Computational Characterization of the Energetics, Structure, and Spectroscopy of Biofuel Precursors: The Case of Furfural-Acetone-Furfural. [PDF]

J Comput Chem
First‐principles computational characterization of the furfural‐acetone‐furfural adduct from structural motif and conformers to vibrational and electronic spectra. ABSTRACT Using density functional theory, we identify the 30 low‐lying structures of the furfural‐acetone‐furfural adduct, a valuable biofuel precursor.

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.
