Özet
Hydrothermal pretreatment is an effective method to increase the energy density of biowastes with high moisture content. Since the hydrothermal pretreatment slightly modifies the lignocellulosic structure, the thermochemical conversion behavior of the biomass also changes. In the present study, grape pomace (GP) and fermentation sludge (FS) were hydrothermally pretreated at 220°C and 90 minutes. The fuel properties, pyrolysis, and combustion behaviors of the corresponding hydrochars were compared. After pretreatment, the fixed carbon content (wt%) of GP increased by 7.2% and that of FS by 16.8%, while the ash content (wt%) of GP decreased by 77.6% and that of FS by 38.8%. Due to a decrease in both H/C and O/C, the heating value of GP and FS increased by 11% and 36%, respectively. Upon pretreatment, ignition temperatures were shifted from 245.8°C to 295.8°C for GP and 273°C to 279°C for FS …
