The valorization of biowaste like tea residues through catalytic pyrolysis is critical for advancing circular bioeconomy, yet challenges remain in achieving efficient co-production of high-quality liquid fuels and clean energy gases. For the first time, the catalytic pyrolysis of black tea residue over ZSM-5-supported Cu-Co catalysts was systematically investigated, demonstrating a sustainable approach to simultaneously produce aromatic hydrocarbon-rich liquid oil and methane-enriched hydrogen through an eco-friendly process. Bimetallic Cu-Co c...
