Abstract The catalytic pyrolysis of green algae (GA) was conducted using both a thermogravimetric analyzer and horizontal tube reactor. Five catalysts – biochar, potassium hydroxide (KOH), sodium (NaOH), ethylene glycol dimethyl ether (EGDE), Zeolite Socony Mobil‐5 (ZSM) were tested. Kinetic analysis performed the Friedman method to estimate activation energy, master plot method, combined with regression analysis, employed determine suitable reaction model. products quantitatively characterized. results showed that presence influenced kinetic parameters product yields. Activation energy values for noncatalytic GA sample ranged from 124.92 299.39 kJ mol −1 , whereas samples exhibited broader range 110.79 358.30 . use generally increased solid liquid yields, this accompanied by decline in gas yield. volumetric yield gaseous components temperature. Among these gases, CO 2 had highest yield, followed CO, CH 4 H C 3 6 These highlight role influencing process
