Hydrothermal carbonization (HTC) is known as a thermochemical process that used for converting wet biomass into a coal-like solid fuel (hydrochar). Hydrochar is easily crumbled. Because of hydrophobic, hydrochart is uneasily degraded by microorganisms. It has a calorific value comparable to lignite coal. In this study, hydrochar was made via converting organic fraction of municipal solid waste throuh hydrothermal carbonization (HTC) at 190, 210, and 230 oC for 30 min with feed to water ratio (FWR) 0.1, 0.2, 0.3. The feedstock processed include food waste, paper, wood waste represented as pseudo-component of organic fraction of MSW. The high heating value (HHV), FTIR, proximate and ultimate analysis were applied both to feedstock and hydrochar. The results showed that the energy dense of hydrochar elevated with increasing HTC temperature. Energy densification ratio and heating value increased by approximately 1.0-1.32 and 30% over raw feedstock. The lower yields of hydrochar obtained at higher temperature. Typical char yields for lignocellulosic material range between 62-63 wt% at 190 °C and reduce to 54-57 wt% at 230 °C. Furthermore, preliminary study of kinetic model for lignocellulose decomposition has been determined. This model based on rate of mass loss of lignocellulose compound in hydrothermal carbonization of MSW. Three parallel first-order reactions have been shown to illustrate the mass hydrochar yield for temperatures at 190, 210, and 230 oC. Lignocellulose degradation is described by first order rate constant with activation energy 76.26 kJ/mol, 51.86 kJ/mol, 12,23 kJ/mol for lignin, cellulose, and hemicellulose decomposition, respectively.
