Abstract

As heat is applied to wood, thermal degradation, called pyrolysis, occurs. A majority of what is known about the pyrolysis of wood has been obtained using either extracted component polymers or wood pyrolyzed in an inert atmosphere. However, the physical and chemical reactions that occur during pyrolysis of wood are affected by the interaction of the polymers in whole wood as well as the oxygen present in the atmosphere. X-ray photoelectron spectroscopy (XPS) is a surface measurement technique that yields information on both the chemical composition of the sample and the chemical bonds among the elements and compounds that comprise it. Here, XPS was used as a tool to examine the number and type of carbon bonds in Douglas fir exposed to flaming combustion.
