Upgrading fuel potentials of waste biomass via hydrothermal carbonization

In recent decades, massive exploitation of fossil fuels caused a growing demand for the production energies from renewable sources. Hydrochar obtained waste biomass via hydrothermal carbonization (HTC) possesses good potentials as biofuel. Therefore, we performed HTC corn cob, paulownia leaves, and olive pomace at different temperatures (180, 220, 260oC). The main goal this study was to comparatively evaluate influence conditions on structure fuel characteristics solids. results showed that yields hydrochar decrease significantly with increasing temperature in all samples. carbon content higher heating value increased reached highest values hydrochars 260?C, while volatile matter decreased. Furthermore, Van Krevelen diagram reveals transformation feedstock lignite-like products upon achieved. study, processes dehydration decarboxylation during provoke intensive have enhanced properties fewer volatiles compared feedstock.
