Kinetic and Thermodynamic Analysis of Guaiacol Hydrodeoxygenation [PDF]

Catalysis Letters, 2019
Kinetics of guaiacol hydrodeoxygenation (HDO) was studied using supported MoxC–SBA-15 and as a comparison 5 wt% Pt/C under 30 bar hydrogen at 200 °C and 300 °C. Catalyst characterization was done by a range of physical methods including also determination of the amount of coke and the nature of adsorbed species.
