4. Conclusion
In this study, carbonaceous samples have been prepared by hydrothermal carbonization of bamboo.
Preliminary study has shown that a thorough carbonization process can take place during hydrothermal
treatment at relatively mild conditions, evidenced by the stark change in the heating value of the samples,
which is a consequence of the rearrangement of the chemical bounds, especially those between carbon,
oxygen and hydrogen. The HTC treatment can develop rough surface and porous structure of the
obtained biochar. The coal-like solid particles produced during the treatment may be used as fuels, or
alternatively suitable for adsorption purposes because of its structure. Additionally, limited analysis of
the process water suggested there may be a vast amounts of compounds dissolved in the liquid phase.
The liquid phase contained nutrients that may be useful as fertilizer.
From this preliminary work, HTC appeared to be a conversion technology that is worth serious attention
due to potential of its possible applications.
