Dwarft green coconut husk ash (DGCHA) was used as a bio-adsorbent for acid value reduction of Croton heliotropiifolius Kunth leaves oil (CHKLO). A novel, highly potassium-based catalyst was derived from Karpuravalli banana peels (KBP), calcined, and characterized using TGA, ZETA, FTIR, SEM-EDX, XRF-FS, and BET analysis.
