The thermochemical behavior of pine wood (Pinus sylvestris) and its main structural constituents (cellulose, hemicelluloses, and lignin) was investigated by pyrolysis-gas chromatography with mass-selective detection (Py-GC/MSD). In each case, major GC-amenable pyrolysis products were classified into several compound groups, and changes in the relative mass portions of these monomer-related fragments were monitored in the temperature range 400–1000 °C. The formation of the main products was shown to be characteristically dependent on the reaction temperature. The results also indicated that in the temperature range used, wood appeared to behave as the sum of its constituents.
