Abstract: Water hyacinth (WHs), which is a crucial waste material from agriculture in Thailand. It consists of hemicellulose, cellulose and lignin that has a potential for carbon material production. In this research, carbon material was prepared from Water hyacinth via hydrothermal Carbonization (HTC) by study the effect of hydrothermal temperature 200 °C, reaction time (4-24 h) and using H3PO4 activation to develop porosity and surface area. The sample have been characterized chemical-physical properties of carbon nanoporous materials through a scanning electron microscope (SEM), fourier transformer Infrared spectroscopy (FT-IR), X-ray diffraction (XRD). The results revealed that carbon content of nanoporous carbon materials from water hyacinth were increased with higher HTC temperature and time. Performing HTC at 200 °C for 12 h and using H3PO4 activation catalyst shows porosity increased on char surface is the optimum condition to synthesis of precursor materials for good adsorbent.

Key words: Water hyacinth, hydrothermal carbonization, nanoporous carbon, adsorbent.
