The Chemical Technology of Wood
Author: Harmann Wenzl
Publisher: Elsevier
ISBN: 0323143121
Category : Technology & Engineering
Languages : en
Pages : 711
Book Description
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.

Preliminary Investigation Into Single Stage Enzyme Free Hydrolysis of Hardwood Sawdust

ISBN:
Category : Fermentation
Languages : en
Pages : 63
Book Description
Enzymatic hydrolysis is the most common method of producing fermentable sugars from lignocellulosic biomass. Limitations to this step include the high cost of enzymes, and the time required to process the biomass. To increase the throughput and decrease catalyst cost, the preliminary development of a continuous concentrated sulfuric acid process is explored. The process requires two distinct steps. The first step involves hydrolyzing lignocellulose to fermentable sugars, glucose and xylose. The second step consists of glucose and xylose removal from the concentrated acid stream. The separation of sugars decreases the production of reaction byproducts and allows for the recycle of acid to the process. Single stage acid hydrolysis was tested at nine different reaction conditions. The optimum reaction condition occurred at 70 weight percent acid and 80°C with 58.2 percent glucose release as a percentage of available glucan and 86.5 percent xylose release as a percentage of available xylan. Detection of xylose and glucose in solution occurred at different times. These peaks are separated by enough time to warrant continuous removal of produced glucose and xylose to limit the production of reaction byproducts. In order to optimize this reaction condition, a limit of 63 percent glucose release as a percentage of available glucan was observed. A preliminary investigation of Dowex Monosphere 99 ion exchange resin to separate glucose and xylose from 70 weight percent was performed. At the column conditions tested, the sulfuric acid caused shrinkage and deactivation of the ion exchange resin leading to inefficient separation of glucose and xylose.
