Abstract The synthesis of high‐efficiency and low‐cost catalysts for hydrodeoxygenation (HDO) waste lignin to advanced biofuels is crucial enhancing current biorefinery processes. Inexpensive transition metals, including Fe, Ni, Cu, Zn, were severally co‐loaded with Ru on HY zeolite form bimetallic bifunctional catalysts. These subsequently tested HDO conversion softwood several model compounds. Results indicated that the inexpensive earth‐abundant metals could modulate hydrogenolysis activity decrease yield low‐molecular‐weight gaseous products. Among these catalysts, Ru‐Cu/HY showed best performance, affording highest selectivity hydrocarbon improved catalytic performance was probably a result following three factors: (1) high total strong acid sites, (2) good dispersion metal species limited segregation, (3) adsorption capacity polar fractions, hydroxyl groups ether bonds. Moreover, all proved be superior over combination Ru/Al 2 O 3 zeolite.
