The book is divided into seven chapters. It follows the thread of the three majorcomponents of biomass and systematically illustrates the theories involved in biomasspyrolysis liquefaction. This book begins with the structure of lignocellulosic biomass.The basic structure， physical and chemical properties of the three major componentsof biomass， namely cellulose， hemicellulose and lignin， are introduced in detail， andcommon model compounds of the three major components as well as their proper-ties and corresponding extraction methods are also expounded in the first chapter.Then from Chapter 2 to Chapter 4 we give an in-depth illustration of the pyrolysismechanism of the three major components of biomass. Beginning with the basic pro-cess of pyrolysis， the influence of different factors on biomass component pyrolysis iselaborated， and the biomass component pyrolysis mechanism is discussed based onkinetics research， product formation processes and theoretical simulation at molecular level. Chapters 5 and 6 introduce the influence of the interaction of components，catalysts and inorganic salts on the pyrolysis behavior of biomass. Finally， pyrolysisbehavior and pyrolysis liquefaction characteristics of different biomass species are illustrated， and research about bio-oil graded upgrading based on the separation of bio-oil is presented in Chapter 7.
