AB - An effect of phase compositions (rutile, Rut and anatase, Ant) of TiO2 supports on the selective hydrogenation of
furfural to furfuryl alcohol was investigated. The 15%wt Ni/TiO2 catalysts were prepared by incipient impregnation method. The result showed that Ni supported on anatase-rutile mixed phase TiO2 (91% Rut and 9% Ant, A2)
provided the highest furfuryl alcohol yield at 43.8% due to the relatively strong Ni-TiO2 interaction, its appropriate crystallite sizes, and high average pore sizes. Furthermore, the effect of cobalt as a promoter on Ni/
TiO2-A2 catalysts was studied. The result showed that the Ni-Co/TiO2-A2 catalysts exhibited poorer catalyst performances compared to the monometallic Ni/TiO2, probably because addition of cobalt can lower the reduction
temperatures of Ni/TiO2 and weaken the metal-support interaction.
