Effect of support-active phase interactions on the catalyst activity and selectivity in deoxygenation of triglycerides

Popis výsledku v původním jazyce

Three industrially important supports, SiO2, TiO2 and Al2O3, were used for preparation of NiMo catalysts (3.3 wt.% Ni and 15.0 wt.% Mo) and used in deoxygenation of rapeseed oil in presence of hydrogen (3.5 MPa) at 260-300 degrees C and liquid feed weight-hourly space velocity in the range 2-8 h(-1). Due to the same method of preparation and activation (sulfidation) of the catalysts, the final properties were affected mainly by the differences in the nature of supports as well as their properties, suchas specific surface area, pore size distribution or acidity. Most notably the dispersion of the active phase decreased in the following order SiO2 > Al2O3 >TiO2. As a result, the SiO2-supported NiMo catalyst exhibited smaller extent of hydrogenation reactions and a larger extent of decarboxylation. On the other hand, the TiO2-supported NiMo catalyst exhibited increased selectivity to hydrodeoxygenation products, plausible due to the larger active phase cluster size and broad pore size di
