Hydrodeoxygenation of isoeugenol was investigated at 200 °C under 3 MPa total pressure
in dodecane as a solvent, in hydrogen, over bifunctional Pt‐ and Ir‐modified Beta
zeolites and mesoporous materials. As a comparison, Pt and Ir supported on Al2O3, SiO2 and mesoporous MCM‐41 were also tested. The catalysts were characterized by XRD,
CO pulse chemisorption, transmission electron microscopy, scanning electron microscopy,
nitrogen adsorption and FTIR pyridine adsorption desorption. The results revealed
that the most active and selective catalyst was Pt‐H‐Beta‐300, which exhibits the
lowest acidity and largest crystal size of Beta zeolite among the studied Pt‐ and
Ir‐modified Beta zeolites. Complete conversion of isoeugenol and 89 % selectivity
to propylcyclohexane was obtained with this catalyst in 240 min. The overall deoxygenation
selectivity was 100 %, giving dialkylated cyclohexanes as the second major product.
The catalyst was regenerated, reduced and reused in the hydrodeoxygenation of isoeugenol
with almost the same performance as the fresh catalyst. Thermodynamic analyses and
kinetic modelling of the data were also performed.
