Pyrolysis of wood components

As lignin and especially cellulose are used in different industrial applications, many investigations on these wood components are performed by means of thermal analysis. Only a few examples can be cited here, some more are found in the following sections, mainly in connection with fire retardments. 

Lignins as byproducts in the paper industry are mainly used for heating due to their combustibility but there is intensive research for other, ecologically more sensible applications [43]. The molecular structure of lignins is very complex and until now not fully resolved. This lack originates from the effect that lignins can be neither isolated completely from the other components, nor the structure be reserved when it is split into the monomeric parts (for a review of literature see 

DTA analyses proved that the size and the position of endo- and exothermic peaks in the thermograms of lignin depended on the way lignin was prepared
