Hydrothermal process is an eco-friendly method for simultaneously extracting antioxidant
compounds and producing hydrochar. This study examined the simultaneous production of
nutritional compounds and hydrochar from Chlorella pyrenoidosa via a hydrothermal
process. The experiments were conducted using a batch reactor at varying temperatures
(160, 180, and 200° C) and holding times (10, 20, and 30 min). The results revealed that
phenolic contents, antioxidant activity, and hydrochar production were strongly affected by …
