Hydrothermal carbonization of waste biomass for energy generation
In this study,hydrothermal carbonization was used to upgrade waste biomass at temperatures ranging from 150 to 375 ℃ and a residence time of 30 minutes.The kinetics of hydrothermal carbonization was investigated and fuel properties of produced hydrochars were evaluated.The kinetic study indicated that hydrothermal carbonization of biomass followed first-order reaction rate with the apparent activation energy of 67.41 and 179.54 kJ/mol for coconut fiber and 59.18 and 173.70 kJ/mol for eucalyptus leaves within the temperature ranges of 150-300℃ and 300-375 ℃,respectively.Hydrothermal carbonization narrowed the differences in fuel properties among different biomass feedstocks.The fuel qualities of hydrochars were significantly improved:increased ignition temperatures and elevated combustion temperature regions compared to raw biomass feedstock.The present study showed that hydrothermal carbonization was a promising conversion process for the production of the hydrochars which had increased fuel qualities compared to raw biomass.
