Abstract

Waste cooking oil (WCO) energy development offers an effective method for producing renewable fuels, enabling simultaneous resource recovery and pollution reduction. This study aims to develop a novel bimetallic Fe(Ni)-Ru/ZSM-5 catalyst toward H₂-rich syngas production from WCO. The results show that Fe-Ru/ZSM-5 produced a higher maximum H₂ yield (84.05 μmol·g_cat.⁻¹·s⁻¹) than did Ni-Ru/ZSM-5 (41.76 μmol·g_cat.⁻¹·s⁻¹) when fed at a 50 L/min rate at an optimal temperature of 700 °C. Fe-Ru/ZSM-5 presented a more prolific microporous distribution, whose structure contributes to the diffusion of the short-chain hydrocarbon intermediate reactants to enhance hydrogen production. Fe(III) can help to improve the conversion ratio of benzene and the anti‑carbon deposition capability of the catalyst. The dealumination and oxidation decreases the stability of the catalyst and may lead to inactivation. Furthermore, this study discusses the mechanism of bimetallic-loaded catalysts combining noble metals with transition metals in WCO pyrolysis. The results point to effective new approaches to increase H₂ production through the catalytic pyrolysis of WCO.
