摘      要：This study investigates the simultaneous production of hydrochar and bioactive compounds from Ulva lactuca via a hydrothermal *** experiment was carried out using a batch reaction vessel at different reaction temperatures of 180-220◦C and various holding times of 30-90 *** expected,both temperature and time vigorously influenced hydrochar and bioactive compound *** maximum hydrochar yield was at 32.4 wt%.The higher heating value(HHV)of hydrochar was observed in the range of 17.68-21.07 MJ kg^(-1),near the energy content of low-rank *** hydrochars exhibited contact angles higher than 90°(i.e.,94-108°)for a longer time,confirming their hydrophobic *** scanning electron microscope analysis(SEM)showed that the hydrothermal process enables cracks in the spherical shape of raw *** into small and porous *** producing hydrochar,the hydrothermal process of *** also gives promising antioxidants and phenolics as bioactive *** highest total phenolic content and antioxidant activity could be achieved in hydrolysate at 200℃and 30 min with the value of 1.20±0.12 mg/g and 71.6±1.3%,respectively.
