EFFECT OF MO CONTENT IN MO(X)/γ-AL2O3 CATALYSTS OVER THE CONVERSION OF 2-METHOXYPHENOL AS LIGNIN-DERIVATES COMPONENTS

The effect of Mo loading (10, 12, 15, 17 and 20 wt.%) on the physicochemical properties and reactivities of Mo(x)/γ-Al2O3 sulfide catalysts for the conversion of 2-methoxyphenol at 573 K and 5 MPa of hydrogen pressure were studied. The catalysts were characterized by specific area (S BET),...
