Abstract

The effects of lignin removal on hydrochar were investigated by comparing the structural, chemical, and thermal characteristics of holocellulose and wood powder-derived carbon materials (hydrochar). The hydrochar samples were obtained from hydrothermal carbonization (HTC) of holocellulose and wood powder at 210–230 °C for 9 h. The characteristics of the obtained products were characterized by scanning electron microscopy, X-ray diffraction, Fourier transform infrared spectroscopy, elemental analysis, and thermogravimetric analysis. The observations reveal that the onset temperature of the HTC of holocellulose is lower than that of wood powder. The holocellulose-derived hydrochar samples exhibit higher carbon content and thermal stability with higher coalification degree and less complex chemical composition compared with resultant products based on wood powder. These results reveal that the holocellulose is easier to be disintegrated and hydrocarbonized without the shielding effects of lignin and suggest that the lignin removal is beneficial for increasing the rate and efficiency of the polysaccharide in biomass converting into hydrochar.
