FT-IR imaging was used to monitor the structural and chemical changes of wood particles under various pyrolysis conditions. The temperature or reaction profile inside pyrolyzed wood was obtained from a novel approach using chemical images coupled with multivariate analysis. Poplar sections 100 µm thick were pyrolyzed at 250-500 °C and the resulting FT-IR images were used as standards to determine the temperature in a poplar wood block (5 mm × 5 mm × 20 mm). Principal component analysis (PCA) and partial least-squares (PLS) regression were used to develop predictive models to map the temperature profile in the pyrolyzed wood. The results indicate that FT-IR imaging coupled with multivariate analysis is a powerful tool to study the heat transfer effects in the pyrolysis of thick wood particles. We believe that this is a unique and novel approach to visualize the chemical changes in heated biomass and thermal effects in other materials. 1 Energy & fuels 25 ARTICULO Bahng, Mi-Kyung 45072 Donohoe, Bryon s. 42719 Nimlos, Mark R. 42718 174415 174415 0 0 0 0 242234 BAAB BAAB 2026-03-05 200052431 0 200052431 2026-03-05 16:11:50 2026-03-05 ARTICULO
