Abstract: Hydrothermal carbonization (HTC) of biomass is a process whereby cellulosic materials are heated over the temperature range of 180-300 degrees in the presence of water, giving hydrochar products of improved fuel properties. This work was concerned with the preparation and characterization of hydrochars produced from coconut shell in a batch autoclave reactor. The variables studied included treatment time (90-270 min) and temperature (150-250 degrees) and the weight fraction of coconut shell in the mixture (0.25-0.50). Hydrochar yields and various properties of the char products, including proximate analysis, heating value and solid density, were determined. The central-composite-design (CCD) was used to design the number of experimental conditions and the response surface methodology (RSM) was employed for developing the empirical correlations relating hydrochar properties with HTC conditions.
