    Abstract

    The problem encountered in solid biofuels is their low quality especially in terms of heating value. One treatment can improve this quality by employed a hydrothermal processes. This study aims to determine the effect of a hydrothermal treatment of Terminalia catappa peels waste on the heating value and chemical composition. Hydrothermal experiment was executed in Bioenergy Laboratory of Janabadra University. This experiment was conducted on temperature variations of 160°C and 220°C with a holding time of 30 and 60 minutes. The water and biomass ratio used is 1:4. The heating value and proximate analysis furthermore is conducted. The highest heating value is generated at a temperature variation of 220° C with a holding time of 60 minutes by 4,675.25 cal/gram. This value meets the Austrian solid fuel heating value standard (ONORM M 7135) i.e. ≥ 4,299.5 cal/gram. In the proximate analysis composition, the product showed a decrease in water content, ash content, volatile matter and an increased in carbon content along with an increasing temperature variation and its holding time. In this variation, the water content had reached 6.41%, volatile level of 51.8%, ash content of 2.2%, and carbon content of 39.59%. These results indicate significant improvement in the quality of solid fuel. Therefore, the hydrothermal is able to answer the alternative fuels’ needs that are environmentally friendly.
