摘要：

Carbonaceous materials were produced by means of the hydrothermal carbonization of cotton pulp fiber at temperatures in the 245-305 degrees C range. The morphology, chemical and structural characteristics of the hydrothermally carbonized products were investigated with scanning electron microscopy (SEM), X-ray diffraction, Fourier-transform Infrared Spectrometer (FTIR) and X-ray photoelectron spectroscopy (XPS). The hydrothermal product of cotton pulp fiber is made up of carbonaceous microspheres (size: 3-8 mu m). The carbonaceous microspheres have different chemical structure with one of cotton pulp fiber and have amorphous structure. The surface of carbonaceous microspheres contains a high concentration of reactive oxygen groups.
