Abstract:
The hydrodeoxygenation of guaiacol, a compound modeling biooil, has been investigated. Experiments have been carried out in an autoclave at 280, 320, and 360°C and an initial hydrogen pressure of about 17 MPa using a Ni–Cu/SiO2–ZrO2–La2O3 catalyst. A formal kinetic model of the first stage of guai acol hydrodeoxygenation is suggested. It is assumed that the reaction is firstorder with respect to both guai acol and hydrogen. The model takes into account the deactivation of the catalyst and the decrease in the con centration of the deactivating compounds due to their hydrogenation. A possible cause of deactivation is the formation of coke and heavy intermediates, as well as the competitive adsorption of intermediate products of guaiacol conversion on the active sites of the catalyst. The parameters with which the model satisfactorily fits the observed dependence of the guaiacol concentration on the reaction time have been determined.
