The Chemical Technology of Wood is an eight-chapter introductory text on the developments in understanding the chemistry of wood and its chemical-technological utilization. The opening chapters of this book cover the productive aspects of forests, followed by a description of the anatomy and physical properties of wood. The subsequent chapter presents a summative wood analysis concerning its cellulose, hemicelluloses, lignin, and other extraneous components. This topic is followed by a presentation of several destructive processing of wood, including acid hydrolysis, pyrolysis, oxidation, and hydrogenolysis. The remaining chapters describe the pulp production through sulfite cooking and using alkaline reagents. This book will prove useful to chemists, engineers, biologists, foresters, and economists.

Pulp and Paper Industry: Chemical Recovery examines the scientific and technical advances that have been made in chemical recovery, including the very latest developments. It looks at general aspects of the chemical recovery process and its significance, black liquor evaporation, black liquor combustion, white liquor preparation, and lime reburning. The book also describes the technologies for chemical recovery of nonwood black liquor, as well as direct alkali regeneration systems in small pulp mills. In addition, it includes a discussion of alternative chemical recovery processes, i.e. alternative causticization and gasification processes, and the progress being made in the recovery of filler, coating color, and pigments. Furthermore, it discusses the utilization of new value streams (fuels and chemicals) from residuals and spent pulping liquor, including related environmental challenges. - Offers thorough and in-depth coverage of scientific and technical advances in chemical recovery in pulp making - Discusses alternative chemical recovery processes, i.e., alternative causticization and gasification processes - Covers the progress being made in the recovery of filler, coating color, and pigments - Examines utilization of new value streams (fuels and chemicals) from residuals and spent pulping liquor - Discusses environmental challenges (air emissions, mill closure) - Presents ways in which the economics, energy efficiency, and environmental protection associated with the recovery process can be improved

Pulp and paper production has increased globally and will continue to increase in the near future. Approximately 155 million tons of wood pulp is produced worldwide and about 260 million is projected for the year 2010. To be able to cope with increasing demand, an increase in productivity and improved environmental performance is needed as the industry is also under constant pressure to reduce and modify environmental emissions to air and water. The authors give updated information on various biotechnological processes useful in the pulp and paper industry which could help in reducing the environmental pollution problem, in addition to other benefits. Various chapters deal with the latest developments in such areas as raw material preparation, pulping, bleaching, water management, waste treatment and utilization. The book also covers the environmental regulations in various parts of the world as well as the role of biotechnology in reducing environmental problems.

Separation processes—or processes that use physical, chemical, or electrical forces to isolate or concentrate selected constituents of a mixture—are essential to the chemical, petroleum refining, and materials processing industries. In this volume, an expert panel reviews the separation process needs of seven industries and identifies technologies that hold promise for meeting these needs, as well as key technologies that could enable separations. In addition, the book recommends criteria for the selection of separations research projects for the Department of Energy's Office of Industrial Technology.
