Abstract

Two mesoporous material Ni/γ-Al₂O₃ catalysts were prepared and characterized by ICP-AES, XRD, and TPR. The differences in reaction activity between Ni-in-Al₂O₃ and Ni-on-Al₂O₃ were investigated for hydrotreating of crude 2-ethylhexanol. The results show that the Ni species (Ni-on-Al₂O₃) exhibit excellent hydrogenation activities at a wide range of H₂ pressure and space velocity, while the Ni species (Ni-in-Al₂O₃) exhibit similar activities with those of Ni-on-Al₂O₃ only at higher H₂ pressure and lower space velocity. Due to the presence of extensively exposed Ni species on the Ni-on-Al₂O₃ catalyst, its hydrogenation performance was increased significantly because of the low interphase mass transfer resistance.
