Investigation of the Sustainable Production and Utilization of Biochar and Activated Carbon From Waste by Farah Yousef Taher Obar (19938288)

“…Out of the activated biochars tested, those produced without catalyst at 600 °C using either 2M KOH or 2% H₃PO₄ at a ratio of 1:1 of SCG were found to be the most efficient adsorbents with a BET surface area greater than 340 m² .g^-1, zeta potential of more than -75 mV and fixed carbon of 65%. …”
