BIOREFINERY PROCESSES FOR GREEN FUELS AND HYDROGEN GENERATION: CATALYTIC STUDY IN THE HDT REACTIONS OF O-XYLENE MODEL COMPOUND

Several CoMo and NiMo supported catalysts were prepared, sulfided and tested in the HDT reactions of o-xylene model compound. Cobalt based catalysts show a higher acidic character, which drives to a larger activity versus both isomers and polycondensated products. Then, the metal properties affects the catalytic pathway, leading to preferential formation of p-xylene on CoMoS2 catalysts.
