Abstract

The study of microstructure and chemical composition of carbonized wood has an important meaning for its application. Changes in microstructure and chemical composition of compressed and carbonized poplar（Populus euramevicana） were studied using a scanning electron microscope （SEM），Energy-dispersive X-ray spectrum （EDS） Analysis，and Fourier Transform Infrared （FTIR） Spectroscopy. Results showed that after Poplar was compressed and carbonized，to maintain cell wall integrity the cell cavity and the distance between the cell walls，which reduced 56.94%，53.34% at maximum，noticeably diminished. Element content in the sapwood and the heartwood varied similarly after hot-pressing and after carbonization with carbon content increasing and oxygen content decreasing. For example，the C-over-O ration of untreated wood was 1.76，after compressed and carbonized，the ration reduced to 1.65 and 1.45. Cellulose and hemicellulose degradation led to a reduction in peak absorption intensity for CH and C=O during hot-pressing and carbonization with some displacement also taking place. In addition，the change in peak absorption intensity for a benzene ring and phenolic-ether bond illustrated a chemical change in lignin. Thus，after carbonization in the heartwood，the new absorption peak located near the wave number at 2 853 cm-1 indicated that during this treatment a complicated chemical reaction had generated new chemical groups.［Ch，9 fig. 1 tab. 15 ref.］
