The torrefaction experiments were carried out using two typical wood-based panel wastes: Plywood (PW) and Fiberboard (FB). The influences of torrefaction on chemical structure and fuel property of wood-based panel wastes were researched using the analytical characterization by combining with the element, calorific value, Fourier transform infrared spectroscopy (FTIR), two-dimensional correlation infrared spectroscopy (2D-PCIS) and X-ray photoelectron spectroscopy (XPS). The results show that the chemical structure of PW and FB do not change a lot at 200℃ even at 250℃, but at 300 ℃, significant changes will occur. With the increase of torrefaction temperature, the low-energy states of "-C-H/-C-O/-C=O" change into the high-energy states of "aromatic -C-C/-C=C", and the calorific value of torrefied solid increases significantly. Simultaneously, at 300 ℃, PW and FB obtain the maximum denitrogenation rate, which is 75.04 % and 72.48 %, respectively.
