Elsevier Science Cereal Straw As A Resource For Sustainable Biomaterials And Biofuels by Runcang Sun
By some estimates, at current usage fossil fuels could be exhausted around the year 2040. This has led to an increasing trend toward the use of renewable raw materials for the production of various products. Cereal straws, which consist of three different polymer entities, can supply renewable biomass that can be used in producing raw materials for the pulp and paper industry, transport fuels and chemical feedstock. This book describes the recent development of techniques for fractionation and conversion of cereal straws as environmental-friendly materials for industries. At the same time it is a comprehensive survey of straw chemistry. The first section describes the fundamentals of straw structure, its analysis and components. The second covers the extractives, which include isolation and structural characterization. The third focuses on hemicelluloses. Novel and environmentally friendly isolation and modification methods and the large-scale procedure of purification are covered. The fourth section covers the occurrence, structure, and chemical modification of cellulose from various straws. The fifth section deals with straw lignins, including their occurrence, structure and constitution, isolation and heterogeneity, and physico-chemical properties. The final section is concerned with utilization of straw and straw components after chemical modification. This is the first book on straw chemistry, providing the basics of straw composition and the structure of the cell walls. It provides the procedures to fractionate the straw components in order to produce chemical derivatives from straw cellulose, hemicelluloses, and lignin. It elucidates the new techniques for the production of biodegradable materials for the pulp and paper industries, the energy sector and chemical industry.
