellulose, hemicelluloses and lignins) and those extraneous to cell walls-extractives. New developments in cellulose technology related to nanocellulose are discussed in relation to new applications. Industrial lignins are presented in detail, both in terms of extraction procedures from spent liquors and structural characterization of the isolated lignins. Application of lignocellulosic biopolymers in new composite materials, or in biomaterials for medicinal purposes, and in solid wood preservation, are described. The example of an industrial biorefinery installed in southwestern France more than 40 years ago is presented.

Characterization of Lignocellulosic Materials


Book Description

Lignocellulosic materials are a natural, abundant and renewableresource essential to the functioning of industrial societies andcritical to the development of a sustainable global economy. Aswood and paper products, they have played an important role in theevolution of civilization. Improvement of the quality andmanufacturing efficiency of such products has often been hamperedby the lack of understanding of the complex structures and chemicalcompositions of the materials. Due to increasing economic and environmental issues concerning theuse of petrochemicals, lignocellulosic materials will be reliedupon as feedstock for the production of chemicals, fuels andbiocompatible materials. Significant progress has been made to uselignocellulosic materials for the production of fuel ethanol and asa reinforcing component in polymer composites. Effective andeconomical methods for such uses, however, remain underdeveloped,partly due to the difficulties encountered in the characterizationof the structures of native lignocelluloses andlignocelluloses-based materials. Improved methods for thecharacterization of lignocellulosic materials are needed. Characterization of Lignocellulosic Materials covers recentadvances in the characterization of wood, pulp fibres and papers.It also describes the analyses of native and modifiedlignocellulosic fibres and materials using a range of advancedtechniques such as time-of-flight secondary ion mass spectrometry,2D heteronuclear single quantum correlation NMR, and Ramanmicroscopy. The book provides a survey of state-of-the-artcharacterization methods for lignocellulosic materials, for bothacademic and industrial researchers who work in the fields of woodand paper, lignocelluloses-based composites and polymer blends, andbio-based fuels and materials.
