Effects of hydrothermal temperature and time of hydrochar from Cattail leaves

Abstract

Hydrochar have been successfully synthesized from Cattail leaves via hydrothermal carbonization. This research study the effect of hydrothermal temperature (160-200 °C) and reaction time (4-24 h) to develop porosity and surface area. The sample have been characterized by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR) and Raman spectroscopy were employed to characterize morphology, surface function and disorder in carbon structure respectively. The results revealed that hydrothermal-carbonization process affect on the properties of hydrochar. The hydrothermal temperatures and time were increased resulted in the decomposition of hydrochar gradually increased amorphous carbon and aromatic groups on surface of hydrochar. Cattail leaves was hydrothermal carbonization at 200 °C for 12 h resulted in the most degradation of hemicellulose and cellulose.
