Influence of binder on catalytic performance of Ni/HZSM-5 for hydrodeoxygenation of cyclohexanone

The influences of binders (alumina, silica sol, kaolin) on the performance of Ni/H-ZSM-5 for hydrodeoxygenation of cyclohexanone were investigated in a fixed-bed reactor. N2 sorption, X-ray diffractions, H2-temperature-programmed reduction, transmission electron microscopy, 27Al MAS NMR, and temperature-programmed desorption of ammonia were used to characterize the catalysts. The obtained results exhibited that porosity and acidity of the catalysts were strongly influenced by the binders. The most outstanding catalytic performance was observed on catalyst with alumina binder, which bears a well-developed pore structure and more acid sites than the others. Thus, alumina was chosen as the optimum binder to Ni/HZSM-5.
