Co-processing of fossil feedstock with lignin-derived model compound isoeugenol over Fe-Ni/H-Y-5.1 catalysts

Co-processing of n-hexadecane with lignin derived isoeugenol as a model compound was investigated in this work using low-cost mono- and bimetallic iron nickel supported on H-Y-5.1 zeolite. Different Fe-Ni metal ratios the catalyst led to different reaction rates processes product distribution. The presence just 0.26 wt% mixture made hydroisomerization-hydrocracking latter two-fold less active. Catalysts smaller particle sizes, lower than 6 nm were more efficient pointing out structure sensitivity. Extremely high activity co-processing obtained over 2 Fe – 8 Ni/H-Y-5.1 catalysts median size 4.6 metals-to-acid site ratio 8.6. much active hydrodeoxygenation, while cracking hexadecane observed Ni. Alkylation feature Ni/H-Y-5.1, whereas, 5 bifunctional no undesired oxygen-containing cyclic products detected. This exhibited highest hydrogen consumption according temperature programmed desorption, which can serve marker for hydrodeoxygenation. spent contained ca 40 coke predominantly aliphatic species.
