Pyrolysis of Biomass

With the development of societies fossil energy is no longer the only energy resource, and increasing attention had been paid to alternative energy. Biomass is considered to be one of the alternatives due to efficiency and low cost. This book presents biomass pyrolysis behavior for three main components: Cellulose, Hemicellulose and Lignin, and discusses the influence of mineral salts , zeolite catalysts and metal oxide on their pyrolysis.

Résumé
"Das Buch eignet sich für alle Leser, die vor allem einen Zugang zum chemischen Geschehen der Pyrolyse von Biomasse erhalten wollen. Darin liegt der besondere Wert dieses Bandes, mit dem er sich gegenüber anderen Monographien auch deutlich absetzt. Dies können sowohl Einsteiger in das Thema sein, aber auch Fachleute, die einen tieferen Einblick in das chemische Reaktionsgeschehen der Pyrolyse von Lignocellulose und ihrer Bestandteile erhalten wollen."
