Abstract

This chapter explores condensed phase reactions important to thermal deconstruction, first by noting common physical and chemical transformations among different thermochemical processes. It attempts to unify a wide spectrum of thermochemical processes in terms of the fundamental thermal deconstruction mechanisms that occur in the condensed phase of biomass. Thermal deconstruction of biomass is integral to several kinds of processes for which heat is the driving force of physical and chemical transformations. Many of the most important transformations occur in the condensed phase – with solid biomass depolymerizing and decomposing into liquids, vapors, gases, and solid residue – although secondary reactions of vaporized species can also be important in determining the ultimate yields of products. Despite similarities, thermochemical processes can be categorized according to whether the principal products are gases (combustion and gasification), liquids (pyrolysis and solvent liquefaction), or solids (torrefaction and slow pyrolysis), although they all produce smaller amounts of the other products as well.
