Effect of Hydrothermal Carbonization on Fuel and Combustion Properties of Shrimp Shell Waste

Shrimp shell is a popularly consumed seafood around the globe which generates substantial quantity of solid wet waste. Hydrothermal carbonization (HTC) could be viable pathway to convert shrimp waste into energy-dense hydrochar. The present study aims assess fuel properties, physicochemical attributes, and combustion properties hydrochar generated with wide range HTC temperatures (110–290 °C). Results showed that rise in rate results decline mass yield as low 25.7% increase temperature. Thermogravimetric analysis indicates hydrochars more thermally stable than raw dried feedstock. from bomb calorimeter report maximum HHV 27.9 MJ/kg for SS-290, showing 13% energy densification compared shell. slagging fouling indices determined further assisted addressing concern regarding increasing ash content changing 17.0% 36.6%. Lower ratings index, alkali chlorine at higher temperature indicate reduced probability reactor during combustion. findings demonstrate promising approach transforming potential replacement.
